Allen Hall: Well, the U. S. Department of Labor published a Skills First Hiring Starter Kit last fall, and this has touched off a broader discussion about worker qualifications. And in 2024, 81 percent of employers Uh, practice skills based hiring up from 73 percent in 2023 and just 56 percent in 2022, according to some research.
So it’s up by 30%, almost 30 percent right now since 2022. Now, an analysis by Indeed, which is a job site, found the number of job postings requiring at least a four year degree fell to 17. 8 percent in January of 2024 compared to about 20 percent in 2019. So the number of employers who are requiring degrees to even apply for a job has dropped and there are more employers looking for skills.
Rather than diplomas, which is an interesting trend. And Joel was mentioning before we started today that Elon Musk put out a Twitter post or I guess it’s an ex post now. about this particular topic.
Joel Saxum: Yeah. Today he’s, he put a post out. It says, if you’re a hardcore software engineer and want to build the everything app, please join us by sending your best work to code at X.
com. That’s not the important part. The important part here is what he states is we don’t care where you went to school or even whether you went to a school or what big name company you worked at. Just show us your code. And to me, I think that’s amazing because I guess there’s, it’s a pendulum swing. My whole life as a young person in the United States, it was, you got to get a good job.
You got to get a degree. You got to get a degree. You got to get a degree. And then you see that being beat into the culture. And then the cost of these degrees just going crazy over here, right now. I mean, an average four year degree, you’re paying 80, 100, a hundred thousand dollars plus just to get over or more, right?
Yeah. Alan’s, Alan’s giving me the thumbs up way more. So, so, you know, if, if I, if I I’m in Texas right here in Austin, if I want to go to UT Austin. It’s going to cost me like 40 to 45, 000 a year for your degree. That’s 180, 000 degree that like, that’s so, uh, like it’s so much of a hurdle to employment and to growing, uh, growing employment as a society and in good jobs, and I think that like, from my standpoint, I’ve always.
Try to lean on this. If you’re a hard worker, if you’ve got some skills, I don’t care where you’ve worked in the past, I don’t care what school you went to, or even if you went to one, if you can do the job, let’s do the damn job. And that’s my take on it.
Rosemary Barnes: Uh, so one thing that I think has changed recently is that in the past, like the reason why you would say you want X degree is because you want someone that has the knowledge that you would learn in that degree.
Um, but these days there’s like nothing that you can’t learn well on the internet, just as well as in a degree. It’s kind of insane the way that now that we have the internet available, it’s insane to keep on doing it in the same way. So I think now, yeah, like we can still have the same requirement that we used to have in terms of knowledge.
But it doesn’t need to be so gatekept by the universities. But that said, I do think that there’s some kinds of engineering, like a lot of what people call engineering, I don’t think needs a degree, you know, um, and especially the things that need engineering sign off. Like it’s really rare that you actually need to use your engineering judgment for something like that.
It’s much more often, you need to just check what’s being done, check what the design standard says, and make sure that it fits within that. I don’t think you need a degree for that. Where I think you need engineers is where something comes outside of the design standard so that an engineer can make sure that, you know, everything has been considered that should have and, um, you know, do the analyses that are required and just, you know, use their professional experience and education to make sure that, You’re not inadvertently doing something unsafe.
Joel Saxum: I think when, when engineering, when you talk engineering this way, the gap for me would be when liability rolls into place. So if you’re designing a bridge, I would like someone to sign off on that, that can demonstrate, demonstrate from. whatever training and these things that they’ve, they’ve achieved a certain level of being an engineer to, and in the States, that would be a structural engineer with a SCE stamp.
And that makes sense to me.
Rosemary Barnes: The higher the stakes, the less that you should be needing someone that has any sort of judgment applied to it. You know, it should be a really rigorous standard that was definitely developed by engineers. Um, make sure that that standard, you know, covers everything that it needs to.
And then the person signing off should just be saying that it, It has done what the standard says it should do. I don’t think that there is, or should be, a lot of individual judgment in place about, will this bridge fall down? Will this aeroplane fall out of the sky? Will this, uh, I don’t know, um, petrol station explode?
You know, like that shouldn’t be somebody’s like individual call on whether a valve is big enough or a bolt is replaced frequently enough. There shouldn’t be any judgment calls there. It should just be kind of, you know, do it as, um, as the design standard says. And that design standard is really rigorous and performed by engineers.
Phil Totaro: Let’s put it this way. As we’re talking about engineering, you know, I think skills based hiring is potentially more applicable than it would be, say, in like the medical field, for example. Like, I don’t want somebody who’s just watched a bunch of YouTube videos on surgery to perform brain surgery on me.
So, you know, there’s, I think there’s a difference. Uh, maybe we can, you know, there’s a bit more margin you can get away with. Uh, doing this sort of thing for engineering as, as society evolves and all that. But, uh, yeah, I, I don’t know if it’s applicable everywhere.
Rosemary Barnes: I think that sometimes like in Australia, I’ve never heard that term skills based hiring and until today, but I have noticed, you know, early in my career, people cared that I had my accredited engineering degree and was eligible to be a member of Engineers Australia.
I don’t know. It’s been decade, decades, more than one decade, probably since anybody cared about that for me. So I think it gets less important as you progress in your career. But one weird place where I have noticed that people really want an engineering degree is, uh, my project management roles for, um, construction of new wind farms, new solar farms and stuff.
