Last week, the Danish Energy Agency (under the auspices of the Danish Ministry of Energy, Utilities and Climate) announced it had allocated funding to install 13 large heat pumps at 11 small district heating networks in Denmark.
The heat pump projects will likely use ammonia as the refrigerant due to Denmark’s strict f-gas legislation. The Scandinavian country began to phase down HFCs in 2001, five years earlier than the EU as a whole (see Accelerate Europe Issue 7 to learn more).
“To our knowledge, all of the heat pumps are based on ammonia as the refrigerant due to HFC regulations in Denmark, which only allow the use of a maximum 10kg HFC per unit,” Thomas Capral Henriksen – chief consultant at Dansk Energi (the Danish Energy Association), which represents energy companies in Denmark (including producers and distributors of electricity and large producers of district heating) – told Accelerate Europe.
