AP NewsIndia launches first hydrogen-powered train built in the country to expand clean energy on railwaysIndia has introduced its first hydrogen-powered train designed and built in the country in a move to expand clean energy use on its rail network.And where do they get the hydrogen???
Fossil fuel… But you really have to dig to find where they admit it.
Last time this came up it was buried in the documentation about how wind and solar don’t provide enough.

In all fairness hydrogen is good battery store for green energy too.

it’s awful. WTF. Takes huge energy to keep it cryogenically stored.

Where are you getting that it needs to be “cryogenically stored”? It’s mostly stored as compressed gas.
The main problem with hydrogen is stores only 40% but with green energy surplus and 40% is better than 0% and hydrogen store systems are quite cheap and mature/simple so still relevant in highly developing areas like those of India.
It’s still a good battery for these specific niches so I wouldn’t discount this as some big oil propaganda

Containment of gaseous hydrogen is problematic because H2’s molecular size is tiny, so it seeps through gaps that would contain other gases. So you need an especially robust container. It’s also highly reactive.
No idea what your 40% comment was about, it’s incomprehensible.

They’re the most powerful force pushing hydrogen, so it’d be entirely reasonable to at least consider the possibility.

Only 40% of energy is stored and 60% is wasted in conversation.
Yes everyone’s aware hydrogen is small, no one’s contesting this but you still don’t need freeze store just as you said proper containers. The issue you mostly hear of hydrogen leaking is from dispensaries like hydrogen gas stations not long term static containers.
