Fuel Freedom is running a smart national campaign, enlisting both free market advocates and environmental organizations to the cause. “Methanol burns cleaner than gasoline,” says Hollander. “It would make a big improvement in air pollution.” With bi-partisan backing, the Open Fuel Standard Act is also making its way through Congress. The law would require automakers to produce cars that can run on multiple fuels, including methanol. “Right now the auto companies could produce flex-fuel vehicles any time they want,” says Hollander. “Their answer is always that they’ve tried before and nobody wanted to buy them.”
Green diesel is produced through hydrocracking biological oil feedstocks, such as vegetable oils and animal fats.   Hydrocracking is a refinery method that uses elevated temperatures and pressure in the presence of a catalyst to break down larger molecules , such as those found in vegetable oils , into shorter hydrocarbon chains used in diesel engines.  It may also be called renewable diesel, hydrotreated vegetable oil  or hydrogen-derived renewable diesel.  Green diesel has the same chemical properties as petroleum-based diesel.  It does not require new engines, pipelines or infrastructure to distribute and use, but has not been produced at a cost that is competitive with petroleum .  Gasoline versions are also being developed.  Green diesel is being developed in Louisiana and Singapore by ConocoPhillips , Neste Oil , Valero , Dynamic Fuels, and Honeywell UOP   as well as Preem in Gothenburg, Sweden, creating what is known as Evolution Diesel.
