Alkaline gas storage is a reversible chemical process which can bind certain gasses, including carbon dioxide, [[carbon monoxide], sulfur dioxide, and hydrogen sulfide in an aqueous solution of sodium hydroxide which can be easily stored either as the solution or as the solvated solid. Either material will react with an acid (such as acetic acid) to produce sodium acetate and the original gas, essentially allowing the gas to be "stored' as a liquid or a solid. Once pressurized gas handling is available, this process is less practical.
