I've said it before and I'll say it again: most new hydrogen technology is snake oil.

Its main source right now is as a byproduct to petrochemical processing, so a lot of the motivation behind it is really about maintaining these production lines, rather than "going green".

Some things do require hydrogen, eg science applications. Hydrogen can be made using green electricity, but the energy cost is incredibly high. In order to fulfill just the things that require hydrogen, where there is no other alternative, we would need 3x the global renewable capacity solely dedicated to hydrogen production. If we start adding mass transport into that mix, or things like this hydrogen heating system, then we're only exacerbating the problem.

We need our renewable electricity to power things that already use electricity. We don't have enough capacity to be pouring it away into all the potential uses for hydrogen - which are often far less efficient. You lose so much energy creating hydrogen (as well as losses due to leaks) that you may as well just power it with electricity directly.

This is anti-hydrogen propaganda. It is basically a marketing spiel for the battery industry. In reality, hydrogen is going to power nearly all transportation, mainly because batteries are not a sustainable solution.

And the notion that we can't build enough renewable energy capacity is a classic climate change denial argument. People who say this are unknowingly (or sometimes knowingly) trying to get everyone back onto fossil fuels.

I can't tell if you're trolling or not. Well done.
