Iogen Corporation announced it has developed and patented a new method to
make drop-in cellulosic biofuels from biogas using existing refinery assets and
production operations.
The company estimates there is refining capacity in place to incorporate 5-6
billion gallons per year of renewable hydrogen content into gasoline and diesel
fuel. Iogen will initially commercialize the approach using landfill biogas, and
then expand production using biogas made in the cellulosic ethanol facilities it
is currently developing.
The production method involves processing biogas to make renewable hydrogen
and incorporating the renewable hydrogen into finished fuels in selected
refinery hydrogenating units.
The overall greenhouse gas emissions are reduced by more than 60%, meeting
the threshold for cellulosic biofuel in the USA. Iogen said it is actively
consulting with the EPA and CARB to gain pathway approval for cellulosic RIN and
LCFS credit generation.
“Biogas is produced today from landfills, wastewater treatment plants, waste
digestion facilities, and farm digesters with well-proven technology,” says
Patrick Foody, Iogen’s Executive Vice President, Advanced Biofuels. “We can now
take biogas and make specification gasoline and diesel with renewable content
using well-proven existing refining operations. It is a win for
everybody.”
The company says it is planning to use the technology in association with two
large-scale US cellulosic ethanol plants it is developing, resulting in
increased overall cellulosic biofuel yields per unit of feedstock, lower unit
capital costs, and lower water usage per unit of biofuel production. The company
made the announcement at US EPA’s Landfill Methane Outreach Project Conference
in Baltimore.
