Iogen announces new drop-in cellulosic biofuel

January 24, 2014, Ottawa, Ont. – 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 U.S. 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 U.S. EPA’s Landfill
Methane Outreach Project Conference in Baltimore.
