E-fuels, coal, gas, oil, wood. There I did it.
Wood is renewable and literally grows without effort. Pretty darn good.
Gas and oil have much, much better energy density (by volume) which is a big deal for transportation uses. Pretty darn good.
Hydrogen is bested by other fuels in every category. It likes to leak directly through container walls, you can't transport it economically, it has low energy density (by volume) even when you put it in a pressure vessel which is basically required to have any energy storage wroth speaking about, and on top of all that it is expensive to produce. Hydrogen sucks as a fuel. It's why it isn't used hardly anywhere despite the technology to use it existing for decades.
Wood is only good if you produce it regionally. Cutting down forrests to produce wood pellets for heating in Western Europe is very bad. Wood is most of the time not as sustainable as one might think.
Oil and gas are used as much as they are for a reason, but it's also the reason why we face an ecological tragedy.
It's not that hydrogen is perfect, but it has more of a place in the future than the other ones.
That and wood isn't the best fuel overall. It's okay for very local burning, but as a source of more concentrated energy just about all other fuels are better. There's a reason you don't see wood-powered electricity plants anywhere.