And that strikes me as a place where you don’t need an engineering degree at all. That, that should be pretty easy. like work experience, you know, um, build, building up to it. I know heaps of people that would be excellent at that sort of role, um, that aren’t engineers. And there’s, you do need to understand, you know, what the regulations are technically and make sure that, you know, things are happening correctly.
So it’s not like it’s a non technical role, but it’s not one of those kind of creative engineering roles where you have to, you know, be. I don’t know, coming up with a lot of solutions on your, on your own. Um, so I think that that’s unnecessarily restricting something to, we don’t have that many engineers in Australia.
I think that, you know, there’s a lot of people that could do that role that don’t have an engineering degree.
Joel Saxum: And I think that that’s the basis of this report that came out from the department of labor in the U S here is you’re trying to, they’re trying to make the labor market less restrictive. Cause if you’re just going to put a thing in there and it says, you’ve got to have a degree for this.
You’ve got to have a degree for that. You got to, some of them don’t even make sense. Like I. Anecdotally, here’s one from the state of Wisconsin. You can be a substitute teacher in the state of Wisconsin, but only if you have a degree, a four year degree, but that four year degree does not have to be in teaching.
The four year degree can be in whatever you want. It can be from Rose Hulman University as an engineer. And, but you need that degree to go and sit in the math class for a day to make sure the students don’t revolt. That’s a weird one to me.

Allen Hall: Delaware has signed a major agreement with U.
S. Wind worth 128 million dollars, marking a key development in offshore wind infrastructure along the east coast. The deal enables installation of transmission cables through Delaware waters and the state park land to connect two Maryland offshore wind projects to the grid. Now, there’s a couple of interesting pieces to this agreement.
$200 million is gonna be allocated for electrical grid upgrades within Delaware, and that’s gonna be focused on improving reliability and capacity. $12 million is for the cable right of way, which is pretty typical. Uh, $76 million, uh, of renewable ener energy credits are gonna be transferred to the state.
Which, um, Phil will know a lot about that. And then there’s 40 million going to the community for coastal dredging projects, clean energy workforce training, scholarship initiatives, and state park improvement. So the thing that raises my awareness of these kind of transactions, having seen something similar happen up in New Jersey, is that every time there’s an offshore wind project off the coast of one of these East Coast states.
They seem to extract hundreds of millions of dollars from the developers for state projects that may or may not have anything to do with the electrical grid. But raise the price of offshore wind, it has to raise the prices.
Phil Totaro: Absolutely. Um, you know, everything’s got to be accounted for in, in the budget and, and anytime you start stuffing these, you know, political pork projects into, you know, some kind of budget allocation, it’s necessarily going You know, end up being paid for by the project developer, but then ultimately it gets passed on to us as rate payers, because how do you think the developer makes money?
They want to be able to sell the power to somebody, and that means they also have to increase the power purchase contract price that they ask. Um, what’s interesting about this is, okay, so this is a deal in Delaware. New York actually also just announced that they’re going to do another allocation round, but only for the power generation because they have, um, you know, all the electrical infrastructure already being built and paid for by the preexisting projects.
So they’ve got a, you know, spare capacity in the substations to be able to do the power offtake. So the industry is cheering and everybody’s assuming that it’s going to lower the prices for this, you know, sixth round in, in the state of New York. Um, Um, except when everybody still comes to the realization that we haven’t done anything about inflation in a meaningful way.
Interest rates have come down a tad. I’m sure that, especially in a state like New York, they’re always going to find ways to start plumping up the price of things.
Allen Hall: What was the Orsted agreement with New Jersey for a while? Was it 400 million, 500 million? 300. 300 million? Okay. And that was the federal money that was going to come to Orstead for developing the project, right?
And then the state of New Jersey wanted to take that as a lump sum,
Phil Totaro: or take all of it. And, and that’s, that’s exactly, you know, a good, a good example where, you know, it was, the whole, Reason that there was this federal allocation of funds to the project developer was said that it could offset some of the capex cost to the developer.
And when the states see that somebody is, you know, getting 300 million dollars to go. do something to the benefit and of their state. They all start getting dollar signs in their eyes and saying, well, why aren’t we getting some of that federal money? Uh, and they devise clever ways and say, Oh, well, we’re not going to sign the power purchase agreement with you, or, uh, allow you to go build or hook into this substation over here, unless you give us some of that money.
Uh, that, that’s basically what this amounts to.
Allen Hall: but isn’t in The interest of the state to put offshore wind in it. Like Delaware is not the easiest place to get to for power generation. Right. And it’s, it’s a, it’s a little tiny state. It’s like 2000 square miles. Uh, there’s not a lot of power plants on it.
They’ve closed down some of them. That’s how they get in the power on shore from us. Wind is a going right where an old coal generation factory was because the grid infrastructure, so it’s going to plug into it there. So the whole situation for Delaware is weird in that it’s relatively simple to hook up the wind turbines to the existing grid in Delaware.
But now U. S. Wind is basically paying, what, 100, 000 per square mile to upgrade the electrical grid in Delaware? That seems like a lot of money to me.
Joel Saxum: I think Phil was spot on when he said political pork projects, right? Because to me, these are all, it’s all like earmarks. When you listen, when you watch a bill go through in D.
