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 1300 liters NH3 /liter H20 either in storage tank or in a tube for transportation. It is reachebly by conventional pressing of about 1000 atm. QED !!! 1t is extremaly ...

Incredibly cheap and zero-carbon NH3 production.

Incredibly cheap and zero-carbon NH3. It is important step towards the implementation of H2 energy from a dream to reality by following strategy. (1) distributed renewable energy generation, (2) well scalable NH3 production by the said RE energy on saveful places eiher not so far away of dense settlement, or for the NH3 storage tanks, (3) conversion of NH3 in electricity, of any shedule for powering. David Judbarovski,systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com Short disclosure. Here CO2 and CO are circular and practicaly free. (1) CO2 + H2 = CO + H2O - 3 kJ. (2) CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2 + 146 kJ of such thermochemistry - 3 kJ = 143 = USD 157/Mmol heat. [1], and totally Q(H) = USD 157 / ton H2. 0.5 N2 + 1.5 H2 = NH3 - 46 kJ. 46 Mmol heat * (0.3 effectiveness heat in electricity) * (0.03 tariffs) / 3,600 = USD 115.[1]. Here N2 is practically free, if each mol of the NH3 burns oxygen out of the air forming 3.5 mol...

Breakthrough cheap and zero-carbon hydrogen production

Breakthrough cheap and zero-carbon hydrogen production can change a game in chemestry and energy. David judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. (a) CO2 [1] + H2 = CO + H20 - 3 kJ. Being circular, CO2 is free here. If Q served for a cost, Q(CO) * 28 = Q(H) * 2, so Q(CO) = Q(H) / 14. (b) CO + 1.5 H2O = CO2 + 1.5 H2 + 0.25 O2 + 146 kJ. 146 kJ - 3 = 143 * 4/ 3.6 [2] = USD 157.0 /Mmol. Really, 1.5 * 2 * Q(H) = Q(CO) * 28 + USD 157 = 2 * Q(H) + USD 157, so Q(H) = USD 157 /ton H2 References.

Israel and Ukraine at first

I am David Judbarovski, ISRAEL, systems engineering, principle inventor, the both are very interdisciplinary, more than 60 years of productive experience. Synergy of two fundamental engineering principles would allow technology of practically free. and zero-carbon, and circular production, being well scalable H2, NH3, CH2, CH4, CO, CO2. See judbarovski.blogspot.com/2025/08, posted on August 27, 2025. It would be great at first to be developed and introduced in Israel and Ukraine in their mortal struggle for existence in war time. And I will be glad to help them at first 10,000 EURO and expearence, and a real way to energy independency from impudent exporters of oil and gas in really short time and to break their financing of the war and terror against Israel and Ukraine. Sincerely, David Judbarovski, judbarovski@gmail.com, 1939dmj@gmail.com
Dear professor Boris Rybtchinski. Date: 9/9/2025. Adoni professor ! Can I suppose, you can speak Russian quite influently and had studied Germanit in University.
