Tremendously cheap and green ammonia can change a game - Upgraded. David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. Chain of improvements: (1) Re energy by UScents 0.4 /kWh, 5 years payback and breeding investments for acceleration. [1], [2].[3] (2) Reduction in size of the generators' units. Small size = "thin walls" drastically diminish ratio a cost of kWh. (3) N2 is practically free, "share of NH3 burns oxygen out of the air" vs. conventional cryogenic monster. [4]. (4) H2 can be down to USD 150 /ton. [1]. 0.5 N2 + 1.5 H2 = NH3 - 46 kJ, Haber-Bosch process. 46,000 * 0.3 (efficiency heat in electricity) * 0.03(tariffs) / 3.6 = USD 115/Mmol heat in electricity. Q(NH3) * 17 = Q(1.5 H2) = 3 * 150 - 115 = 335, so Q(NH3) = 335 / 17 = USD 20 /ton NH3 vs. now prices being USD 650 -850 /ton NH3. If + 250% for Capex, NH3 would be USD 50 / ton. Such cheap ammonia allows to synthetise...

Breakthrough cheap and green CH4 production and delivery, can be patented. You can join it. David Judbarovski, systems engineering, principle inventor, retired, judbarovski.blogspot.com, judbarovski@gmaii.com Abstract. CO2 + 4 H2 = CH4 + 2 H2O, Sabatier reaction. The reaction's heat can be transformed in electrsity can be sold and sufficiantly to cheapen the CH4. (a) CH4 = USD 34 / 1000 m3, at USD 150 /ton H2 See them in Breakthrough cheap and green hydrogen can change a game. judbarovski.blogspot.com/2025/08, posted on August 04, 2025; and CO2 mass production from the air very cheaply, judbarovski.blogspot.com/2025/01, posted on January 12, 2025; and CV-2023, davidjud.blogspot.com/2023/04, posted on April 27, 2023. I can recomMend big blimps (Airships with non-rigid walls) filled by CH4 being lighter than air simultaneously used as a propellant for the blimp to delive it closer to its consume.

Breakthrough cheap and green ammonia can change a game in hydrocarbon fuels production. Author: David Judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. Abstract5 0.5 N2 + 1.5 H2 = NH3 - 46 kJ, H2 can be about USD 150/ton [1], NH3 = (3 * 150 - 46,000 * 0.3(effectivenes of heat in electricity) * 0.03(tariffs) /3.6 ) = 420 / 17 = USD 25 /ton NH3 OPEX. N2 is practically free, because each mol of NH3 burnt in the air, gives N2 for additional 7 moles NH3 productions by simplest and cheapest way instead of conventional high-tech huge monster and expensive creagenic technology for the same purpose.

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...
