First power-to-heat plant in Hamburg to convert wind energy into heat

Friday, March 8, 2019

Electric boiler in Hamburg will generate heat during peak-load periods and, in future, convert wind energy into heat to be used for district heating.

The largest power-to-heat plant to date in Germany officially entered service on 29 November 2018, but as early as September, the new plant supplied its first megawatt-hour of heat to the district heating network in Hamburg. The plant is intended to generate heat during peak-load periods and, in future, convert wind energy into heat to be used for heating purposes.

Project Manager Bernd Gross is pleased: "Delivering the first megawatt-hour enabled us to show that the new electric boiler is ready for use. This modern plant will also be able to convert wind energy into heat and therefore make a further contribution to sector coupling and the energy transition in the long term."

Reduced use of fossil fuels means fewer CO2 emissions

The plan is to use the plant in the event of a short-term surplus of energy from renewable sources. Wind energy can then be used to heat water that will be supplied to the district heating network.

"Generally speaking, it works like a giant continuous-flow water heater and enables us to reduce the use of fossil fuels to generate heat and cut CO2 emissions," Gross explains. Read more
