Fuck hydrogen. Its a fake green product so oil companies can transition as slow as they want while still keeping their strangle hold on our society.
It depends a lot on where the hydrogen is sourced from. Hydrogen that is generated from electrolyzers using renewable power is completely green (and funny enough, called Green Hydrogen), and is a good way to store excess energy from solar and wind.
Oil companies however want to market hydrogen from drilling and refining, which is dirty as hell.
It's an important differentiation to make though. Hydrogen is not inherently bad and will have plenty of green applications. We just have to make sure it's coming from the right places.
Is it really that good of a storage method, though? The round-trip efficiency is quite bad when compared to other methods of storage.
Acording to this paper/article, its better than technologies such as batteries, but the study isn't the most comprehensive and doesn't consider things like pump hydro.
It's hard to assess the validity of those claims as the article doesn't bring any numbers and the paper itself is paywalled. As the fossil fuel industry is pushing hard towards wedging in hydrogen as a means of keeping themselves alive for a while longer, it's vital to be able to assess the actual claims, lest they are just planted there by the fossil fuel industry.
