TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organic substance is natural gas, methane, pulverized coal powder, a coal slurry, peat and/or biomass. The fuel cell contains solid oxide or another type of membrane transparent for oxygen ions. The membrane separates a reaction zone where partial oxidation of the organic substance takes place and a volume that contains gaseous oxygen. The polymeric carbon suboxide is in the form of nanotubes. The carbon rich fibers are carbon nanotubes. The nonequilibrium plasma is low temperature plasma. The water is in the form of steam. Preferred Method: The elevated temperature and pressure corresponds to supercritical conditions. The method (M1) further involves producing hydrogen. The hydrogen is selectively removed through the use of a fuel cell which consumes hydrogen, or a hydrogen-transparent membrane. The method (M1) further involves storing hydrogen in the polymeric carbon suboxide. Consumption of hydrogen in a fuel cell results in electricity production. In the method (M2) the hydrogen is removed from the reaction mixture by conducting the reaction in the presence of membranes transparent for hydrogen or by using high temperature membranes with high oxygen conductivity. In the method (M2) the reaction is carried out at a pressure greater than atmospheric pressure or a pressure greater than or equal to 1.5 atmosphere and at a temperature of greater than or equal to 25 degrees C or greater than or equal to 80 degrees C. The method (m2) is carried out in a vacuum or non-oxidative atmosphere. In the method (m2) involves reacting at least one material selected from carbon or a hydrocarbon further produces hydrogen. The method (m2) further involves removing hydrogen from the carbon rich fibers. In the method (m3) the water or carbon dioxide is at an elevated temperature and/or, pressure. The temperature and pressure correspond to the supercritical conditions. In the method (m3) the elevated temperature is supported at least partially by heat generated from the oxidizing hydrogen in the fuel cell. The method (m3) is performed at least partially in a reactor. EXAMPLE - No suitable example is given.
