[Richard Tarara <rtarara@saintmarys.edu>]

There is a link at the bottom of the ice article
https://www.vox.com/energy-and-environment/2018/2/16/16926950/hydrogen-fuel-technology-economy-hytech-storage
concerning developments that might possibly bring hydrogen back into the 
discussion of energy storage from other renewables like wind and solar 
that is worth a look if you are so inclined.
