ABSTRACT

The computer simulations make use of wind energy data from one Danish location, which on a worldwide scale would be characterized as medium suited for wind energy production. On a short timescale the output from a wind energy generator (WEG) must be expected to exhibit substantial fluctuations. An electricity-producing WEG system with hydrogen storage may be integrated into the complete energy supply system in a way, which substantially diminishes the losses associated with the hydrogen cycle. The mode of operating the storage facility is that power is drawn from the storage if load exceeds power generation, and is deposited into the storage if power generation exceeds load. The WEG power duration curve, in the absence of any storage facility, is considerably less favourable than that of the nuclear reactor. Including initial fuel, the capital cost of a nuclear plant may be only slightly lower than that of a WEG system with short-term storage which delivers the same average output.
