Promising technology of H2, NH3, oil and gas production February 11, 2026 Abstract. (1) H2O + NH3 = 0.5 N2 + 2.5 H2 + 0.5 O2 + 288 kJ. dS = 153 J/mol*K. (2) 2.5 H2 + 0.83 N2 = 1.67 NH3 - (46 * 1.67 = 77 kJ) can be sold as a by-product - electricity by 0.33 - efficiency and USD 0.03/kWh, so (3) If Q is a cost Opex, Q(1.67 - 1 = 0.66 NH3) = 288 * 4 / 3.6 - 77 * 2.5 = USD 124 = 0.66 * 17 ton NH3 = 11.3 ton NH3, so Q(NH3) = USD 124 /11.3 ton = USD 11/ton NH3. Q(2.5 H2) = Q(NH3) * 17, so Q(H) = 11 * 17 / 5 = USD 37 / ton H2. Notes: (1) Renewable energy can be as cheap as about USD 0.004 /kWh. [1], [2], [3], [4], [5] etc. (2) 2.5 H2 / 3 = 1.67 mol NH3, here nitrogen can be practically free, being remainder of the air after its oxigen being deleted by negligible share of a fuel: hydrogen or ammonia. (3) Reaction (1) is converting 1 mol of NH3 in 1.67 mol NH3, can be grown exponentially. (4) CO2 + 4 H2 = CH4 + 2H2O - 254 kJ, so Q(CH4) = (220 + 4 * 37 - 254 kJ) / 16 = USD 23 / ton CH4 = USD 16 ...

Comic strip, or abstract of abstract, in short "comics" of multi-page or mega-page book, scientific work, etc. of printed or internet form, can allow quick reading and search them. Mostly, it is enough to read "magic first five lines of them" to understand what can wait him from the rest ones, and he can scroll pages only. The comics allows to address the reader to key information only to read it more attentively.

New conception of catalysts. The water termolysis at down to 365 Centigrade as an example. David Judbarovski, systems engineering, principle inventor, CV [6], judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. (1) CO2 + H2 = CO2H2 - formic acid. Such reaction can be considered as the catalyst being circular and drastically lowering a temperature for the water thermolysis . See: (2) (CO2H2) + 0.5 (H20 = H2 + 0.5 O2) + (CO2 + H2) at down to 365 C and pressure. Really. Energy for those can be renewable and as cheap as less USD 0.01 /kWh down to 0.4 cents or less. [1], [2], [3], [4], [5] and so on. Reaction (1) is classical. dH = - 32 kJ, while dS = - 214 J/mol * K. Reaction (2) goes at dH = 32 + 0.5 * 242 = 153 kJ. dS = 214 + 0.5 * (131 + 102 - 180) = 240. dG = 153,000 - 240 * T 365 C and pressure.. Because all reagents here are circular and practically free, a cost of the hydrogen is equal the cost of energy consumed only, so Q(H) = (153 kJ - 32 kJ) * 4/3.6 = USD 133/t...

New kind of catalysts. Circular formic acid as example. December 24, 2025 New kind of catalysts are an exothermic reversible reaction being combined with another reaction in joint chemical process, to make it happen at designed conditions and to restore the said reversible reaction's reactants. David Judbarovski, systems engineering, principle inventor, retired, judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. (1) CO2 + H2 = CO2H2 - formic acid, it is the said catalyst, beinmg the said exothermic reversible reaction. (2) (CO2H2) + 0.5 H20 = 0.5 H2 + 0.25 O2 + (CO2 + H2). It is the said joint chemical process to split the water at quite mild conditions and served to produce cheap hydrogen. Really. Energy for those can be renewable and as cheap as less USD 0.01 /kWh down to 0.4 cents or less. [1], [2], [3], [4], [5] and so on. Reaction (1) is classical. dH = - 32 kJ, while dS = - 214 J/mol * K. Reaction (2) goes at dH = 32 + 0.5 * 242 = 153 kJ. dS = 214 + 0.5 * (131 + 102 -...

Water thermolysis at breakthrough lower temperature with a help of CatERR. January 12, 2026 Note: CatERR is a new kind of catalysts are an exothermic reversible reaction being combined with another reaction in joint chemical process, to make it happen at designed conditions and to restore the said reversible reaction's reactants. David Judbarovski, systems engineering, principle inventor, retired, judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. Here CatERR can be 0.5 N2 + 1.5 H2 = NH3, dH = - 46 kJ, dS = - 103 J / mol * K, and the water thermolysis is (NH3) + 0.25 (H2O = H2 + 0.5 O2) + (0.5 N2 + 1.5 H2), dH = 46 + 0.25 * 242 = 106, dS = 103 + 0.25 * (131 +102 - 180) = 116, and dG = 106,000 - 116 * T 640 C. Moreover, because all reagents here are circular and practically free, a cost of the hydrogen is equal the cost of energy consumed, while the heat of the CatERR can be converted effectively in electricity and sold, the H2 is 106 kJ * 1.1 - 46 * 2.5 = negligible + Cap...

January 05, 2026 Novel possibility to power EV-s indirectly from remote solar and wind plants. [1], [2]. David Judbarovski, systems engineering, principle inventor, judbarovski@gmail.com judbarovski.blogspot.com Abstract. It is possible for solar PV-panel to be equipped above the roof of electric vehicles, partly to compensate electricity consumption by their batteries. For example, if sun light is 1500 kWh/m2 annualy on the said PV-panel with its energy efficiency 20% and area being 1.5 m2, it can add maximally 450 kWh to the said battery annualy. so negligible for the batteries daily, but very sufficient economy for regional and global electric grids. Really, for the Los Angeles city only, [3], [4], the system offered here can save 450 kWh * 7.0 million cars registered now * 25% EV in total cars in 2035 yr., so about 1.0 milliards kWh, so to substitute about 0.5 Gigawatt power of new built thermal and nuclear power plants (TPP or NPP ) by clean and cheap renewable energy.
