摘要

For a successful market roll-out of hydrogen technologies, the build-up of a reliable hydrogen infrastructure is a crucial precondition. Fueling stations for fuel cell cars, industrial consumers as well as decentralized energy applications will demand for large amounts of hydrogen to be provided at the right place and at the right time. For instance a future fueling station capable of providing hydrogen for the same amount of driving kilometers than an average gasoline station today, will consume about 1,000 - 2,500 kg of hydrogen per day [1]. Trailers with today's state of the art compressed-gaseous-hydrogen (CGH2) can carry ~350 kg of hydrogen and would therefore result in a very high frequency of delivery runs. The same holds true for the supply of the chemical industry with hydrogen, where the costs for transportation dominate the total costs of supply due to high complexity of CGH2 handling and the low storage density. Liquid Organic Hydrogen Carrier [2] render the complex handling of hydrogen gas unnecessary by chemically storing hydrogen within dibenzyltoluene [3], a non-toxic, non-explosive heat transfer oil, well-known in industry. A tanker truck with LOHC can transport up to 1,800 kg of hydrogen.
