Zero-carbon and cheap hydrogen production , changing a game.
September 19, 2025 Breakthrough cheap and zero-carbon hydrogen production can change a game in chemistry and energetics. David judbarovski, systems engineering, principle inventor, retired. judbarovski.blogspot.com, judbarovski@gmail.com. (a) CO2 [1] + H2 = CO + H20 + 41 kJ. Such reactiuin is well known (1780 yr., rewersible WGSR - Water-gas shift reaction) and circular here, so it is for free. (b) The novelty is thermochemistry being (CO + H20) + 0.5 H2O = O.5 * (H2 + 0.5 O2) + (CO2 + H2) + (- 41 + 242/2) = 80 kJ - USD 88 / ton H2. [2], [3]. dG = 80 kJ + 65 * T, so it neens catalysts, can be the iron, and additional heating. References.
