Sustainable Aviation
What is SAF in term of renewable energy?
SAF stand for “Sustainable Aviation Fuel,” which is a type of renewable energy that is used in the aviation industry.
Sustainable Aviation Fuel is a type of biofuel that is made from sustainable sources such as agricultural and forestry waste, non-edible crops, and municipal waste. The fuel can be used in existing aircraft engines without the need for any modification, making it an attractive alternative to traditional fossil fuels. SAF can reduce the carbon emissions associated with air travel by up to 80% compared to traditional jet fuel.
SAF is gaining increasing attention as a way to help the aviation industry reduce its carbon footprint and meet climate targets. Several airlines and aircraft manufacturers have already started using SAF as part of their sustainability efforts.
Type of sustainable aviation fuel
There are several types of Sustainable Aviation Fuel (SAF) that can be used in the aviation industry.
Here are a few examples:
Hydroprocessed Esters and Fatty Acids (HEFA)
This is one of the most commonly used types of SAF. It is made by converting plant oils and animal fats into jet fuel through a refining process called hydroprocessing.
Fischer-Tropsch (FT) fuels
These fuels are made by converting biomass or natural gas into a synthetic liquid hydrocarbon. FT fuels have a high energy density and can be blended with traditional jet fuel in varying amounts.
Alcohol-to-Jet (ATJ)
This type of SAF is made by converting sugars from non-food biomass, such as wood chips or agricultural waste, into alcohols. The alcohols are then converted into jet fuel through a refining process.
Bio-methane
This type of SAF is made by capturing and refining methane gas produced from agricultural waste, landfills, and other organic waste sources.
Power-to-Liquid (PtL)
This type of SAF is made by using renewable energy sources, such as wind or solar power, to produce hydrogen gas through electrolysis. The hydrogen is then combined with carbon dioxide from the air to produce a liquid hydrocarbon fuel.
These and other types of SAF are being developed and tested by companies and organizations around the world as part of efforts to reduce the carbon footprint of air travel.
Latest development of sustainable aviation fuel
There have been several recent developments in Sustainable Aviation Fuel (SAF) that are worth noting:
Increased production
There has been a significant increase in SAF production capacity in recent years, with several new production facilities being built or planned around the world. This is helping to bring down the cost of SAF and increase its availability to airlines.
New feedstocks
Researchers are exploring new feedstocks for SAF, such as algae, which can be grown using wastewater and carbon dioxide. This could provide a more sustainable source of fuel than traditional biofuels.
Government support
Many governments around the world are providing financial incentives and regulatory support to encourage the production and use of SAF. For example, the European Union has set a target for SAF to make up 5% of jet fuel consumption by 2030.
Airlines commitment
Major airlines have made commitments to increase their use of SAF in the coming years. For example, United Airlines has pledged to purchase 1.5 billion gallons of SAF over the next 20 years, while Delta Air Lines has committed to replacing 10% of its jet fuel with SAF by 2030.
New partnerships
There have been several new partnerships between airlines, fuel producers, and other organizations to accelerate the development and adoption of SAF. For example, United Airlines has partnered with several SAF producers to help bring their fuels to market, while Boeing has partnered with a fuel cell manufacturer to develop an electric propulsion system for aircraft.
Latest Technology of sustainable aviation fuel
There are several emerging technologies that are being developed to produce Sustainable Aviation Fuel (SAF) more efficiently and sustainably.
Here are a few examples Latest Technology of sustainable aviation fuel
Waste-to-fuel
Researchers are exploring new ways to convert waste products into SAF. For example, a company called LanzaJet is using a process called gasification to convert agricultural waste into a type of SAF called Alcohol-to-Jet (ATJ) fuel.
Synthetic biology
Synthetic biology is a field of science that involves designing and engineering biological systems for specific applications. Researchers are using synthetic biology to create microorganisms that can produce SAF more efficiently and sustainably than traditional methods.
For example, a company called Synhelion is using synthetic biology to create microorganisms that can convert sunlight and carbon dioxide into SAF.
Renewable electricity
Another emerging technology for producing SAF is using renewable electricity to power the production process.
For example, a company called ZeroAvia is developing a process to produce SAF using renewable hydrogen generated from wind and solar power.\
Carbon capture and utilization
Carbon capture and utilization involves capturing carbon dioxide emissions and using them as a feedstock for the production of SAF.
This can help reduce the carbon footprint of the SAF production process. For example, a company called Carbon Clean Solutions is using carbon capture technology to produce SAF from carbon dioxide emissions.
Direct air capture: Direct air capture involves capturing carbon dioxide directly from the air and using it as a feedstock for the production of SAF. This technology is still in the early stages of development, but it has the potential to provide a truly sustainable source of SAF.
World largest sustainable aviation fuel Country
The United States is currently the largest producer and consumer of Sustainable Aviation Fuel (SAF) in the world, with several large-scale production facilities in operation and more under construction or planned. The country is home to many of the world’s leading SAF producers and has a strong commitment to developing and promoting the use of renewable energy in the aviation sector.
The US government has provided regulatory support and financial incentives to promote the production and use of SAF, including tax credits, grants, and loan guarantees for SAF producers. Additionally, several US airlines have made commitments to increase their use of SAF in the coming years, including United Airlines, Delta Air Lines, and JetBlue.
Other countries, such as the European Union, Canada, and Brazil, are also investing in SAF production and use, and are expected to increase their SAF production capacity in the coming years. The European Union, for example, has set a target for SAF to make up 5% of jet fuel consumption by 2030. However, the US currently leads the world in terms of SAF production and consumption.

