CO2 reduction by H2 into hydrocarbons (CH2), simplified.

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

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.

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.

Unusual chemistry promises green and incredibly cheap CO and H2 and hydrocarbons fuels.

Unusual chemistry [1] promises green and incredibly cheap CO and H2 and hydrocarbons fuels. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovskli@gmail.com, judbarovski.blogspot.com . Abstract. (A) CO2 + 1.5 H2 + O.25 O2 = CO + 1.5 H20 + 146 kJ. 146,000 * 0.3 * 0.03 / 3.6 = USD 365 electricity for sale. (B) CO + 1.5 H2O = C02 + 1.5 H2 + 0.25 O2 - 146 kJ. - 146 * 4 / 3.6 = - USD 160. Step 1-st. CO2 is free, circular. CO = USD 37 and H2 = USD 410, the both are ordinary. CO = (1.5 * 2 * 410 - 365) / 28 = USD 31 /ton CO H2 = (28 * 31 + 160) / 3 = USD 342 /ton H2. Step 2-nd. CO = (3 * 342 - 365) / 28 = USD 24 /ton CO. H2 = (28 * 24 + 160)/ 3 = USD 277 /ton H2. Step 3-rd. CO = (3 * 277 - 365) / 28 = USD 17 /ton CO. H2 = (28 * 17 + 160) / 3 = USD 212 / ton H2. CO + 2 H2 = CH2 + H2O, CH2 = (17 * 28 + 4 * 212 - 590) = USD 734 = USD 7.3/ bbl. Reference. [1] Catalytic reduction of CO2 by H2, merthanol and hydrocarbons: chellenges and opport...

Three steps breakthrough cheapening H2, and CO and hydrocarbons (CH2) - Upgraded

Three steps breakthrough cheapening H2, and CO and hydrocarbons (CH2) - Upgraded Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. Non usual simple way allows from air and water to synthesize hydrocarbons fuels (CH2 abbreviated) being green and cheap and well scalable and can be distributed as in production as in applications. (A) CO2 + 0.25 O2 + 1.5 H2 = CO + 1.5 H2O + 146 kJ, 146,000 * 0.3 * 0.O3 / 3.6 = USD 365 electricity for sale. (B) CO + 1.5 H2O = C02 + 1.5 H2 + O.25 O2 - 146 kJ, 146 * 4 / 3.6 = USD 160 [1]. CO2 is free, being used in cycle. If H2 Opex being ordinary USD 400 / ton H2 at start way [2], so the 1-st round is CO = (1.5 * 2 * 400 - 365) / 28 = USD 30 /ton CO. H2 = (30 * 28 + 160)/(1.5 * 2) = USD 333/ ton H2. The 2 nd raund is CO = (1.5 * 2 * 333 - 365) / 28 = USD 23 / ton CO, H2 = (23 * 28 + 160) / 3 = USD 268 / ton H2. Round 3 is CO = (3 * 268 - 365) / 28 = USD...

Three steps breakthrough cheapening H2, and CO and hydrocarbons (CH2)

Three steps breakthrough cheapening H2 and CO and hydrocarbons (CH2 abbreviated). Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski@gmail.com, judbarovski.blogspot.com The first step from CO = USD 37 /ton, and H2 = USD 410 /ton. (1a) CO + 2 H2O = CO2 + 2H2 + 0.5 O2 - 289 kJ. 289 * 4 /3.6 = USD 320 [1]. H2 = (37 * 28 + 320) / 4 = USD 339 /ton H2. and CO2 is free. (1b) CO2 + H2 = CO + H2O + 3 kJ negligible. CO = 2 * 339 / 28 = USD 24 / ton CO. The second step. (2a) CO + 2 H2O = CO2 + 2 H2 + 0.5 O2 - USD 320. H2 = (24 * 28 + 320) / 4 = USD 248 / ton H2. (2b) CO2 + H2 = CO + H20 - 3 kJ. CO = 2 * 248 / 28 = USD 18 / ton CO. The third step. (3a) H2 = (18 * 28 + 320) / 4 = USD 206 / ton H2. (3b) CO = 2 * 206 / 28 = USD 15 / ton CO. So CO + 2 H2 = CH2 + H2O, and CH2 = (15 * 28 + 4 * 206) / 14 = 1240 / 14 = USD 88 / ton CH2 = USD 12.4 /bbl
