OCAÑA

The first aircraft to use only a hydrogen battery for power in the air has successfully completed a test flight. The US company Boeing said that the flight, in Ocaña, central Spain, was “a historical technological success for Boeing [and] full of promises for a greener future”.

The aircraft, which is capable of carrying two people and has a wingspan of 16 metres (52ft), flew at 100km/h (62mph) for 20 minutes. Hydrogen power involves fuel cells using the energy produced from the transformation of hydrogen and oxygen into water. According to Boeing, it provides a cleaner and renewable energy resource because it produces only water vapour as waste.

The director of the Boeing research centre at Ocaña, Francisco EscartÍ, said that hydrogen batteries could become the main source of energy for small aircraft, but that they were unlikely to power larger passenger aircraft. “The company will continue to explore their potential as well as that of all durable sources of energy that boost environmental performance,” Mr EscartÍ said, adding that the test plane had the advantage of “not making any noise”.

Several carmakers, including General Motors, Nissan and BMW, are working on the development of hydrogen-powered cars.
