HC Deb 15 January 1974 vol 867 cc37-8W
Mr. Dalyell

asked the Secretary of State for Trade and Industry what discussions he has had with airlines using British airports on the use of JP 4 as an aero-engine fuel ; and if he will make a statement.

Mr. Onslow

None. JP 4 is not available at British airports and the Civil Aviation Authority has issued initial guidance to British airlines about procedures to be followed in the event of JP 4 being uplifted elsewhere.

Mr. Warren

asked the Secretary of State for Trade and Industry what research is being conducted by Her Majesty's Government into the use of hydrogen as a fuel for aircraft.

Mr. Michael Heseltine

Some research has been done with Her Majesty's Government's support on the use of alternative fuels, such as liquid hydrogen and methane, for aircraft engines. Combustion in a conventional gas turbine is practical, but the handling, safety and storage problems of liquid hydrogen are acute.