Without doubt, stupidity is part of Trumpism, but it’s only a part.
Meanness is also essential. People with any real compassion for others don’t have what it takes to be a member of the MAGA base.
As Aristotle said (plus or minus): Only people who do not seek power and qualified to hold it.
In retrospect, the United States hadn’t gotten burned too badly until Donald Trump came along.

Good Monday everyone.
You know … there is an old saying. When one door closes … another one opens. Well this week in wind energy … a whole lot of doors were swinging.
Let us start in Washington. For months … the Pentagon had quietly stopped reviewing wind energy project applications. More than a hundred and fifty onshore wind projects … stuck in limbo. The Defense Department claimed that drones in Ukraine had changed the game. Wind turbines … they said … could blind radar to incoming threats. So they hit the brakes.
But on Thursday … a federal judge said … not so fast. Judge Karin Immergut … a Trump appointee no less … issued a preliminary injunction. Resume the reviews … she ordered. Follow the law Congress wrote. The law gives the Pentagon seventy-five days for a preliminary review. As of late July … not a single one had been completed since the halt began in May. When government lawyers were asked to name one project they had reviewed … they could not name a single one. The judge told them plainly. If you want to change the rules … go ask Congress.
Now … while one arm of the government was being told to do its job … another arm was writing checks. German energy giant RWE … handed back its American offshore wind leases. New York. California. Louisiana. In return … the U.S. Department of the Interior cut RWE a check for one-point-two-two billion dollars. RWE is the fifth developer to walk away from American offshore wind under this administration. The company had spent more than a billion dollars on those leases. Years of planning. Investment. Partnership with federal agencies. But RWE said there is simply no path forward to permit these projects … for the foreseeable future.
So where does the $1.22B go? Nine hundred million dollars into Louisiana LNG. Three hundred million into natural gas turbine reservations. Fifteen gas peaking projects across the country. A company that came to America to build wind farms … is now building gas plants instead.
But here is the thing about RWE. They are not leaving the wind business. They are leaving American offshore wind. Globally … RWE operates eighteen offshore wind farms. Four more under construction. And nearly seven gigawatts secured in the United Kingdom’s latest auction. America said no. The rest of the world said … come on in.
And speaking of Europe … TotalEnergies … the French oil major … just bought Shell’s entire onshore renewables business in Europe. Four gigawatts of solar and wind. Five hundred megawatts already running or under construction in Italy and the Netherlands. Three-and-a-half gigawatts more in the pipeline across Italy … the United Kingdom … and Spain. And in the same breath … TotalEnergies sold a fifty percent stake in a one-point-two gigawatt European portfolio to KKR … for an enterprise value of one-point-eight billion euros. Build it. Sell half. Keep operating it. That is the model.
Now let us fly east … to India. GE Vernova just landed a hundred-and-sixty-three megawatt wind order from American developer Enfinity Global. Forty-three turbines. Three-point-eight megawatts each. Headed for the Fatehgarh wind farm in Rajasthan. Deliveries start late this year. And those turbines will be built at GE Vernova’s factory in Pune … which can turn out fifteen hundred megawatts a year. India is pushing for five hundred gigawatts of renewable energy.
Meanwhile … up in Denmark … a Danish wind tower maker named Welcon is raising its voice. Swedish utility Vattenfall just won two offshore wind tenders in Denmark. But when asked whether they would use European-made turbines … Vattenfall would not say.
Welcon’s chief executive Jens Risvig Pedersen said … and I quote …
“It would be completely absurd not to buy European products for the two new Danish offshore wind farms. That would simply shut down the European industry.”
The Danish trade union Dansk Metal agreed. Chinese turbines … they said … should not be financed with Danish taxpayer money. Vattenfall says it has not decided yet. But the debate is on.
And finally … a milestone that happened so quietly … nobody noticed. The world just crossed three terawatts of installed solar power. It took ten years to build the first terawatt. Less than three years for the second. And not even two more years for the third. Seventy-four countries now have at least one gigawatt of solar installed. That is up from forty-two in twenty-twenty. BloombergNEF expects nine terawatts by twenty thirty-six.
But here is the catch. Without batteries … solar hits a ceiling. Places like Australia and California already have so much solar that electricity prices go negative during the day. You heard that right. They pay people to use power. The answer is battery storage. But batteries are not able to keep up with the pace of solar.
Now … if you step back from all of this … something interesting emerges. Nobody in these stories is arguing about whether wind works. Not the judge in Oregon. Not RWE. Not even the Pentagon. The debate has moved on. The question is no longer … can you build a wind farm. The question is … who gets to decide where one goes.
Think about that. A federal judge did not rule that wind turbines are safe or good or necessary. She ruled that the government cannot ignore its own laws. The science was not on trial. The process was.
RWE did not surrender its leases because offshore wind failed. It surrendered them because one government made permitting impossible … while eighteen other wind farms in its global portfolio kept spinning.
And TotalEnergies did not buy four gigawatts of European renewables out of charity. It bought them because Shell … an oil company … decided those assets no longer fit its strategy. One oil major’s exit is another’s entrance. The assets did not lose value. They changed hands.
That is the story underneath all these headlines. Wind energy has crossed a threshold that most industries never reach. It is no longer competing on technology. It is competing on governance. The turbines work. The economics work. The engineering works. What varies … country by country … is whether the rules of the road are clear enough for capital to show up.
And capital … as we saw this week … will always find the door that is open.
That is the state of the wind industry for the 10th of August … twenty twenty-six. Join us for the Uptime Wind Energy podcast tomorrow.
