Remember that many many countries on the planet have NO intention of phasing out fossil fueled engines. The majority of JCB's business is in the developing world hence their efforts to develop this method of powering machines.I can’t see JCB investing millions of pound to develop a hydrogen engine , if it isn’t going to comply with future regulation
My sister in law is a chemical engineer for one of the consultancies involved in the work, it will be nearly 2 years since she told us about it. Sounds really interesting.There was a program on radio 4 about it the other week. There’s a big government funded trial going on somewhere up on one of the Scottish Islands. They’re using solar and wind power to produce hydrogen which is then stored and used to heat the homes and produce more electricity when demand was higher. It was also there transported to the docks and use in generators to charge the ferry’s. Long term hydrogen will be the way forward because you can store it for when the demand is highest and no need for a massive network of cables. It can also be imported and exported much easier than electricity.
