Aalborg CSP installed concentrated solar power plant in Denmark
Post date: 20/04/2017 - 13:24
Danish renewable energy company Aalborg CSP developed a concentrated solar power (CSP) plant to provide the city of Brønderslev with sustainable heating, but it will also enable power production as an add-on to a biomass-fuelled organic rankine cycle (ORC) system scheduled for completion in the second half of 2017.
The plant has been operational since the end of 2016 and now reached full capacity. The 16.6 MWth solar energy plant is based on the CSP parabolic through technology consisting of 40 rows of 125 meters long U-shaped mirrors with an aperture area of 26,929 square meters. The mirrors collect the sunrays throughout the day and reflect them onto a receiver pipe, which sums up to 5 kilometer receiver tubes. This receiver pipe is surrounded by a glass vacuum tube to heat thermal oil with temperatures up to 330 degrees Celsius to drive an electric turbine to produce electricity. The solar heating system can alternate between providing combined heat and power at peak price periods, or exclusively deliver heat.
The achievement of the plant is supported by the Danish Government’s Energy Technology Development and Demonstration Programme (EUDP). Aalborg CSP was awarded the contract to develop and deliver the solar energy plant by the Danish district heating plant (Brønderslev Forsyning) in February 2016.
