Is hydrogen, rather than electric, the future for big-engined machinery? I visit JCB to find out

I visit JCB to see first hand the work they are doing as they look for alternatives to diesel power for their heavy duty machines. They already sell fully electric machines and have a hydrogen fuel cell excavator under development but they have recently been working on making their diesel engines run on hydrogen instead and have been amazed by the results. I visit the factory to find out more.. This video was created with the support of: Follow me on
