CO2 reduction by H2 into CH2

CO2 reduction by H2 into CH2 practially 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]. 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. 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. Reference. [1] CO2 mass production from the air very cheaply, judbarovski.blogs...

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 opportu...

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

New kind of transport as elite one, as instead of helicoptrrs. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. It is a transport of 10 cent/kg can be fixed in the sky motionless by VTOL [1], [2] or fly in any direction, upto 900 km/hr. 2000 km range, 100 kg of bipropellant (kerosene and pressed oxigen) per a ton proportionally. It can be fed by not big solar PV panel or by shuttle delivery or at refueling stations. References: [1] Take-off and landing Device, judbarovski.blogspot.com/2020/07, posted on 20.07.2020.

it can change a game for satellites

. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski@gmail.com, judbarovski.blogspot.com. It doesn't need a special start/land pods, but only permitted by ordinary air traffic safety regulation. Abstract. A key element of the possible invention is a VTOl and strategy can lift and land a satellite or/and materials relatively free if the VTOL design of my invention of 40 kW/ton, see Vertical take-off amd Landing Device - 20.07.2020, see judbarovski.blogspot.com/2020/07, posted on July 20, 2020. Satellite is served on low orbits, its PV direct solar illumination can be 10 hr.* 1.4 kW * 365 days a year = 5000 kWh/m2 of the PV receiver. Down to 10 km using ICE, expenses are negligible, then and lower than designed orbit it is CH2 + pressed oxigen for jet mover, and then accelerated. For example, if 100 ton satellite, to reach an orbit 300 km hight it consumes 2 hours and about 1.6 ton kerosene and 4.5 ton 300 atm. pressed oxigen by a tota...
