A roadmap to cheap and green hydrocarbons fuel. Edited.

(1) Cheap renewable energy. To be competitive, artificial fuel needs for its synthesis from CO2 of the air and H2 by the water splitting, energy for it must be cheaper than USD 0.01/kWh or so. A cost of primary energy of Solar and Wind in the order of magnitude can be cheapened by reducing their frontal dimensions down to about 1.0 m2 unit, so such units are thinner proportionally and their cost negligible vs. a cost of electric generators being a lion's share per kilowatt, and cheaper than USD 0.005/kWh. For example, see 2021 Annual Meeting. (397e) Cheap Energy is Key to Competitive Artificial Fuels. www.aiche.org/conferences-events. (2) Breakthrough cheap and green and inexhaustible Hydrogen production by low temperature water thermolysis at about 300 C vs. 2500 C conventional and sufficiently lower than auto-ignition at 450-500 C, instead of very expensive electrochemistry. I can offer 4 different technologies of it by USD 120-170 /ton H2. See: judbarovski.blogspot.com/2026/07,...

Cheapening of oil and gas. Upgrade of 26.09.2026

Cheapening of oil and gas. Upgrade of 26.09.2026 David Judbarovski, systems engineering, 1939dmj@gmail.com, +972-54-6000514. judbarovski.blogspot.com Abstract. (1) Solar and Wind energy can be cheapened down to $ 0.01/kWh and even much less. [1]. (2) Roadmap to cheap and green hydrocarbon fuels. [1]. In these cases, classical hydrogenation of CO2 allows oil by $41-$52 /ton ($6-$7 /bbl) and gas by $41-$56 /ton (about $35/1000 m3) OPEX at quite mild conditions. References.

Drastically cheapened Ethylene.

David Judbarovski, systems engineering, principle inventor. Judbarovski.blogspot.com, judbarovski@gmail.com. Notes. (1) Solar and Wind energy can be cheapened down to $ 0.01/kWh and even much less. [1]. (2) Roadmap to cheap and green hydrocarbon fuels. [1]. (3) Cheapening of oil and gas production down to $ 6-7.4/bbl [2]. Abstract. Ethylene OPEX cost can be $70/ton vs more than $1000/ton now. How it works: It is a two-steps chemical process. (1) CH2(abbreviation of hydrocarbons) + H2O = CO + 2H2. dH = 167, dS = 245. (2) 2CO + 4H2 = C2H4 + 2H2O - exothermic reacton. Here 4H2 is circular, and so being practically free. Q (CO) = (14 * 52 + 167 * 1.1)/28 = $33.O/ton CO. Q (C2H4) = 2*28*33/28 = $66/ton C2H4. In the another case, 2CH4 = C2H4 + 2H2, dH = 2 * 75 - 53 = 97 kJ, dS = 219 + 262 - 2 * 186 = 129 J. Q (2C2H4) = (2 * 16 * 55 + 97 * 1.1) / 28 = $67 / ton C2H4. 2H2 is a by-product, can be used here in 0.5 CH4, circular + 0.5 CO2, so totally will be $47 /ton C2H4. Reference...

Supercheap and clean hydrocarbons' production

David Judbarovski, systems engineering, principle inventor. Judbarovski.blogspot.com, judbarovski@gmail.com. Note. Solar and Wind energy can be cheapened down to USD 0.01/kWh and even less. [1] Abstract. (1) 2CH2 (alkane) + 2H2O = CH4 + CO2 + 2H2 , dH = 72 kJ, dS = 220 J/mol*K (2) CO2 + (3 – 1) H2 = CH2 + 2H2O. exothermic. OPEX cost of alkane is USD 64 /ton CH2, or USD 9.0 /bbl. (3) = (1). OPEX cost of CH4 = (2 * 14 * 64 + 72 * 1.1) /16 = $ 120/ton CH4 = $ 84/1000 m3.

Израильтяне выбирают пробки: развитие инфраструктуры не смогло пересадить страну на общественный транспорт 2 сентября 2026, 15:14 Экономика За последнее десятилетие транспортная карта Израиля существенно изменилась: открылись новые железнодорожные линии, запущены линии легкорельсового транспорта, а автобусные сети расширили свои маршруты. Однако ожидания государства столкнулись с прямо противоположной реальностью. Согласно свежим данным опроса Центрального статистического бюро за 2025 год, жители страны предпочитают ежедневно простаивать в заторах на личных автомобилях, а популярность общественного транспорта продолжает падать.

Uzbekistan. The Renewable water supply. September 2, 2026

It is a device, can produce fresh water, abundant and inexhaustible, by 26 cents /m3-payback 1 year + 0.2 kW electricity + 0.15 kWh recycling. It is a small, compact and mobile device. Who is me: See cv-2023, davidjud.blogspot.com/2023/04, posted on April 27, 2023. What I want: To join a small group for possible patenting as a novel method/technology and introduce it by startups. How it works: It pulls natural air and transforms its humidity in liquid water by chain: fan-turbulator-desiccant-its recycling-condenser, when heat being its by-product used for recycling. David Judbarovski, systems engineering, principle inventor, judbarovski.blogspot.com, judbarovski@gmail.com. P.S. Shortly. If a work season from March to October is about 5900 hr., absolute humidity averaged is 10 g/m3 at 15 nm3/s the fan, so it is 3200 m3 H2O production in a year. If a cycle is one hour, CaCl2 desiccant of 1 year lifetime, 250 $/ton = 0.26 cent / m3 H2O. The fan consumes 0.2 kW electric...
