Helsingborg and Mölndal, Sweden

The Swedish demonstrator is made up of two demo sites.

The City of Helsingborg

Helsingborg is a town in Scania, Sweden. The twon has 108,334 inhabintants and is Sweden's closest point to Denmark. Helsingborg is a scenic coastal city and is one of the oldest cities in Sweden. The twon is is a major regional centre of trade, transport and business.

The Helsingborg Demonstrator

The Helsingborg demo site consists of a newly built low-temperature sub-network that exploits a borehole seasonal thermal energy storage system with a centralised heat pump. In Summer, industrial surplus heat will charge the borehole storage. The network will space heating and domestic hot water to 4 residential buildings (110 apartments) and 1 office building. The office building will also be supplied with district cooling. The network consists of a 4-pipe distribution system that operates at 40°C to supply space heating, and at 60°C to supply domestic hot water.

The demonstrator aims to achieve the following goals:

  • Installation of a borehole seasonal thermal energy storage system
  • Installation of a centralised heat pump to meet the baseload energy demand of the buildings
  • Installation of a PV-T field recovering heat into the seasonal storage
  • Smart control implementation to exploit the cheapest heat sources between the DH and the borehole field according to the electrical and thermal (DH) energy prices

Business model and platform innovation for double-sided market

The Area of Mölndal

Mölndal is a part of the Gothenburg urban area on the west-coast of Sweden, and constitutes the administrative centre of Mölndal Municipality. The municipality has a population of 60,000, with 40,000 people inhabiting Mölndal proper.

The Mölndal Demonstrator

This demonstrator consists of a newly built low-temperature sub-network that exploits a borehole seasonal thermal energy storage system. A centralised heat pump is used for domestic heat and local heat pumps are used for hot water. The newly built DHC sub-network is connected to the existing DH network. The new DHC sub-network will serve a complex consisting of 1 historic factory building converted into a modern office, 2 new office buildings, 5 residential buildings (with apartments) and 1 hotel.

The demonstrator aims to achieve the following goals:

  • Installation of a borehole seasonal thermal energy storage system
  • Installation of a centralised heat pump
  • Connection to the existing DH network based on 100% biofuel
