California renewables firm in talks for green fuel co-development

A utility-scale solar and storage developer based in California has started outreach and discussions to have green fuels projects co-developed at some of its larger sites in the western US.

RAI Energy, the California-based solar and storage developer, has started to engage with other companies about developing green fuels along with its utility-scale projects, CEO and owner Mohammed S. Alrai said in an interview.

RAI recently took a development loan from Leyline Renewable Capital. That transaction ends a process launched by Keybanc first reported by The Hydrogen Source.

Alrai remains the 100% equity owner, he said. The liquidity from Leyline will last about two years.

The company’s most impending projects are in Colorado and California, Alrai said. Discussions around green fuels envision a partner coming in as a co-developer and customer for RAI’s renewable power.

“We’re definitely open to entering into conversations with all stakeholders,” Alrai said, adding that the effort could require capital raising. “We will be coming to the market to potentially raise equity.”

RAI is moving toward long-term ownership and operation of projects, he said. The company could also sell projects to raise capital.

Lummus launches ethanol-based SAF technology

The company has made its ethanol to SAF process technology commercially available.

Lummus Technology, a global provider of process technologies and value-driven energy solutions, announced the commercial availability of its ethanol to sustainable aviation fuel (SAF) process technology, according to a news release.

The technology provides operators with a large-scale, commercially demonstrated solution to reduce the aviation industry’s greenhouse gas emissions.
“Lummus’ extensive commercial experience in all steps, including conversion of ethanol feedstock and production of the SAF process, gives us a unique advantage to help our customers produce sustainable fuels,” said Leon de Bruyn, president and Chief Executive Officer of Lummus Technology. “Our process leverages proven, commercial-scale technologies that we integrate to meet the aviation industry’s growing demand for SAF and support its decarbonization efforts.”

Lummus’ ethanol to SAF technology offers a safe and reliable solution by integrating ethanol to ethylene (EtE), olefin oligomerization and hydrogenation technologies in a process configuration that maximizes the final yield to SAF while minimizing CAPEX, OPEX and carbon emissions.
Central to this process is Lummus and Braskem’s technology partnership for producing green ethylene, which accelerates the use of bioethanol and supports the industry’s efforts towards a carbon neutral economy. Since 2010, Braskem has been operating an ethanol dehydration unit in Brazil. Using EtE EverGreen™ technology, the unit provides a proven and reliable foundation for producing 260 kilotons per year of ethylene from ethanol. Lummus has integrated this world-scale dehydration process with its light olefins oligomerization and advanced hydroprocessing technologies through Chevron Lummus Global, a joint venture with Chevron.

This integrated offering makes the entire ethanol to SAF value chain available for exclusive licensing by Lummus.

US salt cavern developer selling hydrogen storage project

A US-based developer of salt cavern projects for hydrogen storage has retained a financial advisor to sell its first project and is informally seeking an equity investor.

Phoenix Hydrogen, a salt cavern storage developer based in Berkeley, California, has hired a financial advisor to run a sale of its primary project in Arizona, according to two sources familiar with the matter.

Scotiabank is leading the process, which will launch next week, the sources said. The sale is for 100% of the company’s first project near Kingman, Arizona. The project is expected to reach FID in the next 18 months.

Phoenix CEO Shawn Drost said in an interview that the company is informally seeking a platform equity investment as well but is only willing to take on a minority partner. An equity sale would need to raise an amount in the “low-tens” of millions, he said. It’s a difficult proposition, as equity providers in the space tend to demand majority positions.

The company wants to bankroll projects from beginning to end as an owner operator, he said, but requires capital to do so.

Phoenix, a six-person team, has a relationship with GHD Group for EPC, he said. The company is seeking relationships with production-side developers to sign site and storage leases.

Scotiabank did not respond to requests for comment.

Exclusive: US-Ukraine battery storage firm in seed round

A US-based battery storage technology firm with operations in Ukraine and a utility-offtake pilot project in the southwestern US is in the early stages of finding institutional investors in the US and Europe.

SorbiForce, an Arizona-based battery storage technology firm, is raising $4.7m in seed funding with ambitions to find strategic investors for larger fundraising efforts in the next year, CEO Serhii Kaminskyi said in an interview.

The company, which was founded in western Ukraine and still has R&D operations there, aims to finish the seed round in five months, Kaminskyi said. Currently the US operations are housed at the University of Arizona Center for Innovation.

The batteries the company designs use little metal compared to other battery pack systems, instead using organic matter that can ultimately be biodegraded. The packs are filled with “ultra porous carbon materials” capable of storing up to 0.7 MWh.

