UMSICHT Fraunhofer, 15/11/2025

UMSICHT Fraunhofer institute. Prof. Dr.-Ing. Christian Doetsch, Head of the institute. Dear Friends. My offer to you is actual, and relevant, being very interdisciplinary. Even if unsolicited, sorry me, but it merits of your attention. It is incredibly cheap, zero-carbon, hazard-free, compact, circular, distributed, and domestical supply and demand everywhere and of any designed schedule. Abstract. Estimations: Hydrogen by USD 133 /t,on, NH3 by USD 17 /ton, CH2 (oil) by USD 4.6 /bbl, CH4 by USD 18 /1000 m3. All those by Opex. See a short disclosure just bellow. judbarovski.blogspot.com/2025/10, posted on Oct. 30. Can I see allies in you, and hope for feedback. And I am ready to pay money received now by me from Germany as a victim. Short disclosure. (1) Hydrogen. (a) CO2 + H2 = CO + H2O + 41 kJ, reversible reaction. (b) (CO + H2O) + 0.5 * H2O = 0.5 * (H2 + 0.5 * O2) + (CO2 + H2) = CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2 + 80 kJ of such thermochemistry + 41 kJ of reaction (a) = 121 kJ = USD 133 /Mmol heat. dG = 80 kJ + 6 * T . Being circular, CO2 and CO are practically free, and totally Q(H) = USD 133 / ton H2. (2) Ammonium. 0.5 N2 + 1.5 H2 = NH3 - 46 kJ exothermic reaction with its heat into electricity. 46 Mmol heat * (0.3 effectiveness of heat in electricity) * (0.03 tariffs) / 3,600 = USD 115. Here N2 is practically free, if each mol of the NH3 burns oxygen out of the air forming 3.5 mol N2 for 7 mol additional NH3 production. Such NH3 is (2 * 1.5 * 133 - 115) / 17 = USD 17 / ton NH3, OPEX, and totally with Capex is not more than about USD 50 /ton NH3 vs. present world markets prices of USD 650-850. (3) CH2 (Oil). CO2 + 3 H2O = CH2 + 2 H2O, exothermic reaction with the heat in electricity as a by-product. (4) CH4 (methane). CO2 + 4 H2 = CH4 + 2 H2O, exothermic reaction with its heat into electricity as a by-product. References.

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 * ...
