Understanding Power-to-Liquid (PtL) Technology
In our quest for sustainable energy solutions, researchers and engineers are continuously exploring innovative technologies that can effectively harness renewable energy sources and address the challenges associated with energy storage.
Power-to-Liquid (PtL) technology is one such groundbreaking concept that offers a promising solution for converting surplus electricity from renewable sources into liquid fuels. This article delves into the concept of PtL, its working principles, potential applications, and the benefits it brings to the table.
Power-to-Liquid (PtL) technology involves the conversion of electrical energy into liquid fuels, such as synthetic hydrocarbons or renewable gases, using various chemical processes. It integrates renewable electricity generation, carbon capture, and fuel synthesis to create a closed-loop system that enables the storage and distribution of renewable energy in the form of easily transportable liquids.
Working Principles of PtL
PtL technology typically follows a multistep process that begins with the production of hydrogen through water electrolysis. Renewable electricity powers the electrolysis process, splitting water molecules into hydrogen and oxygen. The hydrogen produced can be further combined with captured carbon dioxide (CO2) from various sources, such as industrial emissions or direct air capture, to create valuable carbon feedstocks.
Subsequently, the hydrogen is combined with CO2 in a chemical reaction, often through the Fischer-Tropsch synthesis or methanol synthesis. Fischer-Tropsch synthesis involves the conversion of syngas (a mixture of hydrogen and carbon monoxide) into liquid hydrocarbons, while methanol synthesis converts hydrogen and CO2 directly into methanol. These hydrocarbons or methanol can be further processed into a variety of liquid fuels, including synthetic diesel, jet fuel, or even methane.
Power-to-Liquid (PtL)-Production company
While specific capacity data may vary over time as companies expand their operations, here are some general capacity figures for Power-to-Liquid (PtL) production companies:
INERATEC:
INERATEC has a modular approach to PtL production, allowing for flexible capacity deployment. Their modular systems range from small-scale units with capacities of a few hundred kilowatts (kW) to larger installations with capacities exceeding several megawatts (MW). Their compact design enables easy scalability to meet varying demands.
Electrochaea:
As Electrochaea specializes in power-to-gas (PtG) and power-to-methane (PtM) solutions, their capacity figures relate to methane production. Their commercial-scale PtM plants typically have capacities ranging from a few hundred kilowatts (kW) to several megawatts (MW). Electrochaea aims to deploy larger plants with capacities in the tens of MW range in the future.
Sunfire:
Sunfire focuses on high-temperature electrolysis and Fischer-Tropsch synthesis for PtL production. While specific capacity data for their PtL plants is not readily available, Sunfire has successfully demonstrated their technology at a pilot plant scale, with a capacity of around 400 kW. The company’s modular approach allows for scalability, and they have the potential to build larger PtL plants as demand grows.
LanzaJet:
LanzaJet’s focus is on sustainable aviation fuel (SAF) production. Their initial commercial plant, located in Georgia, United States, has an annual production capacity of 10 million gallons (approximately 37.9 million liters) of SAF. LanzaJet has plans for further expansion to increase production capacity in the future.
It’s important to note that capacity data can evolve as companies refine their technologies, secure funding, and implement commercial-scale production facilities. For the most accurate and up-to-date capacity information, it is advisable to consult the respective company’s official communications, announcements, or websites.
Applications and Benefits of PtL Technology
Energy Storage: One of the significant advantages of PtL technology is its ability to store surplus renewable energy in the form of liquid fuels. This offers a practical solution to the intermittent nature of renewable energy sources like wind and solar, allowing for on-demand energy availability. PtL fuels can be stored for an extended period and distributed through existing infrastructure, making it a versatile option for long-term energy storage.
Decarbonization of Transportation: The transportation sector heavily relies on fossil fuels, contributing to greenhouse gas emissions. PtL technology provides a pathway for decarbonizing this sector by producing synthetic fuels with a significantly reduced carbon footprint. These fuels can be seamlessly integrated into existing transportation infrastructure, eliminating the need for costly infrastructure modifications or vehicle replacements.
