Great to see the advances happening in Hydrogen storage and transport! 90C temperatures for storage are easily achieved and such an improvement over 300-400c for storage.

I do wonder about the efficiency though as that has not been clearly mentioned in the article though they are alluding to it being more efficient than using liquid electrolytes for Hydrogen transport.

This will highly depend on the insulation and the duration of storage.

Likely not useful for your personal car that stands a week in sunlight but maybe for s. th. Like public transportation

I don’t think anyone believes hydrogen to be relevant for ground transportation anymore.

But for industry, grid energy storage (perhaps longer term, paired with existing gas power plants, to deal with dunkelflaute) and perhaps some roles in sea and air transportation… there are plenty of areas where efficient hydrogen storage would be useful.

		For stationary storage at scale, underground storage as a compressed gas would be hard to beat, especially if salt formations are available for solution mined caverns.
