The PHOEBUS demonstration plant has been supplying the Central Library of Forschungszentrum Julich (FZJ) with solar-generated electric energy all year round and independent of the public grid since 1993. The central task was to test the required stor

The fluctuating offer of renewable energies and their, in most cases, not synchronous use make it necessary to develop processes of energy storage both for short-term, relatively small amounts of energy with great power fluctuations and for long-term

For a PV generator installed at the facade of an inner courtyard, the irradiance losses due to shadowing have to be assessed and the PV modules must be connected in such away that the energy losses accumulated during the year are minimized. Besides d

The performance of a two-stage metal hydride hydrogen compressor has been investigated. The two reactors of each stage are filled with 5 kg TiMn2-based metal hydride material each. In the first stage hydrogen is absorbed at 10 °C and 5 bar. Desorpti