C. or at the state level, wherever, the bill may be about, you know, How many chicken wings we can eat this week, whatever it is. And, and, and then there’s an, there’s things earmarked. And you want the chicken wing bill passed? Well, you’re also going to give me 10 million bucks for this racetrack over here.
And then I’m also going to get this, this thing passed in the same, the same breath. If you want that, you’re going to get this. And what it ends up doing is, is it’s shooting these. These people, these states, they’re gonna, they shot themselves in the foot multiple times. We saw it in New Jersey, right? Like, Dorstad took the right down, backed off, and said, like, we’re not doing this anymore.
And we’ve seen this play out, this, this, I guess this, this concept is in my head right now, this pendulum swinging, right? Like, you’ve seen I’ve seen energy projects or watched the history of energy projects around the world where local geographies, local governments got taken advantage of, and they got resources pulled from them.
That happens. And then the pendulum swings the other way, and they put so many regulations and so much stuff in there like this. Like, this, if you add these up, they signed a 128 million dollar bill. Agreement. Great. But then there’s going to be a 200 million electrical grid, 12 million for cable right away, 76 here, 40 here.
You’re stacking this thing up to a 300 plus million extra tab just to develop a wind farm. You’re going to shoot yourself in the foot because the pendulum is that then the pendulum is swung too far the other way and you’re using up, uh, monies that Could be used for other things that in, in, in the development process.
Phil Totaro: And let’s go back to Alan’s question, which is why would they not want to build offshore wind? I mean, the answer is, well, guess what? If you like creating jobs, particularly jobs in the new economy, if you like tax revenue, if you like providing clean electricity, et cetera, I mean, these are, these are things that You do want to get reelected.
I’m talking to the politicians now. You know, you do want to get reelected. This is the way to do it is to ensure that you’re creating opportunity within the state. Um, you know, they’re, they’re taking advantage of opportunity by getting the cash, but then it’s not necessarily going to the benefit of everybody in the state because where do you think that cash came from in the first place?
It’s all the tax revenue from all of us. Collectively, in the first place, whether it’s the federal government or the state government tax coffers that it comes out of, so we’re the ones paying for it. And yet we don’t actually have, you know, a say in how, you know, like Joel’s talking about these, these horse trades and deals that end up happening when somebody is trying to pass a bill.
We have no say in how. That haggling happens. We elect somebody and we expect that they’re going to do a job for us, but I don’t necessarily always agree with the job that’s being done by the politicians that have been elected. I may not have even voted for them, and yet they’re deciding my fate.
Joel Saxum: I think it, Phil, if we could do, let’s look at a model that has worked in the past that didn’t require a bunch of this stuff.
If you know anything about the state of Alaska and the permanent fund dividend, right? The oil and gas companies are pulling oil and gas. Very, they’ve been doing it since the seventies. They’ve been pulling a lot of value in oil and gas out of the, out of the ground up there. So what they do is they have to do a, use a portion of those proceeds to fund a fund that goes back to the state.
Okay. So that is a, that is an, uh, an after development cost. So you build that into your operating model. Instead of saying upfront, you got to pay us 300 million to do this. How about we work together? And maybe we get a couple cents for every kilowatt hour produced or something off of these offshore wind farms, like the state of Louisiana is doing.
That’s where these things should go, in my opinion.
Phil Totaro: And not for nothing, but Louisiana is also making these reinvestments into, you know, developing things around coastal erosion and, and protecting the, the natural resources that they’ve got there, which I think is actually important and necessary for them to be able to do.
But that’s a decision that they made. And, and structured it in a way where it’s not impacting the CapEx cost of developing the project in the first place. And that’s the key thing here.
Allen Hall: As wind energy professionals, staying informed is crucial, and let’s face it, difficult. That’s why the Uptime Podcast recommends PES Wind magazine.

Whether you’re an industry veteran or new to wind, PES Wind has the high quality content you need. Don’t miss out. Visit PESWind. com today. Well Rosemary, I’m getting a little tired of hearing the term clean natural gas and that it is so much less expensive to use clean natural gas instead of renewable solar.
Wind, hydro, uh, that, uh, it makes no sense. We have to tear down all the wind turbines, all the solar panels should go away because clean natural gas is a better, uh, energy source. And I think that’s a very US perspective.
Rosemary Barnes: Can I just have two problems with that? Clean, natural gas. In that the only word that’s unproblematic is gas.
We can all agree that it’s a gas, but, um, clean. I mean, I don’t even know what they mean. Uh, natural, it’s a, it’s a fossil gas, like a natural, we don’t say natural coal, natural oil, um, you know, it’s fossil gas, it’s methane, right? Like that, that’s, that’s what it is. Uh, it’s incredibly good. Marketing that, I don’t know, the term, um, came about well before we cared about climate change.
So it wasn’t for that, but natural, natural gas makes it sound much nicer than what it is, which is fossil, fossil methane. How are they calling it clean? What’s their, what’s their definition or just that it’s cleaner than coal?
Allen Hall: They’ve dropped the er part from cleaner than coal. And it is cleaner than coal, and I will give them that.
Rosemary Barnes: I think even that’s debatable because, um, with methane, there’s losses, you know, like, because methane is like 84 times as strong a, um, a greenhouse gas than carbon dioxide is. It really matters small amounts getting leaked, and there’s always leakage, especially from, yeah, where it’s extracted, but. in the pipelines all along.
