That will not have any significant impact on bridging cost differentials between bioethanol and fossil petrol.
Hydrogen can be created by using bioethanol, which provides a zero emission fuel right up the line.
Bioethanol comes from a field crop and is essentially an agricultural raw material.
The point to remember is that, although bioethanol is a pathway fuel, it is also a long-term fuel for a hydrogen economy.
It has a sister called bioethanol derived from wheat, potatoes and sugar beet.
However, if one introduces a tax break to allow cars to run on bioethanol one would have fundamentally to re-engineer the engine of each car.
In other cases, there will be an opportunity to use existing co-products for new purposes—for example, the use of wheat straw to produce bioethanol.
Studies have been carried out and several international seminars held, on the use of bioethanol as substitute for lead as an octane booster in petrol.
