Why JCB thinks hydrogen is the best alternative to diesel for heavy machinery, farming and HGV fleet

JCB are actively investigating the best alternative to diesel for powering their machines in this new age of alternative fuels to help combat climate change. They have discovered batteries are okay for light duty machines but not for the heavier load machines like excavators and tractors. Hydrogen fuel cells are also being tested but their cost is prohibitive, so JCB investigated the possibility of swapping diesel for hydrogen in their regular diesel engines and liked what they discovered..
