Howard ...I think the draw of hydrogen is to flatten the intermittency of renewables .......turn the leccy into hydrogen that can then be used when we need it rather than when it's sunny or windy ... there's the ability to store energy in quantities that may never practically be reached with batteries (and in dumb metal tanks without the eventual toxic material disposal issues) .... some sci-fi improvement to battery storage levels will be needed before people stop thinking about hydrogen.

Exactly. Electricity storage aka batteries is expensive... 14K for a pair of Tesla Powerwall units?
