# DOE Concentrates on Solar Energy

The US Department of Energy (DOE) has announced a \$72 million project to further the development of concentrated solar power (CSP). The goal is to build an integrated test facility that can use concentrated solar energy to heat a working fluid to greater than 700°C and deliver it to a steam turbine system to produce electricity. Current commercial CSP systems work in the 300°C to 550°C range.
