Stockholm Exergi, a joint venture between Finnish utility Fortum and the city of Stockholm, is exploring the possibility of making the Swedish capital’s district heating the world’s first to become carbon negative.
As a first step, the company this spring will close its last coal-fired boiler for power and heat production at the Värtaverket combined-cycle plant in Stockholm.
Stockholm Exergi already in 2016 had replaced most of Värtaverket’s coal-based production with biofuels.