And I know that, you know, I’ve been following a little bit the research that’s been done on this area. And especially now that we can monitor with satellites, we find more and more and more leaks and the carbon or the, you know, greenhouse gas intensity of, um, fossil gas is increasing and increasing and increasing the more that we know.
And I have seen some studies try and say that in a lot of situations, it’s actually, um, overall worse for the climate than, than coal. That’s not the mainstream view and it’s not true on every. Every type of project, you know, some countries are better at extracting it cleanly, more cleanly than others, but, um, yeah, I don’t know.
How can they get away with that clean, clean natural gas? Come on.
Allen Hall: Well, the comparison of the cost of clean natural gas to other energy sources, particularly renewables, is very U. S. focused. They’ll say, well, in the U. S., uh, wind is a lot more expensive, particularly offshore wind is a lot more expensive than putting a gas, uh, electrification plant in.
True. For right now. True. But the rest of the world is not that way. Because the U. S. is full of natural gas. Pretty much Joel can walk around his backyard in Texas, drop in a pole, and get natural gas to come out of it. It’s not that hard. But if you look at the rest of the world, it’s much harder to find natural gas and the prices are widely variable.
So this is why the U. S. can make this claim. The U. S. right now is paying about 4 per million BTU. Alright, not bad. The U. K. right now is 14. per million BTU. And Germany is about 1350, right? So they’re three times more expensive, almost four times more expensive than the United States. That changes the whole economics of natural gas versus renewables.
So we are seeing renewable energy go in big time in France and in Germany, in the UK, and a lot of other places, but maybe not as much in the United States, uh, at the moment because natural gas is so low. So, Rosemary, do you see the same thing that this U. S. argument is being using globally?
Rosemary Barnes: Well, I mean, it’s an argument about, uh, cost that ignores the climate impact, right?
So, I think you first, we need to start with this only argument only works if we don’t care about the climate at all, which a lot of countries do. Um, Yeah, I mean, to a greater or lesser extent, and obviously it’s easier to care about the climate if the cost difference isn’t so great. Uh, I do think it’s a very, a very US thing, but, um, even, I mean, it’s relevant everywhere and I’ve heard the term called the, um, the spark gap, like how different the cost is between, you know, creating some sort of energy service by electricity versus with, um, natural gas.
So, you know, it might be comparing, um, A electric heat pump for heating your home versus a gas boiler. Um, what’s the cost difference for, you know, getting your house to the temperature that you want it. And, you know, some places in the world it’s cheaper to do it with electricity. In more places it’s cheaper to do it with gas.
I think that the US is like one end of a big continuum of the whole world dealing with that exact issue, but it’s definitely at, at the end, I think.
Allen Hall: But every country needs to think about it for themselves, right? The economics in the United States are totally different than the economics in Germany, the UK, France, India, South America, Brazil.
They’re just totally different, and I think we’re getting caught up, at least in the United States, that globally, wind is not an answer. Globally, solar is not an answer. Globally, hydro is not an answer. That the only answer is LNG. Which is just a complete distortion of what the reality is. For the time being, the natural gas is easy in the United States.
Rosemary Barnes: It’s also, in terms of energy security, like, you’ve got the gas there, so you’re fine. Europe wants to get off gas regardless of how much it costs. I mean, that’s, that makes it extra, an extra incentive that is expensive. But they don’t have it, so they have to import it. So they would prefer to have energy security by, you know, having their own wind farms.
Peace. Um, so I think that the US fails to see that as well, that there’s an energy security like for most countries, having your own renewables is, um, more better energy security than having to buy that, you know, your gas and your oil in from other countries.

Well, a stark warning has been coming from Europe about wind energy’s supply chain growing dependence upon Chinese manufacturers and a Dutch government backed report report. Along with comments from former MI6 chief, Sir Richard Dearlove highlights concerns about cybersecurity risks and strategic vulnerabilities in the offshore wind sector.
Now the background on the Chinese manufacturers, I think it’s pretty well known to people in wind, but there’s six of the top 10 wind turbine manufacturers in the world are now based in China. And a lot of Chinese firms control the critical supply chain. Uh, it’s particularly for rare earth magnets, right?
And there is a significant risk and concern among Intel officials like MI6 and my guess is the CIA, Joel, and others that, uh, putting Chinese manufactured assets into your grid makes them vulnerable, uh, which I, I think has been proven out time and time again from other different sectors of manufacturer from.
As we learned, Wi Fi routers to cell phones and a variety of other things. It’s not inconsequential, but there does seem to be a big conflict coming among Europeans because there are developers that are really going after Chinese manufacturers, or at least talking to it. Is that going to stop now that the governments and the Intel officials are basically saying, don’t do it.
We’re just not going to even consider
Joel Saxum: it. I think that depends on how much control the grid operator has over these decisions, right? Like in the United States, you can, do your permitting, do everything, but at the end of the day, FERC has to sign off on your wind farm and they have the ultimate control from a federal level.
Um, so the operators may have some, some sway and some pull, but not at the end of the day, it’s not their choice whether this happens to them or not, or whether they get to install these, these turbines or not. But I think it, it’s a viable concern. In my opinion, if we’re looking on the world stage of who, Foreseeable future we may have a conflict with.
