MAN ETES (Electro Thermal Energy Storage)

A tri-generation energy management solution for simultaneous storage, use and distribution of electricity

MAN ETES stands for Electro-Thermal Energy Storage; it produces and stores heat, cold and electricity at a large scale. Therefore, it is the ideal system for the increasingly important "Sector Coupling", meaning the merging of energy suppliers and consumers. MAN ETES helps municipalities, institutions and companies to reach their goal of CO2 neutrality by providing a system that is completely environmentally friendly and decarbonizing. In contrast to the majority of the competition, this solution uses CO2 as a refrigerant, which is neither toxic to its environment nor flammable as well as inexpensive and easily accessible. Furthermore, the technology solution is powered by MAN's HOFIM® compressor with an integrated expander, which is hermetically-sealed and operating without lube oil. MAN ETES, with electrical inputs from 2 to 14 MW, can provide hundreds of MWh of thermal energy per day and unit with temperature levels between 0° and 150°C.

Implementation Stories

MAN ETES (Electro Thermal Energy Storage) by MAN Energy Solutions Schweiz AG
Implemented by DIN Forsyning in Esbjerg (Denmark) in 2023

DIN Forsyning is currently commissioning this heat pump technology in the Danish port city of Esbjerg. The turnkey solution from the company will include two ETES heat pump units to help decarbonize Esbjerg’s heat supply and replace today’s coal-fired power plant. These will be installed in a new district heating plant based on the operating principle of a heat pump, but on a large industrial scale. The deployment of the heat pumps will avoid 100’000 tons of CO2 emissions per year, and hence support Esbjerg in meeting its 2030 carbon neutrality target, which is aligned with Denmark’s goal to phase out coal.


With a total heating capacity of 50+ MW, the plant aims to supply about 100,000 local residents with about 235,000 MWh of heat per year.


The environmental benefits

  • Produces heat and cold with up to 80 MW thermal (heat & cold) per heat pump unit
  • CO2 neutral, provided it is operated with green power
  • When dismantled - after 35+ years of lifetime - can be recycled by 90+%

The Financial benefits

  • Average payback periods in 5 to max 10 years (lifetime of 35+ years)
  • 100% savings on CO2 tax over any other systems, which are still emitting CO2 (fossil fuel burning), including biomass CHPs
