Doring, H., Schmid, B., and Brazel, H. (2005) Overcharge at 3C Rate and 12V Limit for Fresh and Cyded Li Cells with Polyolefin and Separion Separators. Report No. RP-ZSW-05J005, Center for Solar Energy and Hydrogen Research, Baden-Wiirttemberg. 

The operation of the plant serves the purpose of a grid-independent electricity supply of the central library of the research center. Surplus solar energy in the summer season is stored as hydrogen gas and is re-converted into electricity in the wintertime. The daily balance of demand and supply is realized with the short-term storage battery with allows an operation for three days. The plant can be operated without personnel [27]. All plant components (electrolyzer, gas purification system, fuel cell, etc.) except the storage pressure tanks are located within a large experimental building (total volume - 20,000 m ) on a 7 m X 18 m area with a distance to the roof of 17 m. 

The process for hydrogen production by solar water splitting with quantum boost has been developed by Science Applications International Corporation (SAIC), San Diego, California, and the Florida Solar Energy Center at the University of Central Florida (FSEC-UCF), Cocoa Beach, Florida with the collaboration of the author s group (see Figure 9.22) [153],...

At the Florida Solar Energy Center, we have developed a new TCWSC that utilizes the photonic portion of the solar spectrum for the production of hydrogen and the thermal portion of sun light for the generation of oxygen. 

High thermal efficiencies can be achieved with properly designed catalysts. A pilot plant for this chemical heat pump system was constructed in Oarai, Japan, and successfully tested in 1994. A pilot plant driven by solar energy was realized at the Florida Solar Energy Center demonstrating an average yield of 180 ml/h of hydrogen (over several days).
