New kind of catalysts for low temperature water thermolysis.

(1) Al2O3 + 3 H2O = 2 Al(OH)3, heating and pressure 10 - 100 bars. 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 = > (150 + k * 242) / (450 + k * 54) = 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, (2) Catalyst: CO2 + H2 = HCOOH - formic acid. Joint target reaction: HCOOH + 0.4 * (H2O = H2 + 0.5 O2) + CO2 + H2. dH = 32 + 0.4 * 242 = 128 kJ. dS = 214 + 0.4 * (131 + 102 - 180) = 234. dG = 128 - 234 * T 274 C. Because all reagents here are circular and practically free, so OPEX cost of the hydrogen is about USD 70 /ton H2. (3) Catalyst is 0.5 * N2 + 1.5 * H2 = NH3, is joined with 0.365 mol of the water splitting, it gives a h...

https://(Fresh look on Wind Power Generation – Upgraded, 25/02/2019, David Judbarovski, 2019 AIChE Annual Meeting (ISBN: 978-0-8169-1112-7), https://www.aiche.org/proceedings/people/david-judbarovski } Breeding investment allows by credit for a first power plant in five steps to invest and build some tens analogous power plants. . So OPEX is negligible vs. CAPEX, can be full cost of artificial intermediary fuel for 100% off-grid electricity by 2.5 cent/kWh. For housing such autonomy can be provided by local fuel-in-electricity substations. Autonomous supply can be paralleled by much cheaper direct grid supply.

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 = > (150 + k * 242) / (450 + k * 54) = 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.

Al2O3 + 2 NH3 as a new kind of catalysts. Corrected.

Al2O3 + 2 NH3 as new kind of catalyst - Corrected. David Judbarovski, systems engineering, principle inventor. judbarovski.blogspot.com, judbarovski@gmail.com April 12, 2026 (1) Al2O3 + 2 NH3 = 2 AlN + 3 H2O. dH = 406 kJ, dS = 181 J /mol * K. Because all reagents here are circular, they are practically free (see reaction (2) for the water thermolysis). (2) (2 AlN + 3 H2O) + k * (H2O = H2 + O.5 O2) + (Al2O3 + 2 NH3), T > (k * 242 – 406) * 1000) / (k * 54 – 181). If k = 1.0, the reaction (2) is s at T = 1000 C. for k = 0.5, T > 720 C. OPEX cost of the hydrogen product practically is equal to a cost of energy consumed. It is 242 kJ/mol = USD 242 * 1.1 / 2 = USD 133/ton H2. References. 2021 Annual Meeting.

Al2O3 +2NH3 as a new kind of catalyst

(1) Al2O3 + 2 NH3 = 2 AlN + 3 H2. dH = 274 kJ, dS = 181 J /mol * K. Because all reagents here are circular, they are practically free (see reaction (2) for the water thermolysis). (2) (2 AlN + 3 H2O) + k * (H2O = H2 + O.5 O2) + (Al2O3 + 2 NH3), T > (k * 242 – 274) * 1000) / (k * 54 – 181). If k = 0.5, so T > 720 C. and OPEX cost of the hydrogen product practically is equal to a cost of energy consumed, or being including minus a cost of high temperature heat can be converted in electricity for sale from reaction (1). In a first case it is 121kJ/mol = USD121 * 1.1 = USD133/ton H2. In a second case it would be a big net profit. References. 2021 Annual Meeting.

Submitted on Aprill 07, 2026 to AIChE-2026 annual conference.

Zero-carbon hydrogen production by thermo-chemical water splitting. Abstract. Synergy of (1) New kind of catalysts. It is a reversible circular reaction (catalyst in wide sense), that is added to a target reaction to form a joint process. (2) Wind and solar energy can be in order of magnitude cheapened. For example, the water thermolysis at breakthrough lower temperature is estimated just below. (1) Catalyst is 0.5 * N2 + 1.5 * H2 = NH3, is joined with 0.365 mol of the water splitting, it gives a heat in electricity as a by-product and 0.365 mol of H2 at T > 770 Celsius vs. conventional 2500 C. Because all reagents are circular and so practically free, the hydrogen OPEX cost is a cost of energy consumed, so a heat of (55 + 0.365 * 248) kJ = 139 kJ /0.365 = 400 kJ/mol minus a cost of the sold electricity, and with a Capex of USD 67/ 0.73 = 90/ton H2, it is in sum about USD 170 /ton H2. (2) Catalyst: CO2 + H2 = HCOOH - formic acid. Joint target reaction: HCOOH + 0.4 * (H2O = H2 +...
