Breakthrough cheap and green hydrogen can change a game.

Breakthrough cheap and green hydrogen production can change a game in energy and chemistry and so on. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. USD 11.5 /ton CO, H2 is down to USD 150 /ton, and hydrocarbons of USD 6 / bbl. They are OPEX, and in order of magnitude cheapеr than prices of fossil fuels and can exploit existing infrostructure. (a) CO2 [1] + H2 = CO + H20 - 3 kJ negligible. CO2, CO and H2 are circular. 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.. Really, 1.5 * 2 * Q(H) = Q(CO) * 28 + USD 161 = 2 * Q(H) + USD 161, so Q(H) = USD 161 /ton H2. Q(CO) * 28 = Q(H) * 2, so Q(CO) = Q(H)/14 = USD 11.5. QED ! CO2 + 3 H2 = CH2 + 2 H2O - 239 kJ. 239,000 * 0.3(efficiency heat in electricity) * 0.03(tariff) /3.6 = USD 600.0. So Q(CH2) = (44 * Q(CO2) + 3 * 2 * Q(H) - USD 600) / 14 = (44 * 5 + 6 * 161 - 600) /14 = 586 / 14 = USD 42 / ton CH2 = USD 5.85 / bbl. Instead of attractive, but problematic reaction (b), it can be considered spontaneous reaction CO + 1.2 H20 = CO2 + 1.2 H2 + 0.1 O2, to produce H2 of USD 150 /ton, and further hydrocarbon fuels are USD 5.6 / bbl.

Progressive city-car realization and powering-Updated,#1

Progressive city-car realization and powering-Updated, #1 Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ Archive since 2017 yr: http://judbarovski.blogspot.be Archive since 2006 yr.: http://judbarovski.livejournal.com [3791]-3/11/2017,   My three levels’ conception of progressive transportation was disclosed in http://www.judbarovski.blogspot.co.il/2017/05/progressive-transportation-manifesto.html  (Progressive transportation manifesto, May 02. 2017). Its first level is a city-car.   Special designed city-car is a car moved electrically and equipped by very small battery as a city-grid element, and it isn’t big news now. Such cars are to be much cheaper and simpler than conventional cars and save a lot of energy. But I can suppose strictly to reject all sorts of powering them from underground, because it is energy ineffective and ...

Green and cheap H2, CO, and hydrocarbons. July 14. 2025

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 * ...

Fuels, simply and cheaply

 Fuels, simply and cheaply. Author: David Judbarovski, systems engineering, principle inventor, retired. See my professional CV  shortly in Linkedin.com. judbarovski.blogspot.com, judbarovski@gmail.com .  Preamble  My variant is based on extremally cheap solar and/or wind energy as a result of many   years of my research and development. The said breakthrough cheap fuels can be produced domestically, distributed, and cheaply, and it allows to integrate huge amount of  renewable energy in national grids, being now a sore and unsolvable problem.      Roadmap manifesto from present energy fiasco via realistic half-greens to clean energy. And so on, and so on. Really. For classical Fischer-Tropsch process: (1) C + H2O = CO + H2 - 173 KJ, (2) 2H2 + CO = CH2 + H2O + 250 KJ (3) surplus CO -sold, by 50 * 28 = USD 1400, CH2 = 120 * 12 = USD 1440 + 173 * 4/ 3.6 = USD 200, And 250,000 * 0.3 (efficiency heat in electricity) * 0.033 /3.6 = USD 700.
