Overskudsvarme HOFOR Novozymes Viegand Maagøe Waste heat

Heat pump uses heat waste in Copenhagen

Reference: Novozymes A/S and HOFOR A/S

How do you utilize heat waste to benefit all parties involved? With a holistic approach and close cooperation at all stages. 

Viegand Maagøe helped developing the project which distributes heat waste from Novozymes to HOFOR’s district heating network.

How we completed the assignment

Novozymes and HORFOR wanted to use heat waste from the production of enzymes at Novozymes’ production facility in central Copenhagen. The heat waste originates from fermentation processes and has so far been ventilated into the air via cooling towers. But now the heat should contribute to the district heating network in Copenhagen. Viegand Maagøe has taken part in the project from the very beginning as adviser for both Novozymes and the district heating company HOFOR.

Viegand Maagøe is responsible for:

  • preparation of feasibility studies and business cases
  • analysis of tax legislation and grant options
  • preparation of cooperation agreement between the parties involved
  • advice on various regulatory procedures
  • preparation of technical specifications fortender materials for heat pump and building
  • assessment and negotiation of contracts on heat pump systems and buildings
  • project management and supervision during implementation phase.

Due to the expiry of the Energy Saving Agreement in 2020, the project has had a tight schedule. So, the project faced a number of challenges which have been handled with great efficiency through close cooperation between all parties, and among other things secured the necessary regulatory approvals on time.

Contract period: 2019 - 2020

Results

The project will be completed within the planned time frame. A solid business case has been established and a technical solution selected.

A 4 MW heat pump will be installed at Novozymes. The temperature of the heat waste will be increased with the heat pump, so that the energy can be used for the district heating network. Delivery temperature is up to 80 °C.

District heating for 6,000 households in Copenhagen

Using heat waste, the heat pump will deliver approx. 30,000 MWh of district heating equivalent to the heat consumption for approx. 1700 households. The project is currently ongoing and the utilization of the heat is expected to be in operation in October 2020.

Global Goals

The project contributes to the 17 Global Goals for Sustainable Development:

SDG 7 ’Affordable and Clean Energy’
Ensure access to affordable, reliable, sustainable, and modern energy.

SDG 12 ‘Responsible consumption and production’
Ensure sustainable consumption and production patterns.

SDG 13 ’Climate Action’
Take urgent action to combat climate change and its impacts.
