Background. H2/NH3/CH2/CH4/CO/CO2 simplified production

Background. Simplified H2/NH3/CH2/CH4/CO/CO2 production, is zero-carbon, circular and practically free. August 26, 2025 Simplified production of zero-carbon, circular and practicaly free H2, NH3, CH2, CH4, CO, and CO2. David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Background. Integratioon of huge share of Re energy directly in national grids was and is unsolvable. It needs intermediate arrtificial fuels, desirable to be green, cheap, and circular. It needs primary energy cheaper USD 0.01/kWh, cheap raw materials and tools to be competitive. The device was developed by Aircela Inc.is looked very promising, but uses expencive water electrolisis for H2 production, and problematic potassium hydroxide to extract CO2 from the air. Their chemistry is (1) CO2 + 2 H2 = CH3OH + O.5 O2. (2) CH3OH - CH2 + H2O. Nevertheless, even if they apply our approach and our improvements forming Simplified production of H2/NH3/CO2/CH4/CO/CO2, is zero-carbon, circular and practically free, their way needs upto twice more primary energy per Mtoe (Mton of oil equivalent). Description. (1) CO2 + H2 = CO + H2O - 3 kJ. (2) CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2 + 143 kJ of such thermochemistry - 3 kJ = 140 = USD 154/Mmol heat. [1] and totally Q(H) = USD 154 / ton H2. (3) 0.5 N2 + 1.5 H2 = NH3 - 46 kJ = 46,000 * 0.3 (efficiency heat in electricity) * 0.03 (tariffs) / 3.6 = USD 115 / Mmol. Here N2 is practically free, if a share of the NH3 burns oxygen out of the air formed totally 7 mol N2 for 7 mol additional NH3 production. Such NH3 is USD 20 / ton NH3, OPEX, and totaly with Capex is not more than about USD 50 or so. (4) CO2 + 3 H2 = CH2 + 2 H2O + 229 kJ = USD 573 /Mmol electricity as a by-product, and Q(CH2) = (5 * 44 + 6 * 154 - 573) / 14 = 570 / 14 = USD 40 / ton CH2 = USD 5.7 / bbl. (5) CO2 + 4 H2 = CH4 + 2 H2O. CH4 = USD 35 /1000 m3. References. Comments
