For seasonal storage, I believe that the most promising technology would be catalytic conversion of co2 to methanol. Methanol is liquid at ambient temperature and much safer to store than hydrogen. There is a class of fuel cells that can directly convert methanol back to electricity. Reply reply. chabybaloo.