Carbon Neutrality: PtL fuels can be synthesized using captured CO2 from industrial processes or directly from the atmosphere. By utilizing CO2 as a feedstock, PtL technology facilitates the recycling of carbon emissions, significantly reducing net greenhouse gas emissions. This not only helps mitigate climate change but also provides a way to repurpose CO2 that would otherwise be released into the atmosphere.
Fuel Flexibility: PtL technology enables the production of various liquid fuels, such as gasoline, diesel, jet fuel, or even renewable methane. This versatility ensures compatibility with different modes of transportation, including cars, trucks, ships, and planes, without requiring major modifications to existing engines or infrastructure. It provides a seamless transition to a sustainable energy future without compromising convenience or performance.
Conclusion for Power-to-Liquid (PtL) technology
Power-to-Liquid (PtL) technology represents a significant step towards achieving a sustainable energy ecosystem by efficiently converting renewable electricity into liquid fuels.
With its potential for large-scale energy storage, decarbonization of transportation, carbon neutrality, and fuel flexibility, PtL offers a viable and promising solution to some of the major challenges associated with renewable energy integration. As research and development efforts continue, PtL technology holds the key to a gre

New Jersey’s Electricity Rate Crisis Is A Perfect Storm for Wind Energy

New Jersey’s Electricity Rate Crisis Is A Perfect Storm for Wind Energy
New Jersey ratepayers received an unwelcome surprise in June 2024 when electricity rates jumped between 17 and 20 percent virtually overnight. But behind the dramatic increase is a much larger story about the challenges facing renewable energy deployment, grid modernization, and the future of power generation across the PJM Interconnection region—one that has significant implications for the wind energy industry.
According to Kyle Mason, Associate Planner at the Regional Plan Association, the rate spike stems from record high prices in PJM’s annual capacity auction, which secures power for peak grid loads. PJM operates the grid for New Jersey and 12 other states, covering over 60 million people. The capacity market’s unprecedented pricing “trickled down to increased electricity rates for New Jersey rate payers,” Mason explained.
Old Grid, New Demands
“We have a very old grid, and we’re trying to update it in real time,” said RPA’s Robert Freudenberg – while bringing more energy onto the system. “It’s like trying to build the plane while you’re flying it.”
Freudenberg, Vice President of the Energy & Environment Program at RPA, described the crisis as a convergence of multiple factors: the grid’s age presents challenges, the interconnection process has slowed dramatically, and demand is skyrocketing.
The interconnection queue process, which once took a few years, now stretches across many years. According to Mason, as of April of last year, over 200 gigawatts of projects sat waiting for study in the interconnection queue, with approximately 98 percent comprising solar, wind (both onshore and offshore), and storage. Even if only half of those projects eventually come online, Mason noted, “it would markedly improve the rate situation.”
Unprecedented Demand Growth
The energy demand situation is compounded by explosive load growth, driven largely by artificial intelligence and data centers. Mason noted that current projections show load growth reaching five percent annually—levels, he said, “we have not seen…since air conditionings were invented.”
These aren’t small facilities. “The industry is seeing massive, massive expansion of data centers,” Mason said. “Not just small data centers that we saw expand during the years leading up to the dot-com bubble, but rather these massive hundred-plus megawatt data centers,” primarily concentrated in Northern Virginia, New Jersey, Pennsylvania, and Ohio.
By 2030, data centers alone could account for 10 to 12 percent of electricity demand on the PJM grid—a staggering figure that underscores the urgency of bringing new generation capacity online quickly.
Offshore Wind “Ideal Solution” for Energy Island
New Jersey, the most densely populated state in the country, uses more energy than it produces. Thanks to that distinction and its geographic constraints, it’s referred to as an “energy island”- where wind represents an ideal solution for large scale generation.
The state had plans for approximately five gigawatts of offshore wind capacity, including the 1,100-megawatt Ocean Wind project, which has since been abandoned. Federal policy shifts have further complicated the landscape, effectively putting offshore wind development on ice across the region.
Freudenberg pointed to the South Fork Wind farm off Long Island as proof of concept.
