World’s largest CO2-based seawater heat pump starts operations
MAN Energy Solutions has successfully commissioned the first unit of its industrial-scale heat pump in Esbjerg, Denmark, marking the delivery of its first heat. On the other side of Denmark, testing has begun of a full-scale ammonia engine.Operated by DIN Forsyning, the new heat pump plant will supply approximately 280,000 MWh/y of climate-neutral heat to the district heating networks of Esbjerg and the neighbouring town Varde, covering the heating needs of 25,000 households.
Located at the Port of Esbjerg, the plant harnesses renewable energy from nearby wind farms and heat from seawater.
With a total heating capacity of 70 MW, the CO2-based heat pump system is thought to be the largest of its kind in operation. It operates in tandem with a 60 MW biomass boiler that uses sustainable wood chips and a 40 MW electric boiler plant, which serves as a peak and backup load facility.
Full-scale ammonia engine begins new chapter
In other news, MAN Energy Solutions has announced that the development of its ME-LGIA (Liquid Gas Injection Ammonia) engine for marine applications has entered a new phase with the start of testing of a full-scale, two-stroke engine running on ammonia at its research centre in Copenhagen.
Ole Pyndt Hansen, Head of Two-Stroke R&D, MAN Energy Solutions, comments: ‘Having already completed more than 12 months of testing on a single cylinder running on ammonia, it’s a significant milestone to be able to step up to full-scale engine testing. We have been busy with the conversion process over the past few months, including ensuring that all safety provisions work according to our requirements. We are now ready for the next phase that will focus on, among other parameters, combustion and emissions, engine-tuning, atomiser testing and control-system verification.’
Testing is provisionally set to continue until mid-2025.