We don’t want the ability for someone that we’re in a conflict with to shut our energy supply down. Whether you’re in the UK and you’re Part of MI6 or were part of MI6. I guess you’re probably always a part of MI6 if you were a part of MI6. Does that make sense? Um, but you know, you don’t want the, a foreign operator or a foreign, you know, at that point in time, that could be an adversary to be able to have control over of what you’ve got going on.
Uh, power generation wise, because it’s, I mean, that’s, that’s a, it’s a matter of national security and that’s my take on it.
Phil Totaro: Well, and let’s, let’s also give some context to this because the developers in Europe were initially saying, Oh, we’re going to go talk to the Chinese to try and get commercial negotiating leverage against the Western OEMs saying, Hey, Hey, you guys are trying to pass on all these cost increases to us as project developers.
We don’t want to pay more, so we’re going to go talk to the Chinese and maybe we get some of their turbines. Now, fast forward five years, we just had a tender in France for offshore where even Western, you know, hardcore Western project development companies, and I’m talking like NG, EDF, they were all quoting their, their project proposals with, you know, 20 plus megawatt Chinese wind turbines.
The Chinese turbines have become more of an attractive option to developers that I believe are making bad decisions about whether or not they should be considering Chinese turbines in the first place. I don’t really think that’s They’re taking total cost of ownership into account. You know, the developer is the one making the decision on something that has profound impact to everybody that is downstream from a very early upstage, you know, development decision about what equipment to use.
And how is that going to be maintained? How much does it cost, et cetera, et cetera. And security almost doesn’t even come into the equation, uh, at all. For this week’s wind
Joel Saxum: farm of the week. We’re heading up to New York state, uh, by Allen there. Um, so the wind farm of the week is eight point wind. It’s a next era site in Steuben County, New York.
And we’re focusing on this one because it is a big one. Big wind farm, not in number of turbines, but in megawatts per turbine. Uh, this is one of the first tur, uh, wind farms in the United States to install the GE 5.5 megawatt 1 58, uh, meter rotor machine. Uh, cool thing about it is eight point wind.com that NextEra put together has a comprehensive safety plan.
a public involvement plan, and various fact sheets about partners, and what NextEra does, and how Steuben County is a leader in in the renewable energy space. So they’ve tried to, you know, be a little bit more forward and open with the residents around there about what’s going on with these big turbines being installed.
So this wind farm also has a 16 and a half mile transmission line that was put in. As a part of it to, uh, uh, connect to the grid managed by the New York ISO. Uh, and it’s also producing enough clean, renewable energy, uh, to power more than 46, 000 New York homes. Uh, it’s expected to, uh, provide more than 40 million in revenue to local governments to support schools, infrastructure, and vital services, such as fire departments, which is a hot topic these days.
Um, the payments to landowners are also estimated to be around 25 million over 30 year expected life of the project. So the Eight Point Wind Energy Center, uh, up in Steuben County, New York, you are the wind farm of the week.

Biggest Threat to Human Civilization
Until Donald Trump rose to power, I probably would have said climate change.
Now, I would say it’s world fascism, as the world’s power powerful nation, at least at this point, is no longer a democracy in any meaningful sense of the word.
The planet is faced with rule by sociopathic dictators with absolute authority.

Welcome to Uptime Spotlight, shining light on wind. Energy’s brightest innovators. This is the Progress Powering tomorrow.
Pete Andrews: Pete, welcome to the program. Good to be back. Yeah. See you face to face. Yeah. Yes. This is wonderful. It’s a really great event to catch it with loads of the. UK innovation that are happening in the supply chain. So it’s, yeah, really nice to be here.
Allen Hall: This is really good to meet in person because we have seen a lot of bolt issues in the us, Canada, Australia, yeah.
Uh, all around the world and every time bolt problems come up, I say, have you called Pete Andrews and Echo Bolt and gotten the kit to detect bolt issues? And then who’s Pete? Give me Pete’s phone number. Okay, sure. Uh, but now that we’re here in person, a lot has changed since we first talked to you probably two years ago.[00:01:00]
You’re a bootstrap company based in the UK that has global presence, and I, I think it’s a good start to explain what the technology is and why Echo Bolt matters so much in today’s world.
Pete Andrews: Yeah, absolutely. So, um, as you said, we’re a uk, um, SME, there’s a team of 13 of us based here in the uk. Yeah. But we do deliver our services internationally, but really focused on Northern Europe.
Yeah. But increasingly we’ve done more in the US and North America, a little bit in Canada. Um, but our big offering really is to help wind turbine operators and owners reduce the need to routinely retire in bulks. So we have a quick and simple inspection technology that people can deploy, find out the status of their bolt connections, and then.
Reti them if necessary, but the vast majority of the time we find that they’re static and absolutely fine and can be left [00:02:00] alone. So it’s a real big efficiency boost for wind operators.
Joel Saxum: Well, you’re doing things by prescription now, right? Instead of just blanket cover, we’re gonna do all of this. It’s like, let’s work on the ones that actually need to be worked on.
Let’s do the, the work that we actually need to, and instead of lugging, like we’re looking at the kit right here, and I can, you can hold the case in one hand, let alone the tools in a couple of fingers. As opposed to torque tensioning tools that are this big, they weigh a hundred kilos, and those come with all of their own problems.
So I know that you guys said you’re, you’re focused here. You do a lot of work, um, in the offshore wind world as well. Yeah. I mean, offshore wind is where you add a zero right? To zeros. Yeah. Everything else is that much more complicated. It costs that much more. It’s you’re transitioning people offshore to the transition pieces.