“If you look at the data from that, [South Fork] is performing very well. It’s reliable,” he said, noting it put a thousand people to work and stabilized rates for customers.
Grid Reliability Challenges
Adding another layer of complexity, PJM recently implemented stricter reliability rules that dramatically reduced the amount of generation qualifying as reliable.
“The buffer dropped from about 16 gigawatts of supposedly reliable energy sources to about 500 megawatts when the reliability requirements were issued,” Weather Guard Lightning Tech CEO and Uptime Podcast host Allen Hall notes in the interview.
“Many fossil fuel plants face reliability concerns during extreme weather events, extreme cold events,” Mason explained. That made the older plants ineligible to enter PJM’s capacity market under the new rules. That caveat simultaneously removes baseload capacity while renewable projects remain stuck in the interconnection queue.
Is PJM’s Progress Too Little, Too Late?
PJM has made some progress addressing interconnection challenges. Working with the Federal Energy Regulatory Commission, the grid operator implemented a new cluster study process that prioritizes projects on a “first ready to serve basis” rather than first-come, first-serve. Mason reported they’ve already studied over 40 gigawatts of energy, “and that’s starting to get built,” Mason said.
“But there’s the question of whether that can outpace the rising demand,” he said.
On transmission infrastructure—a critical bottleneck for wind energy—the average timeline to build high voltage transmission lines stretches to 10 years. Mason noted projects face “years and years just to get the materials to build power plants, and then 10 years with permitting costs and supply chain issues and permitting timelines to build the transmission wires.”
Policy Recommendations: States to Lead the Way
Despite federal headwinds, Freudenberg urged states to maintain momentum on offshore wind.
“States need to keep the charge on for offshore wind. They need to keep the fire burning for it,” he said, recommending that states prepare transmission infrastructure and work with developers so projects can move forward quickly when federal policy shifts.
New Jersey has taken some positive steps, recently announcing its Garden State Energy Storage Program that targets over two gigawatts of storage capacity and releasing grid modernization standards for utilities.
Of course, when utilities are required to modernize, rate payers usually foot (most of) the bill. Still, having an available, reliable energy supply is the first order of business.
For wind energy operators and stakeholders, the New Jersey situation illustrates both the critical need for renewable generation and the complex policy, infrastructure, and market challenges that must be navigated to deliver it.
As Freudenberg summarized: “The ingredients here are so good for offshore wind. Everything… the proximity, the wind speeds. All we have to do is build those things and connect them into our grid and we’ve got a lot of power.”
The question is whether policy will allow that to happen before the grid crisis deepens further. We’ll be watching closely!

Chopin — Music that Inspires
There’s a story behind the piece below, Chopin’s “Heroic” Polonaise, performed by Vladimir Horowitz, the pianist most people deem to be the world’s top interpreter of Chopin.
Frederic Chopin was born in 1810 near Warsaw, Poland, and was known as a child prodigy as a pianist and composer by the time he was six or seven.
Russia had long ruled Poland, but in the 1820s, Russian rule grew more arbitrary, and secret societies were formed by Polish intellectuals in several cities to plot an insurrection. In November 1830, Polish troops in Warsaw rose in revolt.
Chopin moved to Paris shortly after his 22nd birthday, where he would spend the rest of his life composing, teaching, and concertizing, but his love for his native land remained fierce.
But what could he do? Chopin was a small and sickly person, barely five feet tall, perhaps 90 pounds in weight. He certainly couldn’t be a physical part of an uprising, but he could inspire his native Poles with his compositions.
There are a few good examples of his works along these lines, but the Heroic polonaise stands by itself. When I hear it, a single word comes to fore: bravery.
Enjoy, and don’t be embarrassed if you have goosebumps.

Doing What’s “Right” Is More Controversial than it Seems
Some of us are looking for a single, simple statement to encapsulate what is going so wrong in America today, and perhaps it relates to what Aristotle says at left here.
Even the MAGA folks think that what they’re doing is “right.” By this I mean white supremacy, mass deportation of immigrants (with or without due process), the rejection of science, and so forth.
