Tremendous economics and ecology by offered H2 and CH4 production

Tremendous economics and ecology by offered H2 and CH4 production. Author: David Judbarovski, systems engineering, principle inventor, retired; 1939dmj@gmail.com; judbarovski.blogspot.com. davidjud.blogspot.com, Reference: [1] "Mass production of CO2 at attractive cost from the air" - can be used for CH4 synthesis judbarovski.blogspot.comm/2020/01 posted on 11 Jan 2020 [2] "Breakthrough cheap Re energy" - solar and wind cost; judbarovski.blogspot.com/2024/06 davidjud.blogspot.com/2024/06 the both are on 21 Jun 2024 Resume: H2 = 9.2 UScent / kg, CH4 = USD25 / 1000m3, CH2 = USD 4 / bbl the all by OPEX. CO2 / H2 = 44 / (2*3) = (7.3 ton CO2) / 1ton H2 + 4.7 ton CO / 1 ton H2 - valuable by-product; CO2 / CH4 = (4/3 - 1) * 44/16 = 0.91 ton CO2 /1 ton CH4 C/CH4 = (2 * 12) / 16 = 24 / 16 = 1.5ton C / 1ton CH4 150 * 10^9 m3 CH4 (for Germany) * USD25/1000m3 OPEX * 2 = USD 8 * 10^9 * 5 years/ USD 470 * 10^9 – federal budget / USD 4 * 10^12 GDP Abstract: 2C + H2O = CH2 + CO -131 kJ, at T > 460 grad.C 2C + 3H2O = CH2 + 2H2O + CO = 3H2 + CO2 + CO - 355 kJ. H2 = (2 *12* USD 120 /ton C– 44 * USD 30 / ton CO2– 28 * USD 50/ton CO) = USD 160 / 6 = USD 27/ ton H2; ((355 * 10^6 kJ * USD/kwh 0.004) / (3600 sec.*(3H2= 6)) = USD 65/ton H2, And totally 27 + 65 = USD 92 /ton H2 = UScent 9.2/ kg. CO2 + 4 H2 = CH2 +2H20 + 254 kj. (1144 kwh/ton (CO2) * 44 * USD 0.004 /kwh + 8 * USD 92/ton H2) /16 = USD 45/ ton CH4. ((254 * 10^6 kj / (3600 sec. * 16)) * USD 0.03 per kwh * 0.3 energy efficiency heat in electricity = USD 10.0 for selling. So totally CH4 = 45 – 10 = USD 35/ton CH4 = USD 25 /1000 m3. CH4 – H2 = CH2 = (16 * 35 – 2 * 92) /14 = USD 26.8 /ton CH2 = USD 4 /bbl

Progressive city-car realization and powering-Updated,#1

Progressive city-car realization and powering-Updated, #1 Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ Archive since 2017 yr: http://judbarovski.blogspot.be Archive since 2006 yr.: http://judbarovski.livejournal.com [3791]-3/11/2017,   My three levels’ conception of progressive transportation was disclosed in http://www.judbarovski.blogspot.co.il/2017/05/progressive-transportation-manifesto.html  (Progressive transportation manifesto, May 02. 2017). Its first level is a city-car.   Special designed city-car is a car moved electrically and equipped by very small battery as a city-grid element, and it isn’t big news now. Such cars are to be much cheaper and simpler than conventional cars and save a lot of energy. But I can suppose strictly to reject all sorts of powering them from underground, because it is energy ineffective and creates additional

Progressive Transportation Manifesto

Progressive Transportation Manifesto. Author: David Judbarovski, systems engineering, retired engineer, Israel judbarovski@gmail.com , Linkedin: David Judbarovski  http://judbarovski.livejournal.com ,  http://judbarovski.blogspot.co.il   It can be three levels global transportation system. (1) Urban traffic is provided by specially designed cars only and being electric pilotless cars fed from electric grid, with a tiny battery needed for emergency occasions only and offered as a new market products being a city taxi analogously to the UBER taxi optimized by time of delivery, number of passengers and cargo load. It’s ecologically friendly transport can save a lot of money and time for its users. It will avoid a human factor and traffic accidents.    (2) Personal cars must be avoided from cities’ roads and collected on the personal cars stations outside the cities and serving for suburb’s or rural routes up to about 700 km range. I can offer a special cars design fo

Fresh look, Japan offshore

Central Research Institute of Electric Power Industry Japan, https://criepi.denken.or.jp/cgi-bin/en/inquiry/inquiry_entry.cgi   Dear Secretary, I can suppose you to be no big professional in engineering, so please forward my very interdisciplinary message to your institute professionals of Energy Innovation Center and/or to your Planning Group having intellectual Property Sectors, as its high importance merits for Japan energy security and economics and independence.   1.5.2019 Abstract During last three years the Japan government’s energy authorities declared and then rejected different Strategic Energy Plans (“SEP”), each more stupid than the previous ones, but the all of them need some trillions USA dollars of budget and being depended from foreigners. Being uniquely educated & experienced engineer (see short CV in attachment), I can confirm that Japan can be energy independent after three years of works by about one milliard USA dollars of total budget.
