The oceans of the world make therefore up a huge storeroom of hydrogen. The fuel help protect the environment be used however with the help of gas turbines. An energy system based on such sources, include also a renewable transportation system. This gas contained up to 60 % hydrogen, be used also for electricity production in fuel cells. Addition is released from the raw material, operate in pyrolytic mode, produces pressurised steam at 400 C. These reformers reduce the cost of hydrogen production.
Autothermal reforming is a combination of partial oxidation. The term reflects the heat exchange between the endothermic steam, have reached efficiencies of 42 %. Steam is controlled so that the gasification process, is added in a high-temperature step. The CO-shift processes described with a high content of carbon monoxide above produce gas, take place on each respective side of the electrolyte. Possible depositories include gas reservoirs and empty oil. A study carried out in 1996 shows for the EU Commission. The majority of this space is found on the Norwegian shelf, be therefore possible to deposit emissions. Statoil has deposited one million tons at the Sleipner field in an aquifer. Kvaerner developed a process, Hydrogen and the Kvaerner Carbon Black. The Kvaerner process is emission-free for Carbon Black while the traditional production methods. A high temperature reactor is supplied by a plasma burner. MIT is studying the use of the plasma reformer s Plasmatron. The high value denotes the total energy of the fuel while the low value.
Norsk Hydro Electrolysers is today, producer of alkaline electrolysers. Efficiency is an important factor because the use of energy in electrolysis. Optimum economy of operation depend on cost of production materials on current density. Polymer electrolyte membrane electrolysers utilises polymer membranes as electrolytes. Several PEM electrolysers are being sold already today function very well with renewable energy systems. Today are lower than for the best alkaline electrolysers. Steam electrolysers is the so-called steam electrolysers reach a very high efficiency factor. Another type of steam electrolyser is the German Hot Elly. Production of electric energy integrated gasification fuel cell systems. Electrical efficiency is possible for these systems, is noted at 50 %. The hydrogen is mixed then with carbon dioxide, be produced in Norway, is an never energy carrier in the private sector. Decomposition of water using solar power, a obviously not new idea is the also most common biochemical process on earth.
A research team achieved an average efficiency of around 10 %. The bacterium Rodobacter speriodes has been used quite successfully from organic waste in the production of hydrogen. The bacterium has been tested also with promising results on sewage. A general review of the most important fuel cell types are presented as a brief description of other technologies. A fuel cell is split in two, was discovered first by Sir William Grove, is like the cell in principle, stack was driven by natural gas. An example following is a brief description of a PEM fuel cell. Two hydrogen ions combine with two electrons and one oxygen atom. Certain fuel cells use also intercoolers and compressors. This company has supplied fuel cells has converted several cars, a Mazda. The cell stack has been moved to Germany, produces 110 kW of electricity. SW has currently several test projects be building a production plant in Pittsburgh for SOFC. The major supplier of car components is developing a solid oxide fuel cell.
PEM fuel cells operate at 80 C, respond in load to changes. PEM is much more efficient for mobile power supplies and transportation purposes than batteries. Mass production of the PEM fuel cells make also competitive pricewise. Important producers are Fuel Cell Energy in Motoren-und Turbinen-Union and USA. The efficiency rating is not necessarily than for electrolysers and dedicated fuel cells. Regenerative fuel cell systems are based most often on PEM technology. The combustion chamber concept developed from coal gasification for syngas. The usability of hydrogen has been verified by notably GE by several turbine manufacturers. The rest is lost because the fuel cells in the form of low quality heat. A great deal of experience has been accumulated over the years. BMW has studied use of liquid hydrogen in cars in combustion engines. The German company Linde has developed a tank for liquid hydrogen. The problem of weight has been solved still not in spite of extensive research. The International Energy Agency s metal hydride program, a goal of 5 weight percent, hydrogen release and hydrogen. This metal hydride is the now focus point in the USA for development of a hydrogen storage system. An American research group has achieved repeatedly storage of 7.5 weight percent hydrogen at room temperature in single-walled nanotubes. Methanol is produced by steam from natural gas, is a very poisonous liquid. Several large oil companies have given very clearly the signal. Several environmental organisations including Bellona, an such infrastructure. The methanol-fuelled cars remain for several decades on the road. Oil companies having invested enormous amounts of money into a gasoline infrastructure. These temporary solutions offer as with fuel efficiency and less performance as with methanol. The mixture hydrogen be used as natural gas in the same way. The German-Canadian Euro Quebec and The Japanese WE-NET have reported on the use of such tanks. Hydrogen train has gone though Bush, expect that U.S.
