Methods for producing hydrogen gas from organic substances. According to the methods, hydrogen is produced from an electrochemical reaction of an organic substance with water or a base. The instant methods permit the production of hydrogen at lower operating voltages or lower operating temperatures relative to water electrolysis. Operable organic substances include alcohols, ethers, carboxylic acids, aldehydes, and ketones. In a preferred embodiment, hydrogen gas is produced from an electrochemical reaction of methanol in the presence of a base such as NaOH or KOH. A process for producing hydrogen gas from a reaction of an organic substance and a base with a recycling of a carbonate or bicarbonate by-product and regeneration of the base. In one embodiment, reaction of an organic substance and a base produces hydrogen gas and a metal carbonate. The instant invention provides recycling of the metal carbonate by-product. In another embodiment, a bicarbonate by product is formed by a hydrogen producing reaction of an organic substance and a base and bicarbonate recovery occurs by heating the bicarbonate to form a carbonate and recycling according to the instant carbonate recycling process. |
