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.

Does not seem to be a viable long term application. There is always residual buildup in electrolysis till the system eventually breaks down

hard to take a statement about overcoming bariers, when the actual publication is paywalled, the abstracts are posy only mixed with nosebleed level chemistry, and basics like watts/kg storage and expected life cycle are not included. Oh and exactly where the mythical hydrogen generation, transportation and storage infrastructure is going to come from. Meanwhile sodium batteries are quietly bieng introduced, at scale.

edit: article apears to describe a way to provide local level "tankage" rather than bulk storage

I do hope that suddenly in 2030, something in the hydrogen invested countries like Japan happens where they suddenly flood the market with step changing tech that will complement exisiting LFP/ Sodium ion and other tech especially for longer duration storage (weekly to monthly may be not seasonal but still useful).

It feels like they are working slowly and steadily on the tech and have been doing it since many decades although they never planned to scale it like China did with batteries or solar for numerous reasons beyond the tech folk's capacity

I’m partial to sticking them to carbon atoms for storage (methane).

How would this compare?

Another day, another new battery innovation that probably will never see mass production.
