Aalborg CSP has received the order to supply its header-coil heat exchanger for steam generation and molten salt circulation system for the Kyoto Group project to establish thermal energy storage at Aalborg Forsyning’s green test center at Nordjyllandsværket. We will store electricity from, e.g., wind turbines in a modular storage solution. The energy, on-demand, is converted back to steam for green district heating and potentially for green power production for the residents of Aalborg city.

The PTXSALT plant in Aalborg will be the first in Northern Europe.

However, the molten salt technology has been utilized within the CSP (Concentrated Solar Power) industry for plants in Spain, the Middle East, and the US for decades. Experience from existing molten salt storage and header-coil equipment has proven the technology to be scalable, more economical, and bankable than other large-scale energy storage technologies commercialized to date.

Aalborg CSP will be working closely with Kyoto Group on their entire HeatCube system.

The Aalborg CSP scope of the project consists of supplying the heat exchanger of the header-coil type for steam generation and the design of the integrated molten salt and steam system connected on one side to the molten salt storage tanks and on the other side to the header-coil steam generator. In doing so, Aalborg CSP will be working closely with Kyoto Group on their entire HeatCube system to store excess renewable electricity in a thermal battery with molten salt (PTXSALT) and generate steam when energy is needed in terms of district heating for the city.
