Electrolysis is extremely energy intensive. While it’s possible, it isn’t anywhere near as scalable or efficient as electric trains or busses, which can simply be powered directly from the grid. No need for expensive hydrogen or rare, toxic, and politically tenuous elements for batteries.
Okay, great, I love trains and trolleybuses. I’m talking about alternatives for BEV vehicles, where trains and trolleybuses can’t be used or are impractical for whatever reason.
I have said repeatedly almost everywhere my comments can be found that most funding should go to public transit infrastructure, but I think a niche exists for vehicles which do not have constant or reliable access to the electrical grid, and I think that green hydrogen FCEV is the best choice for that niche. I don’t think it really matters how inefficient electrolysis is, because the hydrogen is functionally free.
Hydrogen is not green. It’s a byproduct of the fossil fuel industry. What we need is bicycles and electric trains.
Green hydrogen is green. That’s what the green part of it means. Fossil fuel derived hydrogen is called blue hydrogen.
What is the source of green hydrogen?
Sunlight (Solar PV) and water. Water is split into oxygen and hydrogen gas using electrolysis.
