Hydrogen Supply Over Long Distances Using Chemicals Description and Evaluation of a Technical System.

摘要

The problem of the transport of hydrogen has been studied. The basic concept was the following: where electricity is available at low cost as compared to European costs, it is possible to produce hydrogen by electrolysis, also at low cost; if it is possible to transport the hydrogen in Europe at costs which are not prohibitive, one would thus have in Europe a low-cost energy vector. That electricity is available at low cost true only in certain parts of the world which are either a long way from Europe and/or geographically and climatically difficult. In fact, it can be transmitted by pipeline in gaseous form but it cannot be transported in bulk by sea in liquid form (LH2) at normal pressure such as, for example, the liquefied natural gas, because of lack, at the present state of technology, of suitable ships. Also the transportation in relatively small tanks by special ships should be excluded because of the physical characteristics of hydrogen. These facts exclude sites of hydrogen production which are separated from the sites of use by the sea. Economics and some conclusions of hydrogen transport are presented. 15 refs., 7 figs., 13 tabs.
