HC Deb 21 January 1987 vol 108 c571W
Mr. Knowles

asked the Secretary of State for Energy what research has been carried out into the feasibility, cost-effectiveness and environmental implications of using bioethanol as a substitute for lead in petrol; and if he will make a statement.

Mr. Buchanan-Smith

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. All have concluded that there are cheaper alternatives. However, the energy technology support unit at Harwell is carrying out a detailed study on the cost of production of ethanol from various biomass sources. Its report is expected to be published towards the end of this year.
