About

Prometheus Fuels is a clean energy company founded in 2019 by Rob McGinnis and headquartered in Santa Cruz, California. The company has developed a proprietary electrochemical process to capture carbon dioxide directly from the atmosphere and convert it into hydrocarbon fuels — including gasoline, diesel, and jet fuel — that are fully compatible with existing internal combustion engines and aviation infrastructure. Because the carbon in the fuel was drawn directly from the air, the combustion of Prometheus fuels releases no net new CO2, making them carbon-neutral or, depending on the energy source used in production, potentially carbon-negative.

About

Electric Hydrogen is a Natick, Massachusetts-based clean energy company founded in 2020 by Raffi Garabedian (former CEO of First Solar) and David Eaglesham. The company designs and manufactures large-scale industrial electrolyzers — systems that use electricity to split water into hydrogen and oxygen — intended to produce green hydrogen at the cost and scale required to decarbonize heavy industries. Electric Hydrogen's core product is a 100MW electrolyzer plant that represents one of the largest single electrolyzer systems commercially available, designed for industrial customers in steel, ammonia, chemicals, and fuel production who need hydrogen at massive volumes.
