"exposed CO2 to catalysts and then electrolysis forming sodium formate powder... highly efficient conversion... does not corrode storage tanks... also designed a refrigerator-sized fuel cell that uses a liquefied version of the stored power... more promising than hydrogen (storage problems) and methanol (toxic fumes)... homes, heavy industry"
