Aemetis to launch Zero Carbon renewable fuel plants following US Patent award

Aemetis’ exclusively licensed technology for the production of below zero-carbon renewable fuel has been awarded US Patent No. 10907184.

With the US Patent, the company can now launch Aemetis ‘Carbon Zero’ production plants to commercialise the technology.

Aemetis’ Carbon Zero plants are designed to convert below zero carbon feedstocks (waste wood and agricultural waste) and renewable energy (biogas, RNG, solar) into energy-dense liquid renewable fuels. The company expects that such renewable fuels, when used in hybrid electric vehicles or other vehicle engines, will have a ‘below zero carbon’ greenhouse gas (GHG) footprint across the entire lifecycle of the fuel, based on the Argonna National Laboratory’s GREET model.

Eric McAfee, chairman and CEO of Aemetis, said: “We are naming these projects ‘Carbon Zero’ to reflect our mission to reduce GHGs. Wood is partially comprised of CO2 from the air.

“Agricultural waste wood has a below zero carbon intensity as a fuel by avoiding GHG emissions, since waste wood is usually burned in the field or breaks down into harmful methane emissions.

“By combining below zero carbon waste wood with zero-carbon renewable energy obtained from solar, hydroelectric and biogas sources, Aemetis is transforming these sources of renewable energy into zero-carbon renewable fuels that work with existing engines, as well as range extender generators used in electric cars or trucks as long-haul and local delivery vehicle adopt electric drivetrains to improve emissions, fuel efficiency, and performance.”

The first Carbon Zero production plant – Carbon Zero 1 – is planned for Central California on a former Army ammunition production facility. It will extract sugars from waste wood and process the sugar into renewable fuel.
