| Abstract: | Hydrogen technology . Hydrogen is used today on a large scale as raw material in chemical engineering and in the long term has tremendous potential as one of the most important secondary energy carriers. Hydrogen is produced with fossil and nonfossil primary energy sources from fossil and nonfossil primary raw materials. As an almost pollution-free secondary energy carrier, which is storable and transportable on a large scale, hydrogen can be used with nearly all energy utilization techniques fueled at present by natural gas, and products of petroleum and coal. Decisive influence on the introduction of hydrogen as energy carrier is exerted by the status and further development potential of hydrogen energy technology, cost of hydrogen production, and safety of a widespread use of hydrogen in the energy economy. |
