Hydrogen fuel cell cars (2020)
Hydrogen almost certainly won&#x27;t go anywhere, in my opinion.<p>* The efficiency compared to battery tech is horrendous.<p>* Hydrogen is effectively a storage technology -- we have to generate it and compress it. Which combined with the above means that charging a hydrogen car will always be more expensive than putting the same amount of usable energy into a battery powered car.<p>* Let&#x27;s not forget that the cheapest way of generating hydrogen is from fossil fuels. Electrolysis is very inefficient.<p>* Any concern there might exist for the effect on the electrical grid coming battery powered cars multiplies for hydrogen due to the inefficiency.<p>* You need a large infrastructure to produce and distribute it.<p>* It&#x27;s a huge chicken and egg problem -- a hydrogen car needs hydrogen, and there&#x27;s nowhere convenient right now to get it from.<p>* In the end, a hydrogen car is ultimately electric. What is more convenient, having a car that can be plugged into an outlet, or a car that needs an extremely specialized hydrogen station?<p>IMO the only excitement from hydrogen is for fossil fuel companies, because that&#x27;s what the vast majority of it is made from, and because it&#x27;d be a fairly natural fit into their existing infrastructure.<p>There may be some niches where hydrogen could be the better solution -- hydrogen trucks might be viable because there you can have well defined routes, and trucks have a weight limit which may not play well with batteries. But for normal cars I don&#x27;t really see it.
