The STORM project – Developing an innovative District Heating & Cooling (DHC) network controller to increase the use of waste heat and renewable energy sources and boost energy efficiency at district level. The project tackles energy efficiency at district level by developing an innovative district heating & cooling (DHC) network controller. The project partners have developed a controller based on self-learning algorithms, which is currently experimented in the two STORM demo sites. The developed controller will enable to maximize the use of waste heat and renewable energy sources in DHC networks. The STORM project is funded by the European Union’s H2020 Programme. The controller has been implemented in 2 demo sites, Mijnwater BV in Heerlen (NL) and Växjö Energi in Rottne (SE), where the resulting energetic, economic and environmental gains are assessed.
