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.Let us, therefore, add “LIQUID HYDROGEN”³ to the subdivisions of uses of HYDROGEN.
