JCB is unveiling its first zero-carbon emissions hydrogen-fuelled engine at the Conexpo 2023 show in Las Vegas.
The UK-headquartered company said a £100m investment saw 100 engineers at its Derbyshire factory working on the engine for more than a year.
It already powers a prototype backhoe loader and a telescopic handler.
The company claims to be the first construction equipment maker to develop a fully working hydrogen-fuelled engine.
It has developed a mobile hydrogen refuelling unit to get hydrogen to work sites.
