High-temperature thermal energy storage
The ability to store heat at high temperature and dispatch it on demand is the engineering capability that connects most of the work Aalborg CSP does.
A coal plant repurposed as a Carnot battery. A renewable energy producer converting curtailed output into dispatchable revenue. An SMR developer integrating storage into the power cycle. An industrial operator buffering process heat supply.
Unlike battery storage, high-temperature thermal storage does not degrade with cycling, operates at the temperatures industrial and power generation applications actually require, and can be sized for hours or days rather than minutes. At scale, it is significantly more cost-effective per unit of stored energy, and those advantages matter most precisely where the energy transition needs storage most urgently.
Aalborg CSP's engineering depth in this area spans molten salt systems, solid media storage, and emerging configurations being advanced through our R&D programmes including REACT-EU, HELIOTROPE, SunCharge, REINVEST, and TREASURE. The technology we recommend depends on the application. We assess what the evidence shows.
