Renewables-2017

 Fuels, simply and cheaply. Author: David Judbarovski, systems engineering, principle inventor, retired. See my professional CV  shortly in Linkedin.com. judbarovski.blogspot.com, judbarovski@gmail.com .  Preamble  My variant is based on extremally cheap solar and/or wind energy as a result of many   years of my research and development. The said breakthrough cheap fuels can be produced domestically, distributed, and cheaply, and it allows to integrate huge amount of  renewable energy in national grids, being now a sore and unsolvable problem.      Roadmap manifesto from present energy fiasco via realistic half-greens to clean energy. And so on, and so on. Really. For classical Fischer-Tropsch process: (1) C + H2O = CO + H2 - 173 KJ, (2) 2H2 + CO = CH2 + H2O + 250 KJ (3) surplus CO -sold, by 50 * 28 = USD 1400, CH2 = 120 * 12 = USD 1440 + 173 * 4/ 3.6 = USD 200, And 250,000 * 0.3 (efficiency heat in electricity) * 0.033 /3.6 = USD 700.

 (1) 0.5 C + 0.5 CO2 = CO - 86 KJ   (2,) C  + H20 = CO + H2 -   173 KJ 3) CO +H2O = H2 + CO2 - 3 KJ - negligible. (4) CO + 2H2 = CH2 (hydrocarbons)  + H2O + 250 KJ. Materials' balance: for a mol CH2 are consumed 1.5 mol C, and exhausted 0.5 CO2 mol , and a mol CO is sold. If C being USD 120/ton, CO is sold by USD 50/ ton or much more expensive, and CO2 being 1144 kwh/ton by (USD 0.004 /kwh - see Preamble) = USD 4.5, Opex, so totally CH2 = (1.5 * 1 2 * 120 - 28 * 50 + 44 * 4.5) = 2160 - 1400 + 200 = 960. Energy balance: (86 + 173) * 4 / 3.6 - 250,000 * 0.3 efficiency heat in electricity * 0.033 local tariffs / 3.6 = 300 - 700 = - USD 400. And  CH2 = (960 - 400) = USD 460 / 14 = USD 33/ ton CH2 = USD 4.6/bbl.

 Breakthrough variant of half-green fuels. Author: David Judbarovski, systems engineering, principle inventor, retired. See my professional CV  shortly in Linkedin.com. judbarovski.blogspot.com, judbarovski@gmail.com . Abstract.  My variant is based on extremelly cheap solar and/or wind energy as a result of many   years of my research and development. The said breakthrough cheap fuels can be produced domestically and cheaply, and it allows to integrate huge amount of  renewable energy in national grids, being now a sore and unsolvable problem.     (1) C + H2O = H2 +  CO + 176 KJ. (2) 2 C + 2 H2O = 2 H2 + 2 CO + 352 KJ. (3) CO + 2 H2 = CH2 + H2O - 226 KJ. And summarised in CH2 = 2 C + H2O - CO (sold) +  352 KJ (heat) - 226 KJ (electricity sold) = 2 * 12 * 120 + 352 * 4 / 3.6 - 28 * 50 - 226 * 0.3 efficiency heat in electricity * 0.033 local tariffs / 3.6 = 3280 - 1400 - 600 = USD 1280. So 1280/ 14/ 7 =   USD 12.8 / bbl of ...

 H2 cost minimisation. Author:  David Judbarovski, systems engineering, principle inventor, retited. See my professional CV shortly in Linkedin.com.  judbarovski.blogspot.com,  Judbarovski@gmail.com  Abstract.  C + H2O = CO + H2 - 176 KJ,  176 * 4 / 3.6 = USD 200.   Q (H2) + 200 = (Q(C) * 12 - Q(CO) *28) / 2.  If C = USD 120/ ton, СO = USD 50 /ton,  H2 = practically free. ,

 Breakthrough variant of half-green fuels. Author: David Judbarovski, systems engineering, principle inventor, retired.

Abstract.  My variant is based on extremelly cheap solar and/or wind energy as a result of many   years of my research and development. The said breakthrough cheap fuels can be produced domestically and cheaply, and it allows to integrate huge amount of  renewable energy in national grids, being now a sore and unsolvable problem.  (1) C + H2O = CO + H2 - 176 KJ , (Fischer-Tropsch process) - 176 * 4 / 3.6 = USD 200.0. 12 * USD 120 / ton = USD 1440, so  CO + H2 = 1440 + 200 = USD 1640, so CO = 1640 - 2 * 100  = 1440, so CO = 1440 / 28 = USD 50.0 /ton CO here,  being valuable by-product can be sold. (2)   CO + 2H2 = CH2 + H2O + 226 KJ. Here CH2 production consumes C = 12 * 12O and 179 KJ  = USD 1640 minus surplus CO ...
