With this new system, Aalborg CSP continues its deployment of new projects with customised solutions based on the most efficient technologies tailored to fit individual energy needs. This range of solutions has now been extended to include heat pump systems.
In recent years, large electrical air-to-water based heat pumps have been established as a key technology within the Danish district heating industry as an increasing number of utility companies have integrated heat pumps as an important supplement to their existing district heating supply.
By incorporating electrically powered heat pumps in the district heating supply, higher levels of renewable energy can be utilised for thermal purposes creating integration and balance between energy systems. With a growing wind turbine capacity all over the world, large heat pumps will play a significant role in the continued global green energy transition as well as in Denmark’s quest to phase out fossil fuels by 2050.
The heat pump system will increase the reduction of the facility’s natural gas dependency as well as stabilise energy prices for customers. The system in Saltum will use outdoor air as the source for heat production in order to supply sustainable heating to 370 customers in the town of Saltum.
“We have the flexibility to match individual energy requirements with the right systems and technologies – such as a solar-thermal system, a heat pump or a combination” said Jes Donneborg, Executive Vice President of the Aalborg CSP Solar Thermal Plant division. “When entering a project, first step for us is always to understand the client’s energy needs in order to match them with the right technology and thus propose the most value-adding solutions. In Saltum, the client’s temperature and energy needs favoured a heat pump system.”
The system is customised to fit the district heating plant’s specific energy needs with a high efficiency (COP) thus lowering the cost of energy. With a capacity of 1.2 MW at 0 °C, the plant is capable of producing 8,000 MWh heat annually, thereby covering approx. 80 percent of the customers’ heat consumption.
When asked, why Aalborg CSP was selected for this project, chairman of Saltum Fjernvarme Ole Hejlesen responded that the company was attentive to customer needs and was easy to work with. The solution from Aalborg CSP also delivers the best long-term financial returns which in turn benefits district heating customers.
