One of the biggest power-to-heat facilities in Germany began operating Sunday (December 16, 2018) in Hamburg’s Karolinenviertel. The “Karoline” electric boiler indicates the potential of sector coupling. Wind power can be converted into heat and fed into the district-heating network. The electric boiler, operated by Vattenfall, also secures the heat supply in particularly cold weather or when other supply systems malfunction. The plant has a capacity of around 45 megawatts and can supply 13,500 apartments with environment-friendly heat.
Hamburg on course to energy transition
CO2-free industrial heat or energy-saving electric boilers are just two projects designed to keep the Hamburg Metropolitan Region on track towards the energy transition. Coupling different sectors for an energy system of the future is the prerequisite. Great energy efficiency, low-CO2 heating networks and renovating buildings are crucial to achieving climate protection targets.
Great potential of heat supply for saving C02
The eastern part of HafenCity is to be supplied with CO2-free industrial heat from the Aurubis copper smelter and in time for the start of the heating period. The multi-metal company decouples heat that is generated in a secondary process of extracting and purifying copper. It will be supplied to eastern HafenCity via a 3.7 km long heat pipeline. Up to 20,000 tonnes of CO2 could be saved every year in this way.
