Abstract
A hydrogen fuel, sustainable, closed clean energy cycle based on green chemistry is presented for large scale implementation using a cost effective electrolytic cell. A chemical reaction between salinated (sea) or desalinated (fresh) water (HO) and sodium (Na) metal produces hydrogen (H) fuel and sodium hydroxide (NaOH) byproduct. The NaOH is reprocessed in a solar powered electrolytic Na metal production plant that can result in excess chlorine (Cl) from sodium chloride (NaCl) in sea salt mixed with NaOH, used to effect freezing point lowering of seawater reactant for hydrogen generation at reduced temperatures. The method and molten salt electrolytic cell enable natural separation of NaCl from NaOH, thereby limiting excess Clproduction. The recovered NaCl is used to produce concentrated brine solution from seawater for hydrogen generation in cold climates, or becomes converted to sodium carbonate (NaCO) via the Solvay process for electrolytic production of Na metal without Clgeneration.
