Danish multi-utility firm, DIN Forsyning, has commissioned MAN Energy Solutions to provide a turnkey know-how answer for warmth era, that includes two ETES heat-pump methods.

These can be put in in a brand new district heating plant based mostly on the working precept of a warmth pump – however on a big, industrial scale.

With an general heating capability of 50MW, the plant will provide round 100,000 native inhabitants with roughly 235,000MWh of warmth yearly.

The location on the Port of Esbjerg will allow using renewable energy from close by wind farms and seawater as a warmth supply for the era of heating vitality. The new district-heating plant will thus assure an emission-free various to the town’s present, coal-fired energy plant, which at current offers roughly half of Esbjerg’s district heating and is scheduled for closure by April 2023.

“The deployment of the ETES warmth pump methods from MAN Energy Solutions will assist us to make sure an environmentally pleasant and economically environment friendly heat-supply for the inhabitants of the town of Esbjerg. By decarbonising the warmth provide, we’re making an allowance for Denmark’s aim of phasing out coal whereas making certain the environmental preservation of Denmark’s Wadden Sea, which is a UNESCO World Heritage Site,” defined Anders Linde, chairman of the Board of DIN Forsyning.

ETES know-how

ETES know-how allows the exploitation of extra energy from renewable vitality sources, which may have a useful impact on the effectivity of energy manufacturing from wind and photo voltaic vitality and can additional cut back the necessity for fossil energy vegetation. In addition, the operational flexibility of the heat-pump answer makes it doable to generate electrical balancing energy within the brief time period, and subsequently to take care of stability on the grid.

The key, revolutionary function of ETES know-how is using toxicologically and environmentally secure CO2 as a refrigerant for your complete system cycle. The CO2-based heat-pump plant in Esbjerg would be the largest of its form ever used on the earth.

The scope of provide for the venture in Esbjerg covers your complete heat-pump system, together with the warmth exchangers, the piping for the CO2 and seawater cycles, the water pumps in addition to infrastructure supplied by ABB Switzerland and ABB Denmark.

The core factor is represented by two oil-free hermetically-sealed HOFIM® motor-compressor items with built-in expander, that are developed, produced and examined by MAN Energy Solutions in Zurich (Switzerland). The absence of the dry gasoline seal system and the entire oil system in addition to using a high-speed motor and energetic magnetic bearings leads to an emission-free compression system with a small footprint.

The primary precept of the know-how is the conversion vitality into thermal vitality, which is saved within the type of scorching water and ice in insulated reservoirs. The electrothermal course of not solely permits the distribution of the generated warmth and chilly to customers based on demand and margins, but in addition affords the choice of changing it again into electrical energy as an extra utilization variant.
