Supercheap hydrogen. For MIT Solve
Abstract. Supercheap hydrogen for chemistry and artificial fuel production. Zero-carbon and hazard free domesticaly and distributaly. (1) Al2O3 + 3 H2O = 2 Al(OH)3, heating and pressure 10 - 100 bars. (2) 2 Al(OH)3 + k * (H2O = H2 + 0.5 O2) + Al2O3 + 3 H2O. All reagents are circular here, so they are practically free. Total energy consume is energy for the water thermolysis only, and at k = 1, being a heat of 242 kJ/mol H2 at T = 500 C. vs. 2500 C conventional. Because renewable energy of solar and wind can be cheapened in order of magnitude down to USD 0.004 / kWh or less [1], H2 product can be 242 kJ * 10^6 * 0.004 /3600 sec./2 = USD 133 /ton H2, OPEX.
