First hydrogen locomotive started working in Poland.
Not trying to start a fight or anything, but don’t we still ‘need’ to burn a lot of coal to fuel electricity? Renewables haven’t gotten close to pushing the necessity of coal away yet, no? Why not alternatives like this in some places to offset the need for electricity?
Hydrogen doesn’t exist randomly in a well or something it has to be created by using electricity - and that transformation is very inefficient if you then use the hydrogen in an inefficient way to power an engine instead of just using the electricity directly
That argument that energy is coal-heavy actually counts against hydrogen…
Hydrogen powered stuff only makes sense when electric isn’t an option like for planes that just can’t carry heavy batteries
Apparently, some hydrogen does come out of the ground like methane: https://www.weforum.org/agenda/2023/09/white-hydrogen-deposit-france/ but I assume it’s not abundant enough to make a difference
You don’t have to use electricity to make hydrogen! You can make it from methane! But yeah, it’s probably even worse than a diesel engine when it comes to CO2 emissions…
The issue to me in term of effeciency is that the production of hydrogen needs electricity, the movement of it needs electricity, the storage and pumping of it needs electricity, and so on. I’d rather see all that electricity in the process simply be moving the vehicle. Though lugging batteries along is an issue in it’s own.
Nuclear is the energy source that scares everyone but that is actually the most viable option to power the world until renewable becomes the dominant one.
Thorium has been the best solution all along but it can’t be weaponized so countries have been ignoring it for decades until recently