Like there’s so much more HSE risk, dollar risk, all of these different spend things. So. The Echo Bolt systems, these different tools that you have being developed and utilized here first make absolute sense, but now you guys are starting to go to onshore as well.
Pete Andrews: Yeah, that’s right. So I mean, as as you said, that there’s really [00:03:00] three main benefit areas we focus on.
The first one is the health and safety of technicians, right? As you said, some of the fasteners used offshore now are up to MA hundred. So a hundred millimeter diameter bolts,
Joel Saxum: four inches for our American friends. Yeah, absolutely.
Pete Andrews: And they probably weigh. 30 kilos plus per bolt. Yeah. Um, so just the physical manual handling of that sort of equipment and the tightening equipment for those bolts is a huge risk for people.
If you think 150 bolts lifting or maneuvering, the tooling around on on its own can cause all the problems. So as well as the inherent risk of the hydraulic kit failing. So occasionally we see catastrophic tool failure. Is, which have really high potential severity, you know, sort of tensioner heads ejecting or crush injuries from Tor.
So that is really a key focus for our customers, just to [00:04:00] keep their teams safe, but also you have to be the cost effective and the the major cost benefit we allow is that we don’t have to revisit every bolt and every turbine like you’d have to do if you were retyping. So we believe there’s something of the order of a million pounds per installed gigawatt saving.
By moving from a routine REIT uh, maintenance strategy to a focused condition based inspection, you significantly reduce the amount of intervention you make and keep your turbines running more and reduce the boots on the ground on the turbine. So three real kind of, um, key. Benefits for people adopting our technology
Allen Hall: because we routinely see tower bolts being reworked or retention depending on who the manufacturer is.
And I’m watching this go on. I’m like, why are [00:05:00] we doing this? It seems, or the 10% rule, we’re tighten 10% this year, and they’ll come back and see how it’s going. That’s a little insane, right, because you’re just kind of. Tensioning bolts up to see if one of them has a problem and then you just do more of them and we’re wasting so much time because echo bolts figured this out years ago.
You don’t need to do that. You can tell what the tension is in a bolt ultrasonically, which was the original technology, the first gen I’ll call it, uh, that you could tell the length of the bolt. If the length of the bolt is correct within certain parameters, you know that it is tension properly. If it’s shrunk, that probably means it’s not tensioned properly.
That’s a huge advantage because you can’t physically see it. And I know I’ve seen technicians go, oh, I could take a hammer and I can tell you which ones are not tensioned properly wrong. Wrong. And I think that’s where equitable comes in because you’re actually applying a a lot of science simply [00:06:00] to a complex problem because the numbers are so big.
Pete Andrews: Yeah, I mean that, that, that’s been the real. Driving force between our offering is to simplify it. So ultimately we’re based on a non-destructive testing technique. It’s an ultrasonic thickness checking technique, but when from the non-destructive testing background, it’s crack detection, people have time, they can be, it’s a very precision measurement.
People have to be trained in the wind industry. We’re trying to inspect. A thousand, 2000 bolts a day at scale. It’s a completely different, um, ask of the technology and the way the technology has been developed historically has required too much technician expertise, too much configuration and set up time, and hasn’t delivered on the, on the speed that’s needed to be efficient in wind.
And that’s where our bolt wave [00:07:00] unit we’ve, that we’ve developed over the last. 18 months, let’s say, where all of our focus has gone to make it as slick and as easy for a client technician to pick up with minimal training. It’s through an iOS interface. Everyone understands it intuitively. Um, it’s a bit like using the camera app on your phone.
You know, you’re just hitting measure, measure, measure, measure, measure 10 seconds a bolt as you move the, um, ultrasonic transducer across, and then the data gets moved. Automatically to the cloud, to our bolt platform. And customers can view it in near real time. The engineer in the office can see the inspections happened.
They can see if there are any anomalous bolts, and then there can be communication there and then whether an intervention is necessary. So it’s sort of really changed the way our customers think about managing their, um. They’re bolted joints.
Joel Saxum: Well, I think these are, these are the kind of innovations that we love to see, right?
Because [00:08:00] we regularly talk about a shortage of technicians, and this isn’t, I was just learning this this week too, like this is not a wind problem. This is a everywhere problem. No matter what industry you’re in. Use are short of technicians. But we’re seeing like a tool like this is developed to be able to scale that workforce as well.
Right. You don’t need to be an NDT level three expert to go and do these things. ’cause there’s a very few of those people out there. Right? Right. We know the NDT people, a lot of NDT people, and that’s a hard skillset to come by. Yeah. This can be put in the hands of any technician. Yeah, a quick training course.
Just, Hey, this is how you use your iPhone. You can check Instagram, right? Yeah. Okay. You can off figure. Yeah, have fun. See you at lunch. Um, but they can, they can make this happen, right? They can go do these inspections and you’re getting that, that, uh, data collected in the field. Centralized back to an SME that’s looking at it and you don’t have to put that SME in the field and try to scale their ability to go and travel and do all these things.
They can be in the office making sure that the, the QA, QC is done correctly. I love it. I think that that’s the way we need to go with a lot of things. [00:09:00]Uh, and you’re making it happen.
