Very interesting. More reversible rusting.
Interesting that it comes into play both for hydrogen storage and chemical batteries
BTW, the source article linked from the article in RC’s post is better. The GNN version gets some basics wrong. For example it says the station will be made up of 50 washer/dryer sized modules. That’s not what the source article says at at all (and the small size was what I thought was most surprising). Actually each module has 50 cells, the the source article says nothing about the number of modules at the station.
