Prediction: Green hydrogen production will be cheaper more quickly than many expect. Meanwhile, most articles still refer to it as prohibitively expensive even after the IRA production tax credits. they will be surprised. https://www.hydrogeninsight.com/innovation/cheaper-hydrogen-us-start-up-demonstrates-iridium-free-pem-stack-that-will-nearly-halve-cost-of-electrolysers/2-1-1371240
Cheaper hydrogen? | US start-up demonstrates iridium-free PEM stack that will 'nearly halve' cost of electrolysers | Hydrogen news and intelligence

H2U Technologies has replaced the expensive catalyst used in proton-exchange-membrane machines with ‘inexpensive and abundant’ materials

@justinmikulka Most of the criticisms I have seen around hydrogen cost aren't necessarily around production but around energy by volume, storage/transportation, and lifecycle efficiency.

Are there any developments ready to address those issues?

@thomas Depends on the application. For steel, LDES and replacing existing dirty H2, those aren't issues, imo. For aviation and shipping they certainly are. However, they are engineering problems that can be solved.

@justinmikulka I get steel. But storage (also lifecycle efficiency) is critical for LDES?

It has been really hard to store H2. (in a way that can be easily repeatable) LDES may end up being case by case with hydrogen.

@thomas Hydrogen (like crude oil and natural gas) has been stored in salt caverns for decades. The US has ample salt deposits for this. A real advantage over china who does not.

@justinmikulka yes, but Salt Caverns are not easily repeatable projects (at least that is my understanding)

They will be part of the solution, but will most likely be a case by case. Which, I guess, we could probably say about everything.
