UMSICHT Fraunhofer, contact form, 13/11/2025 November 13, 2025 UMSICHT Fraunhofer institute. Prof. Dr.-Ing. Christian Doetsch, Head of the institute . Date: Nov. 13, 2025. 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. 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. It is an important step towards the implementation of H2 energy from a dream to reality by following strategy. (1) distributed renewable energy generation cheaper than USD 0.01 / kWh, (2) well scalable liquid or liquified fuels production distribute by the said RE energy and for storage, (3) such fuels can be used for powering of any designed schedule. They are especially important in war-time and against terrorists' attack (4)"Breeding investment", i.e. reinvesting of such excess profits allows to accelerate full implementation of the system. David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com. judbarovski@gmail.com Abstract. Estimations: Hydrogen by USD 133 /ton, 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. 2025. . 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. [1] Breakthrough cheap Re energy, judbarovski.blogspot.com/2024/06, posted on June 21. 2024.
