E-fuels producer HIF Global on March 11 said it has been awarded the first U.S. approval for an e-fuels pathway.

E-fuels, or electrofuels, are synthetic fuels made with renewable energy resources. The Houston-based company develops projects focused on producing fuels with renewable energy, including electrolytic hydrogen, and recycled CO2.

Granted under the California Air Resource Board’s Low Carbon Fuel Standard (LCFS) Program, the Tier II Design Pathway Certification includes e-sustainable aviation fuel, e-naphtha and e-diesel as opt-in fuels that allow producers to apply for and generate credits for e-fuels, HIF Global said in a news release.

“E-Fuels are synthetic hydrocarbons that seamlessly integrate with today’s existing infrastructure and engines,” said Meg Gentle, executive director of the HIF Global Board. “This LCFS certification underscores the growing demand for e-Fuels in the U.S. and globally, which could reach more than 250 mtpa [million tonnes per annum] by 2035, providing opportunity for over $1 trillion in potential capital investment in new facilities to produce the fuels, including HIF Global’s 1.4 mtpa e-Fuels project in Matagorda County, Texas.”
