Taarnby: city of smart solutions
The energy facility in Taarnby near Copenhagen, Denmark, is the world's first to combine district cooling and heating with wastewater, ground source cooling and a cold-water storage tank, resulting in cost-effective low-carbon energy for the district it serves.
- the profitability of establishing a district cooling system based on a large-scale heat pump installation and a cold-water storage tank
- the benefits of using the same heat pump installation in combination with ground source cooling and wastewater
- district cooling, wastewater, and ground water as components of the existing integrated energy system in Copenhagen
- a heat pump installation, which is simultaneously connected to a 2,000 m3 cold-water tank and the district heating system, allowing for optimised energy production considering electricity prices as well as the alternative heat production costs of all plants producing heat for the Greater Copenhagen district heating system
- lower impact on the environment through reduction of noise, vibration and use of space for individual cooling equipment
Taarnby’s smart heating and cooling system
- : 4.5 MW
of cooling
The heat pump installation generates 4.5 MW of cooling and 6.2 MW heating. The Aquifer Thermal Energy Storage(ATES) plant utilising ground water is expected to generate an additional 2.8 MW of cooling. On a hot day, the total cooling capacity from the heat pumps, ground water, and storage tank is 10 MW
- : 2020
In 2020, the Taarnby project received the Heat Pump City of the Year award from the European Heat Pump Association in the DecarbIndustry category, which is given to the most innovative industrial heat pump project in the market
- : 2021
In 2021, the EU selected the Taarnby project as one of eight cases for a study on integrating renewable and waste heat and cold sources into district heating and cooling. The Taarnby case was chosen as a remarkable example of smart sector integration, illustrating the key role that district heating and cooling systems can play in building integrated energy systems
