Improved design for giga-size pit heat storage
Denmark’s cost-effective, tried-and-true seasonal pit heat storage concept needs to be modified if it is to be implemented across Europe, since district heat temperatures are higher and groundwater may be only 5 to 15 metres from the surface.

Success factors in top SDH countries
In the last decade, Denmark, China, Germany and Austria played a leading role in the deployment of large solar thermal systems around the world. What country-specific factors helped these four achieve that level of market adoption and how support schemes and business models contributed to success has been the topic of a new review paper written by an international group of experts.

Seasonal pit heat storage: Cost benchmark of 30 EUR/m3
Denmark has had a steep – but successful – learning curve with regard to the cost and efficiency of seasonal pit heat storage, which is used to store sunlight in summer for heating purposes in winter. Take Sunstore 3, for example, a 60,000 m3 pit heat storage system built at a cost of 38 EUR/m3 of storage capacity in the town of Dronninglund in 2014: It has now reached a storage efficiency of more than 90 %.