SorbiForce is assisted by Orrick, Herrington & Sutcliff and Squire Patton Boggs as legal counsels, Kaminskyi said.

The seed round is for a 1 MW pilot project near Tucson, Arizona. That project has offtake contracted with Tucson Electric Power, Kaminskyi said. The B2B business model will be to sell batteries to customers in power generation, industrials, municipalities, and EV charging.

Kaminskyi, speaking from southern Italy, said the company is testing batteries in that country and has had discussions with offtakers in Germany, including automakers. The company has signed an agreement with a European energy company, he said, declining to name which.

The early-stage company is too-early for many financial investors, Kaminskyi said, and is looking for institutional investors with downstream need for battery storage.

“We’ve already received money from customers,” Kaminskyi said.

Russia’s invasion of Ukraine has put strain on the company, particularly concerning the families of the company’s founding employees, Kaminskyi said. The facilities in Ukraine are safe, but he is in process of moving those facilities to Arizona.

Kaminskyi owns 56% of the company, with additional equity held by the founding scientific team and US employees, he said.

Illinois ethanol company seeking offtaker for SAF project

Seeking to diversify into new markets, Marquis, a family-owned ethanol producer based in Illinois, is looking for an offtaker for its first sustainable aviation fuel plant.

Marquis, a family-owned ethanol producer based in Illinois, is seeking an offtaker for its first sustainable aviation fuel plant.

The company, which is developing the plant in partnership with LanzaJet, an SAF firm, recently completed a feasibility study for the project, and is looking for airlines or users of renewable diesel as offtakers, Dr. Jennifer Aurandt Pilgrim, the company’s director of innovation, said in an interview.

Marquis owns and operates a 400 million gallon per year ethanol plant – the largest dry-grind ethanol plant in the world – which produces sustainable ethanol for fuel and chemicals as well as a feed for the aquaculture and poultry industries.

The company will divert roughly 200 million of those gallons to make 120 million gallons per year of SAF and renewable diesel, Aurandt said, noting that Marquis is looking to branch into new markets where ethanol is a feedstock.

“As more electric vehicles come on, there will be about a 3 billion gallon demand destruction for ethanol, and SAF is one of the great markets that we can diversify into,” she said.

Aurandt said financing for the SAF facility will ultimately depend on who the offtaker is.

Use cases

United Airlines, Tallgrass, and Green Plains Inc. recently formed a joint venture – Blue Blade Energy – to develop and then commercialize SAF technology that uses ethanol as its feedstock.

SAF using corn as a feedstock does not currently qualify for incentives in the Inflation Reduction Act, which uses standards laid out by the International Civil Aviation Organization that effectively exclude corn-based SAF from qualifying.

Marquis and other ethanol producers are pushing for the adoption of a lifecycle greenhouse gas model, known as GREET, developed by the Argonne National Laboratory, that would allow corn-based feedstock to qualify, said Dustin Marquis, the company’s director of government relations.

The company is also looking to attract partners to set up operations in the Marquis Industrial Complex, which is touted as a 3,300-acre industrial site with natural gas lines, access to multiple forms of transportation, and carbon sequestration on-site.

“We’re looking for other businesses where there would be either vertical integration or business synergies between the two organizations,” Marquis said.

Marquis said in a news release it would develop two 600 ton per day blue hydrogen and blue ammonia facilities along with manufacturing for carbon neutral bio-based chemicals and plastics.

CO2 utilization

In its production process, Marquis makes 1.2 million tons of biogenic CO2 per year, and has applied for an EPA Class IV permit for sequestration.

“We like to say it’s direct air capture with the corn plant,” Aurandt said, adding that the CO2 is purified via fermentation to 99.9% pure, and will be injected into a formation that sits beneath the Marquis Industrial Complex.

The company is additionally developing a CO2 utilization project with LanzaTech, which would augment ethanol production using CO2 as a feedstock. The project was recently awarded an $8.54m grant from the US Department of Energy, the largest award in the category of corn ethanol emission reduction.

“We can increase the amount of ethanol that we produce here by 50%,” Aurandt said. “So we could make 200 million gallons of ethanol per year” from CO2, she added, noting that the pilot demonstration will be the largest CO2 utilization project in North America. It is expected to be operational in late 2024.

The SAF plant and the CO2 utilization project will use hydrogen for refining and as an energy source, respectively, Aurandt said.

Gas Liquid Engineering is the EPC for the CO2 unit, and Marquis will use compressors from Swedish multinational Atlas Copco.
