Trondheim's pilot addresses one of the city's most critical emissions sources — the waste-to-energy (WtE) plant that accounts for nearly 25% of direct GHG emissions while providing essential urban infrastructure for both waste management and energy supply. CCWaSte4NetZero advances carbon capture and storage (CCS) solutions for this facility, recognising that WtE CCS requires all levers of change: technological, financial, political, and social interventions. The project operates as a quadruple-helix partnership: Lunera Energi AS (Statkraft Varme AS before 1 Dec 2025) (the plant owner who takes final investment decisions), Trondheim Municipality (responsible for climate policymaking), and SINTEF (providing insight on CCS technology and project development across Europe).
