In reply to the discussion: Intermittency Of Renewables?… Not So Much [View all]BlueStreak
(8,377 posts)63. Hydrogen efficiency
I don't know that the process of making hydrogen is that much less efficient than other storage schemes. You lose energy in all of these systems. Maybe hydrogen is a bigger loss than others, but it has a big advantage. The stored hydrogen can be used to power fuel cells, so there can be a dual purpose in converting excess energy to hydrogen. That would seem to offset the disadvantages of energy loss somewhat. In other words a storage medium that has multiple uses is intrinsically more valuable than a medium that can only really be used to put energy back into the grid.
