Zero-carbon and practically free H2, NH3, oil and gas. Edited

February 26, 2026. Simplified production of zero-carbon, circular and practically free H2, NH3, CH2, CH4, CO, and CO2. August 24. 2025. David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. (1) CO2 + H2 = CO + H2O - 44 kJ heat, can be converted in electricity as a by-product. (2) CO + 1.4 H2O = CO2 + 1.4 H2 + 0.5 O2 + 56 kJ of such thermochemisty, T > 330 C. CO and CO2 are here practically free, because they being circular, so Q(H) = 56 kJ * 1.1 /0.8 = USD 77/ton H2, [1]. (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 of sold electricity as a by-product. Here N2 is practically free, if a mol of NH3 burns oxygen out of the air forming totally 7 mol N2 for 7 mol NH3 production. Such NH3 is 77 * 3 / 17 = USD 14 / ton NH3, OPEX, and totaly with Capex no more than about USD 50 or so, and income by sold electricity as by_product. (4) CO2 + 3 * H2 = CH2 + 2 H2O - 224 kJ heat in electricity for sale. Totally it is USD 32 / ton CH2 = USD 4.5 / bbl, and income by sold electricity (5) CO2 + 4 H2 = CH4 + 2 H2O. CH4 = USD 23/1000 m3. References. [1] Breakthrough cheap Re energy, judbarovki.blogspot.com/2024/06, posted on June 21.2024.

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 ...

Extremely compact and hazard free way, opening a door for realistic hydrogen economics.

Extremely compact and hazard free way to store, and delivery, and usage of NH3, opening a door for realistic hydrogen economics. [1],[1a]. David Judbarovski, systems engineering, principle inventor, 85, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. Ammonia being greatly soluble in the water, it can and must be produced well scalably and distributely and remotely by my supercheap renewable energy [2], [2a], and stored and trasported at very mild conditions of temperature, pressure, compactness, safety, and cost up to three order of magnetude better than its conventional alternatives. The ammonia or its hydrogen can be turn in electricity, including direct mobile applications. NH3 storage and trasportation as an example. At 10 C and less 1 atm, such solution can be 900 g NH3 / kg water, or 1000 liters NH3 /liter H20 solution either in storage tank or in a tube for transportation. 1t is extremaly important for safety in war time and against terrorist attac...

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 cheapŠµr 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 * ...
