However one thing to keep in mind is that while extremely promising, green hydrogen is usually more expensive than gray hydrogen.

So without policy support it's hard to make green Hydrogen happen. Unfortunately the US is still struggling to have any significant climate policy at all (thanks Joe Manchin).