Pete Andrews: Yeah. And it’s a real kind of. F change in mindset for us. So originally when we started Ebot, we were using third party hardware.
Yeah. Which required a bit of that specialism. Yeah. A bit of care about the setup of the project, getting multiple parameters configured before you got going. And it wasn’t really something we could put in the hands of a customer.
Joel Saxum: Yeah.
Pete Andrews: Which meant Ebot scale was limited to what our own team could go and do, and regionally as well.
You know, so we’re UK based. Probably 60% of our customers are uk, but now we have this Northern Europe offshore wind is obviously on our doorstep, but then increasingly we’ve done more and more in North America, so we’ve probably been to five or six sites now in North America and expect that to be a growth market because we can, we can now ship the devices over there, give some virtual training help.
Uh, [00:10:00] people set themselves up and then that opens up that market, you know, so it’s been a real change in strategy for us, but has allowed us to have far more impact than we otherwise would just try to be a pure service.
Allen Hall: Well, let’s talk about the big problem in the states of a minute, which are the root bushing or inserts that are loose in some blades.
When you lose that pushing, you also lose the tension on the bolt that can be measured. Is that something you’re getting involved with quite a bit now because of just trying to determine how many bolts are affected and, and where we are on the safety scale of can we run this turbine or not? Is that something that EE bolt’s been looking into?
Pete Andrews: Yeah, absolutely. So I, I’d say there’s sort of two halves of what we do. There’s the, there’s the bulk wholesale monitoring of. Typically static connections to eliminate this routine retitling where it’s not needed typically, typically. But then we have these edge cases of certain [00:11:00] connections and certain platforms that have known bolt integrity problems, and we are working with clients to really, um, manage those integrity risks.
Blade stud is an absolute classic, you know, sort of, I think almost every turbine OEM on some, if not all of their platforms has got. Embedded risk into their blades, pitch bearing connections. Um, so yeah, exactly as you said, our customers are using the technology for two things really. One is to ensure the bolts have been tightened to the preload that was specified or the target window.
And quite often we find there is an opportunity to increase the preload and therefore increase the resistance to fatigue failure. So. You know, particularly on older sites where the bolts perhaps not in the condition they were on day one. Well, they definitely won’t be. Um, when people have gone and retti them, they haven’t got back to where they, they should be.[00:12:00]
So we can prove that and increase a bit of that resilience, but then also start to look for the segments around the joint where, um, the bolt might start loosening or failures are occurring, and find areas where they can really hone in. And actively manage risk. And that sort of leads to what we’ve decided to do for the next year, particularly with Blade Stud in mind, is evolve this technology.
So whilst it’s also measuring the elongation, we will do a defect scan at the same time. So you’ll monitor your blade stu, um, connection and we’re hoping that we can set the device to flag to you there and then. We believe this bulk has got a defect while you’re here, get it changed out before it fails and, and all the knock on problems, um, from there.
Joel Saxum: So what you’re just pointing to there is a, is a workflow, right? So to me that is typical [00:13:00] of some of the amazing, innovative companies in the UK that I’ve run into throughout my career. And that is, you’re a group of SMEs, you know, bolted connections. That’s what you do, right? But then you’re like, hey. If there’s a tool, we could make a tool that would make our lives a bit easier, then it’s like, well, we could make the entire industry’s lives a little bit easier as well.
So let’s iterate on that. And now you’re able to send these kits around the world to look at these things. Hey, you have a problem with this specific model. We can help you with this because we know the failure mode and we know how to look for it. Let’s do that for you. Also here, you’re doing bolt bulk measurements.
We got that for you. But it all kind of flows back to the fact that Echo Bolt is a team. A bolted connection, SMEs that are making tools and being able to also provide consulting if need be. Yeah. Right. Um, to, to an entire industry. And I think that, um, this is my take on it, right? Wind is stop number one. I think you guys are gonna do a fantastic year, but there’s a lot of, uh, opportunity out there in bolted [00:14:00] connections as well.
Allen Hall: A tremendous amount blade bolts being broken from defects in the crystalline structure. What appears to be a more. Rapidly developing issue across fleets that I’ve seen. I went to a farm this summer and the number of blade bolts that were there on the table that were broken on the conference room table was And the whiteboard office.
Yeah. Yeah. This one,
Joel Saxum: this one.
Allen Hall: Your hard head is not gonna protect you from this one. It’s, it’s, it was this, um, I couldn’t imagine the amount of time they were spending hunting these things down. And of course, the only way they were finding ’em was they were broken. You like to catch ’em before they break because it becomes
Joel Saxum: a safety risk.
Just not too long ago we saw an insurance case where there’s an RCA going on and it is pointing at an entire tower came down. Right. And it is pointing at a mid, mid tower section bolted connection. How often do you guys run into those problems? Or are you contacted by insurance companies or anything like that to, to take a peek at those?
Pete Andrews: We haven’t done anything directly for insurance [00:15:00]companies, but we have been engaged by. Engineering consultancies that are doing RCA type activities. Okay. Um, things like at the end of defect liability periods mm-hmm. A customer has, has seen, they’ve had a lot of, uh, issues from an OEM, maybe an OE EM has offered a modification or an upgrade, assessing whether that upgrade is actually solved the problem or not.
We’ve got involved in, um, but the tower. Issue specifically. It’s actually very rare we find, um, problems with tower connections, but where we do is often where they haven’t achieved good flange flatness, ah, during installation or the bolts have been, let’s say, left out in the elements for a period and lubrication has been, has deteriorated before the bolt’s been installed.
