Task 45 Highlights 2014February 2015 - PDF 0.49MB
Large solar heating and cooling systems are very cost effective in some applications, for example supplying heat to an existing district heating system. The market for “Solar District Heating Systems” is developing fast in northern Europe as well as in China – and has big potential in other places. Use of seasonal storage and heat pumps makes it possible to obtain a high solar fraction (> 50%) and to interact with and level out dynamics in the electricity grid (these dynamics are increasing due to increased supply from wind turbines and PV systems). Solar district heating systems are getting rather large (a 50 MW solar collector field with a 200,000 m3 water pit storage in Denmark will begin operation in the spring of 2015).
