Green and cheap H2, CO, and hydrocarbons. Corrected on August 04, 2025. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract Simplified technology promises USD 161/ton H2, USD 11.5 /ton CO, and hydrocarbons of USD 6 /bbl. They are OPEX, and in order of magnitude cheapеr than prices of fossil fuel and can use now existing infrastructure. (a) CO2 [1] + H2 = CO + H20 - 3 kJ negligible. Here everywhere CO2 is circular and free. A cost of H2O is negligible. If Q served for a cost, Q(CO) * 28 = Q(H) * 2, so Q(CO) = Q(H) / 14. (b) [2] CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2 + 146 kJ. 146 kJ = 146 * 4/ 3.6 [3], [4] = USD 161.0 /Mmol. 1.5 * 2 * Q(H) - 161 = Q(CO) * 28 = 2 Q(H). So Q(H) = USD 161 / ton H2. and CO = Q(H)/14 = USD 11.5 /ton CO. QED ! CO2 + 3 H2 = CH2 (hydrocarbons) + 2 H2O - 240 kJ. 240,000 * 0.3 (efficiency heat in electricity) * 0.03 (tariff) / 3.6 = USD 600 /Mmol So 14 * Q(CH2) = 5 * ...

CO2 reduction by H2 into hydrocarbon (CH2), symplified. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com Abstract. A chain of those four reactions allows at started USD cost 400 /ton H2 to turn it in 90 OPEX at the end CO practically free. Heat of exothermic reactions can be converted in electricity and sold, so drastically deminish a cost of H2, CO, and CH2 down to about 3.5 cent/liter. (1) CO2 + H2 = CO + H2O. (2) CO + 1.5 H2O = CO2 + 1.5 H2 + O.25 O2 (3) CO2 + 1.5 H2 + O.25 O2 = CO + 1.5 H2O. (4) CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2. Here, CO2 is free being a circular reagent. (5) CO + 2 H2 = CH2 + H2O, or CO2 + 3 H2 = CH2 + 2 H20. Reference. Really. [1] CO2 mass production from the air very cheaply, judbarovski.blogspot.com/2025/01, posted on 12 January, 2025.

CO2 reduction by H2 into CH2 practically free and distribute Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com Abstract. . - CO2 + 3 H2 = CH2 + 2 H2O - 239 kJ. Gibbs criteria is negative in wide spectra of temperatures Here CO2 can be directly captured from the air [1] by less than 1144 kWh /ton CO2. H2 is down to USD 200 /ton H2 can be produced by three steps from the CO2 and the water. [2]. CO2 + 3 H2 = CH2 + 2 H2O - 239 kJ. (239 * 10^6 / 3600 sec.) kWh * 0.3 efficincy * 0.03 tariff = USD 600. CH2 = (1144 * 0.004 + 3 * 2 * 200 - 600) / 14 + 20% = USD 44 / ton CH2 = USD 6.3 /bbl = 4 cent / liter. . Energy for such technology was developed down to 0.4 cents /kWh [3], while its byproducted electricity can be sold to decrease OPEX. And totally, CH2 can be USD 6.3 /bbl and produced carbon negative and distribute. Really. [1] CO2 mass production from the air very cheaply, judbarovski.blogspot.com/2...

Grid-scale Energy Storage by breakthrough cheap artificial fuels. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com Abstract. CO2 + 2 NH3 = CH2 (abbreviation of hydrocarbons) + N2 + 2 H20. CH2 is incredible awesome USD 8.0 / bbl OPEX = USD 57 /ton CH2 = 8.0 cent / liter CH2 !!! Here NH3 is USD 28 /ton synthetized from N2 created by burning a small amount NH3 in the air, while H2 is USD 200 /ton [1], the both of them are zero carbon. Such cheapness is reached by sold electricity being byproduct. References.
