Shell First to Sell Gasoline Blended With Advanced Biofuel

HOUSTON, June 10 /PRNewswire-FirstCall/ -- From today, customers at a Shell
service station will become the first in the world to fill their tanks with
gasoline containing advanced biofuel made from wheat straw.

For one month starting June 10, the regular gasoline purchased at a Shell
service station in Ottawa, Canada will contain 10% cellulosic ethanol. The
biofuel is produced locally from non-food raw materials at Iogen Energy
Corporation's demonstration plant, using advanced conversion processes. Iogen
and Shell are partners in the plant, which now produces 40,000 liters of fuel
per month.

Cellulosic ethanol, as an end fuel, is identical to ethanol but it can offer
up to 90% less lifecycle CO2 emissions than gasoline. It is a key part of
Shell's strategic investment and development program in sustainable biofuels.

"I am excited we are leading the pack in cellulosic ethanol production
technology and, with this event, showing what is possible in the future," said
Dr. Graeme Sweeney, Shell Executive Vice President Future Fuels and CO2.
"While it will be some time before general customers can buy this product at
local service stations, we are working with governments to make large-scale
production economic."

"We're proud of this world-first," said Brian Foody, Chief Executive Officer
of Iogen Corporation. "Building a demo plant is one thing but you then need to
go through the process of operating the new technology at scale, learning,
modifying and lowering costs. With the volumes we're producing today, we're
confident about the future."
