Press release - The largest seawater heat pump in Denmark is to be delivered from Switzerland
The danish heating company DIN Forsyning in Esbjerg has reached an important milestone in replacing heat supplied from the coal fired power station by placing contracts for the two main new production units located to be at Esbjerg Harbor.
In their 2030 strategy DIN Forsyning is pursuing a 100 % fossil free heat production with zero loss of applied resources. With two major contracts for a seawater heat pump and a biomass boiler plant with flue gas condensation the goal is much closer.
The world’s largest seawater heat pump based on CO2 provided by MAN Energy Solutions
MAN Energy Solutions Switzerland Ltd will deliver the 50 MW ETES seawater heat pump system to DIN Forsyning in Denmark. It will be the backbone in the future build at Esbjerg Harbor housing a green district heating production to nearly 100.000 inhabitants.
In the process of selecting the seawater-based heat pump it has been essential to DIN Forsyning and the Danish Environmental authorities to protect the sensitive environment of the Wadden Sea, which is a Natura2000 protection area and on the Unesco World heritage list.
The 50MW heat pump system will be the largest sea water heat pump in Denmark, and it will be the largest heat pump in the world using CO2 as refrigerant. In case of an unlikely leak the CO2 is completely harmless for the marine environment. Furthermore, the MAN Energy Solutions heat pump system has a high performance providing DIN Forsyning with a broad operation window.
The flexibility of the heat pump technology enables DIN Forsyning to take full use of the electrical grid connection delivering electrical balancing service on very short notice by increasing or reducing the electrical energy consumption.
The biomass boiler plant will be sister with plant in Espoo
To fulfill the heat demand of supply in the future heating production setup, a 60 MW biomass boiler plant will be built to operate in parallel with 50MW heat pump. The plant is to be delivered by the Finnish company KPA Unicon Oy. The biomass plant will be a sister to a plant in the city Espoo near the Finnish capital Helsinki.
It will be a bubbling fluid bed boiler with flue gas condensation which, in combination with heat pump, reaches 119% thermal efficiency. The boiler and flue gas condenser are a wastewater free solution – all condensate water is cleaned to the stringent requirement. The boiler and flue gas condenser are delivered as a turn-key contract by KPA Unicon Oy, Finland with a contract signed 22 December 2020.
The seawater heat pump and the biomass boiler plant are scheduled to be put into operation April 1th 2023, when the local Combined Heat and Power station shuts down.

The green heating for the future project
DIN Forsyning has launched a plan for converting the heat produced on coal to sustainable heat generation.
The project will combine many small and different solutions, linked to a central distribution network. It provides a flexible electricity-powered utilization of waste heat from waste to energy plant, local industry, wastewater treatment, seawater, future data centers, and eFuel plants.
It is a modular solution, as each part is only used, when reasonable – economically and environmentally.
