British driver who broke sound barrier sets new speed record

Twenty years ago, Green also set a world land speed record for a diesel vehicle in the JCB Dieselmax, attaining a speed of over 350mph (563km/h).

The new record, set in JCB's Hydromax vehicle, surpassed the previous official hydrogen combustion title set in 2004 (185.5mph) by more than double the speed.

"Setting a world land speed record with hydrogen power, 20 years after Dieselmax, is a huge privilege. This record is a huge achievement by a world class team and superb technology," Green said.

Last month, Green said his wife's encouragement was crucial in persuading him to accept the challenge after getting a call from JCB chairman Lord Anthony Bamford.

Lord Anthony said: "Twenty years ago we came to Bonneville with JCB Dieselmax and showed what British engineering could do with diesel power. Today we have done it again - this time with engines powered by hydrogen."
