Liquid hydrogen

It would be helpful were it economically acceptable to liquefy hydrogen. However, methanol is a liquid and could be written CH4O. The Nobel Laureate, George Olah along with two co-enthusiasts, published a book (2006) entitled “A Methanol ECONOMY”.3 If the methanol is synthesized from hydrogen and CO2 from the atmosphere, burning it as a fuel would merely replace in the atmosphere the CO2 taken from it and in the synthesis of the methanol. , therefore, add “LIQUID HYDROGEN”3 to the subdivisions of uses of HYDROGEN.
