The COOL DH project ended in September 2022. The objective of COOL DH was to support cities in their endeavor to plan and deploy new, efficient district heating and cooling (DHC) systems and extend, refurbish existing ones to higher standards. Thus allowing greater uptake of renewables, recovering of excess heat or cold while improving the overall efficiency of the systems.
The Brunnshög district is an ambitious project, with the goal to offer the best research and innovation environment in the world and to showcase sustainable urban development. Fully developed the district will have 40,000 inhabitants and employees before 2050. Low-grade surplus heat recovered from the research facilities of ESS and MAX IV will heat the entire district.

In 2015, the district heating supply consisted of 51 % fossil free energy from biomasses, the renewable part of waste, solar, geothermal energy etcetera. Using a larger share of low-grade surplus heat and increasing system efficiency is an important step of reducing emissions even more.
