About Solar Millennum AG:
Solar Millennium AG is an innovative project development and technology company in the renewable energy sector which is active around the world. Together with its subsidiaries and partners, Solar Millennium AG plans and constructs solar thermal power plants, and has specialized in two technologies in this field. Firstly, it is a technology provider for parabolic trough power plants, a proven and reliable technology in which Solar Millennium is regarded a world leader. Further, the company develops solar chimney power plants with the objective to make this technology marketable. The main focus of current projects is Spain, the USA and China.
About the technology:
Solar thermal power plants generate electricity using the heat captured from solar radiation. In a parabolic trough power plant, trough-shaped mirrors focus the incident solar radiation onto a pipe in the focal line of the collector. A heat transfer medium in the pipe is heated, and this generates steam in the power block section using heat exchangers. The steam is then used to operate a turbine which generates electricity in the same way as in conventional power plants. Integration of a thermal storage system means the availability of the electricity can be planned. Therefore, the solar power plants can also generate electricity after sunset.
