Throughout the past decades, Bulgaria’s governments have focused almost exclusively on large conventional energy projects, such as nuclear plants or gas and oil pipelines, whereas small and decentralised renewable energy systems haven’t received much attention from politicians. But the large-scale projects are complex and expensive, so none of them have come to fruition. This is where the most current study by the Bulgarian Institute for Zero Energy Buildings (IZEB) comes in: It sends an important message to all stakeholders by describing a way to keep the entire Bulgarian capital of Sofia and its 1.2 million inhabitants warm without the use of any combustion fuel.
While the solar thermal industry has had a difficult time in several EU countries, the solar district heating (SDH) community is still growing: 180 participants from the EU, South Korea and China attended the 4th International Solar District Heating Conference, which was held at quite the peculiar location this year – Denmark’s Legoland – and was organised under the auspices of the Horizon 2020 project SDHp2m…from Policy to Market. The introductory session of the conference was really inspiring. Thomas Pauschinger, Project Coordinator of SDHp2m, underlined how Denmark’s construction of plants in the 100 MW range was proof of the country’s solar thermal strategy of “think big”. Impressive results, even more so if one takes the statement by Kim Behnke, Deputy Director General of Dansk Fjernvarme, the Danish District Heating Association, into account that “the Danish solar dream started just ten years ago”. Denmark’s solar installations have become so famous that they have even been turned into brick models at Legoland. The photo shows the 13 MW solar field in Braedstrup, Denmark.