So there are cases out there, but what I would say is. [00:16:00] To think about your whole life cycle, so ensure the bolt’s installed correctly and we can help with that with a QA to say, yes, this torque or tightening method has got you to the load that you want. Do some through life monitoring, but often if you install it correctly, it will it’s operational life.
You will have very little concern. But then in the UK market, we’re increasingly getting involved again at the end of life, right? Life extension where life extension turbines are 20, 25 years old. How does an operator make a decision to carry on running without replacing all bots? Um, and that’s where increasingly we being asked to use the technologist just to say, actually the joint is fine.
The bolts have run in a good, um, operational envelope. Run them on. Don’t replace a hundred percent of them like you might have been recommended to from your, um, yeah. Turbine supplier side. [00:17:00]
Allen Hall: So Pete, if someone’s doing a repower where they’re basically putting a new one in the cell on an existing tower, they’re making a lot of assumptions about all the bolts from the ground up that they’re gonna be okay.
And I know we’re talking about that. We’re in a lot of installations where. If the turbine has gone through a repowered or two. So now those bolts are 20 years old. Yeah. And trying to get ’em to
Joel Saxum: 30 35. 35
Allen Hall: 40. Yeah. I don’t know what they’re doing. By those bolted connections. Are they just like replacing the bolts?
Are they hitting ’em with a hammer again? Is that the, yeah,
Pete Andrews: I mean, they might replace ’em, but you’ve got a problem with the foundation bolts. ’cause they’re obviously often anchor bolts set into concrete, so you have to reuse them and. With the projects, both in wind and in process power industry with the chimney stacks to try and ascertain whether foundation bolts that are set into concrete are still suitable for operations.
So look for corrosion losses, look for [00:18:00] defects. Um, so yeah, they’re all things that need thinking about before you just make the snap decision to repower. But I think
Joel Saxum: a lot of that, uh, going back to a couple minutes ago, you were talking about at the commissioning phase, making sure that you have proper qa, QC of how these things were installed day one, and then making sure that before commissioning of a turbine, they’re checked.
I think that’s really important. We’re starting to see that in the blade world now too, where we’ve been talking about it for a long time, and now when you talk to operators, they’re like, we’re getting inspections done on the blades before they’re hung. Or at the factory before they’re hung. After they’re hung.
Like they want a good foundation baseline. Are you seeing that in the bolted connection world too?
Pete Andrews: Yes. Sort of. It’s just emerging for us. What we’ve found is, so most of our customers are in the operational phase ’cause they are the ones feeling the pain. Yeah. Of the routine retitling work. When they do major components, they sometimes engage us to come and say, can you check [00:19:00] before and after the blade was removed?
What was it? Before we took it off from a a bolt load perspective, what is it afterwards? Can you then recheck after 500 hours When we retalk it? And what we’ve seen there often is the initial install hasn’t got them to where they needed to be and they’ve had to go and do the break in maintenance or the 500 hour REIT to get the bolts to the right load.
So one of the questions that we have is whether. Some of the defects are actually being initiated very early on in that initial running in period and whether if, if actually you’d taken the time at, at the point of assembly to make sure you were correct, whether that avoids some of the knock on integrity concerns.
So yeah, it’s interesting area.
Allen Hall: Well, bolts are what hold wind turbines together and you better know you have the right. Tension and [00:20:00] torque on your bolts to get to the lifetime of the wind turbine and to, and to check it once in a while. And I know there’s a lot of operators I can think of right now in the United States that are sort of doing that job somewhat.
I I think they have missed out on opportunities to save a lot of money and to call it echo bolt. How do people get ahold of you? Because that’s one thing I run into all the time. Like, Hey, hey, you gotta talk to Ebol, call Ebol. How do they get ahold of you?
Pete Andrews: So the easiest ways are via our website. Which is echo bolt.com.
Um, LinkedIn, you’ll find us at Echo Bolt on LinkedIn. Reach out. Our email would be info@cobolt.com. So any of those route and you’ll, uh, reach me and the team and more than happy to speak to you about any of your faulting concerns or problems. We are, uh, yeah, we’re passionate about your problems.
Allen Hall: Pete, thank you so much for being on this podcast.
I, it is great to actually see you in person and see the bolt wave technology. It’s really [00:21:00] impressive. So anybody out there that needs bolt tensioning to checking tools, you need to get ahold of Pete at Echo Bolt and get started today. Thank you Pete. Thanks guys. It’s great to be here.
Renewable Energy
Carbon Capture and Synthetic Fuels
As we’ve noted in the past, the idea of capturing CO2 from the atmosphere is completely unfeasible, since 99.96% of the air around is something other than CO2 (mostly nitrogen). However, there are environments that change this equation radically, cement plants being one of them, where the concentration of CO2 emissions is as high as 30% (versus .04%).
Now, this brings the subject of synthetic fuels into the realm of possibility. Sure, if you want to make gasoline, diesel, and jet fuel, you’ll need two other things: hydrogen (which can come from electrolyzing water), and a considerable amount of energy, as these processes are heavily endothermic, meaning that energy must be supplied from external sources.
The good news is that we have enormous amounts of off-peak wind and nuclear that are wasted every day. Please see: Doty WindFuels.
