California SAF co. raises $3M, plans to open Houston lab

Armed with a fresh $3 million round of seed funding, Los Altos, California-based Universal Fuel Technologies is establishing a lab in Houston for production of sustainable aviation fuel samples.

TO VC led the round, with participation from Alchemist Accelerator, Claire Technologies, and World Star Aviation.

Unifuel’s Flexiforming technology consists of a series of chemical reactions that convert various sustainable materials — such as ethanol, methanol, and liquified petroleum gas — into high-quality SAF that’s similar in chemical composition to traditional jet fuel.

“Today’s SAF production is challenged by feedstock limitations and expense, which are problems Unifuel’s Flexiforming solves,” Joshua Phitoussi, managing partner at TO VC, says in a news release. “Unifuel has engineered a more efficient SAF production method that dramatically cuts costs while getting the most out of limited resources.”

One of the key benefits of Flexiforming is that it creates the molecules needed for jet engines and other aircraft equipment to run smoothly. The addition of Flexiforming’s SAF allows for a fully synthetic jet fuel that airlines would be able to use without blending with conventional jet fuel once ASTM International (formerly the American Society of Testing and Materials) approves 100% SAF.

“Sustainable aviation depends upon developing SAF that is not only cost-effective but able to work within the aviation industry as it stands today,” says Alexei Beltyukov, CEO of Universal Fuel Technologies. “With Flexiforming, we can give SAF producers the ability to make affordable, high-quality SAF that has the characteristics needed for aircraft performance and the flexibility to scale at their own rate.”

Houston-based Zeta Energy Corp. has teamed up with an automaker to develop new battery technology.

Zeta Energy and Stellantis N.V. announced a joint development deal to advance battery cell technology for electric vehicle applications that will develop lithium-sulfur EV batteries with gravimetric energy density that can achieve a volumetric energy density comparable to today’s lithium-ion technology. The batteries are targeted to power Stellantis electric vehicles by 2030.

“The combination of Zeta Energy’s lithium-sulfur battery technology with Stellantis’ unrivaled expertise in innovation, global manufacturing and distribution can dramatically improve the performance and cost profile of electric vehicles while increasing the supply chain resiliency for batteries and EVs,” Tom Pilette, CEO of Zeta Energy, says in a news release.

The batteries will be produced using waste materials and methane that boasts lower CO2 emissions than any existing battery technology. Zeta Energy battery technology is intended to be manufacturable within existing gigafactory technology and would leverage an entire domestic supply chain in Europe or North America.

The technology can lead to a significantly lighter battery pack with the same usable energy as contemporary lithium-ion batteries. The companies believe this will enable greater range, improved handling and enhanced performance. The technology has the potential to improve fast-charging speed by up to 50 percent, which can make EV ownership easier.

Lithium-sulfur batteries are expected to cost less than half the price per kilowatt of current lithium-ion batteries according to a news release. Zeta has more than 60 patents on its proprietary lithium-sulfur anode and cathode technologies.

Lighter and more compact EV batteries have become an important design goal for vehicle designers and manufacturers. This objective is similar to what General Motors is doing with prismatic cell technology with LG Energy Solution.

“Our collaboration with Zeta Energy is another step in helping advance our electrification strategy as we work to deliver clean, safe and affordable vehicles,” Ned Curic, Stellantis chief engineering and technology officer, says in the release. “Groundbreaking battery technologies like lithium-sulfur can support Stellantis’ commitment to carbon neutrality by 2038 while ensuring our customers enjoy optimal range, performance and affordability.”

Last year, Zeta Energy announced that it was selected to receive $4 million in federal funding for the development of efficient electric vehicle batteries from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program.
