How about choosing a fuel made from bio-gas instead of crude oil?
Rosemary Ostfeld, contributor to Green Patent Blog, published a story today that describes a process invented by Primus Green Energy of Hillsborough, New Jersey that converts biomass into 93-octane fuel.
The company currently produces several kilograms of gasoline per hour at a pilot plant in Hillsborough, New Jersey.

Under construction is a $12 million continuous demonstration plant which will produce 30 kg of gasoline each hour.
In 2013, Primus Green Energy expects to begin construction on a commercial plant expected to produce as much as 4.5 million gallons of bio-gasoline annually.
Even if oil prices drop, Dr. George Boyajian, Primus Green Energy’s VP of Business Development, says that the biomass conversion process is efficient enough to produce a greater yield, making biomass fuel competitive and an attractive long-term alternative.
