A unique venture – surplus energy from a new data center in Sweden is transformed into district heating
Today GleSYS started supplying district heating to Falkenberg Energi. In this unique collaboration, surplus energy from the newly constructed data center on Sweden’s West Coast is recycled and used to generate district heating. The venture has the potential to heat 1,700 residential buildings while simultaneously reducing carbon dioxide emissions by 1,570 tonnes – every year.
The fast-growing data center industry currently accounts for two percent of the world’s annual carbon emissions and three percent of its electricity consumption. Just five years from now, the corresponding figures are estimated to be a staggering 5.5 and 20 percent, respectively.
The hosting company GleSYS represents a new generation of infrastructure providers offering efficient cloud solutions through modern and environmentally friendly facilities. Now the company has opened the West Coast’s largest data center, which is not only outfitted for heat recovery but is also powered by 100 percent renewable energy. The entire facility has been designed with a consistent focus on the environment and sustainability.
— With the increasing impact of the data center industry on the climate, it is more important than ever to be as sustainable as possible, even if it requires going the extra mile. Recovering the waste heat from our data centers is the biggest contribution we can make. In doing so, we’re taking on a leading role in the Nordic market, says Glenn Johansson, CEO of GleSYS.
In addition to the financial benefits of recovering waste heat from the data centers, the collaboration is also of great environmental value. By recovering waste heat, carbon emissions are expected to be reduced by the equivalent of 1,570 tonnes per year.
— The incorporation of this type of third-party supplier in the district heating network is a giant leap for heat recovery in Falkenberg, and benefits both the environment and the inhabitants of the municipality, says Bo-Anders Antonsson, CEO of Falkenberg Energi.
— By taking advantage of the waste heat from GleSYS' server halls, we increase the share of recycled energy in our heat production, which means that the municipality also limits its climate emissions, Bo-Anders continues.
The recovered heat has the potential to heat 1,700 residential buildings in the municipality, and the energy from the waste heat may amount to as much as 26 GWh annually – equivalent to 25 percent of Falkenberg’s total district heating production.
