Overskudsvarme HOFOR Novozymes Viegand Maagøe Waste heat

Heat pump utilizes industrial waste heat in the heart of Copenhagen

Reference: Novozymes A/S and HOFOR A/S

How do you utilize waste heat to the benefit of all parties involved? With a holistic approach and close cooperation at all stages. Viegand Maagøe helped in development of the project distributing waste heat from Novozymes into HOFOR’s district heating network.

How we solved the task

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

Viegand Maagøe are 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.

Do to the expiry of the Energy Saving Agreement in 2020, the project has had a tight schedule. Hence the project faced a number of challenges, which have been handled with great efficiency through close cooperation between all parties involved, 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 waste heat will be raised with the heat pump, so that the energy can be used for the district heating network. Delivery temperature is up to 80 °C.

Destrict heating for 6,000 households in Copenhagen

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 under construction 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:
