Aalborg CSP received the order to supply its Header Coil heat exchanger for steam generation for the Kyoto Group thermal energy storage project in Denmark – a PTXSALT plant.


Client:       Kyoto Group
End user/Owner:         Aalborg Forsyning
Location:    Green test center at Nordjyllandsværket, Aalborg, Denmark
Status:    Under construction
Technology:    Heat exchanger for steam generation

The header-coil heat exchanger technology from Aalborg CSP is designed to withstand high pressure, high duty, and transient operation. Moreover, the technology meets the large requirements for thermal performance and a fast ramp-up as well as ensures high long-term reliability and efficiency under cyclical load conditions, which is a critical point of focus for PTXSALT plants. Besides supplying the header-coil heat exchanger for steam generation, Aalborg CSP will work closely together with Kyoto Group on their modular HeatCube storage concept - a thermal battery with molten salt.

Electricity from wind turbines will be stored in a molten salt storage and, on demand, converted back to steam, to be used for green district heating and potentially for green power production for daily and weekly load shifting in the electricity grid as well as for constant power supply for well-known PTX technologies. Combined, the two technologies can be considered a green base-load plant and reuse parts of the coal fired power plant’s existing infrastructure.
