Ditch the Batteries: Off-Grid Compressed Air Energy Storage

Have we figured out a good way to store Hydrogen that avoids leakage? I've heard that even thick-walled stainless steel vessels can leak ~1% a day.

Yeah, you coat the cell interior with platinum. Adds significantly to the cost and complexity of production though.

and use platinum in the fuel cells. the real-world problems are pretty obvious though - Pt is worth stealing and it's expensive 'cause there aint that much of it so you can't expect to use 100x as much as now and not expect the price to change. FC's are niche. Batteries won.
