Summit Carbon Solutions on Feb. 5 said it entered an arrangement with electrofuels (eFuels) producer Infinium for a supply of up to 670,000 metric tons of CO2 annually at a proposed eFuels facility in North Dakota or South Dakota.

The proposed facility would open more market opportunities for U.S. ethanol producers and farmers in the Midwest, Summit said in a news release.

“As demand for eFuels continues to rise, it is essential to secure reliable and scalable CO2 sources,” said Infinium CEO Robert Schuetzle. “Summit’s infrastructure would supply the CO2 needed to scale production and advance eFuels as a key part of America’s energy future.”

Made by combining captured CO2 with green hydrogen, eFuels are used in the aviation, shipping and heavy transport sectors.

“CO2 is a commodity with growing value, and Infinium’s eFuels technology is an important piece of the puzzle,” said Summit Carbon Solutions CEO Lee Blank. “By providing a reliable CO2 supply, we’re helping unlock opportunities that support domestic energy production and economic growth.”
