Role of hydrogen and fuel cells in renewable energy systems

摘要

The special requirements of fluctuating renewable energy sources include storage, backup or import/export arrangements. This paper will focus on the possible role of hydrogen as an energy carrier in an energy system with large contributions from renewable energy sources such as wind power or solar electricity. In particular, it will be shown that the structure of the transportation sector may develop in such a way, that the renewable energy and hydrogen type of solution becomes particularly attractive. This involves fuel cell driven vehicles and technology for introducing infrastructure changes at a minimum cost.
