Incremental changes can result in substantial cost reductions
The technologies for producing electricity from solar thermal energy can be divided into three main categories:
- Parabolic trough and Fresnel systems
- Central receiver systems, including the solar updraft tower
- Parabolic dish systems, usually combined with a Stirling heat engine
The first commercial CSP plant, which was built in California in the 1980s, used the parabolic trough concept. It has a total capacity of 354 MW. For many years, this was the only large scale CSP plant in the world. Elsewhere, only small demonstration plants were built, as the high investment cost hampered further deployment.
