It would be helpful were it economically acceptable to liquefy hydrogen. However, methanol is a liquid and could be written CH(4)O. 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 CO(2) from the atmosphere, burning it as a fuel would merely replace in the atmosphere the CO(2) taken from it and in the synthesis of the methanol. Let us, therefore, add "LIQUID HYDROGEN"(3) to the subdivisions of uses of HYDROGEN. Copyright (C) 2010, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
