Aalborg CSP engineers the thermal systems that energy and industrial decarbonization requires, from first concept to operating plant.
We work across a temperature range of 150°C to 850°C, where the physics becomes more demanding, the system design more complex, and the margin for error smaller. This is where we have worked for close to four decades: across concentrated solar power, molten salt systems, steam generation, industrial process heat, electrification, and large-scale thermal energy storage.
What connects these applications is not a product. It is a discipline.
The engineering of systems that move, store, and convert heat at temperatures where most engineering firms stop. That depth is what allows us to work across markets as different as coal plant asset repurposing, oil and gas electrification, renewable energy storage, industrial process heat, and nuclear thermal integration. Not as a generalist, but as a specialist who has encountered most of these problems before, in one form or another.
We work independently of component suppliers. That means our engineering is always driven by what the project actually requires: the specific application, the specific constraints, the specific business case.
Our work begins where most engagements begin: with a study or feasibility assessment or a pre-engineering assessment: the engineering basis a project needs before decisions can be made and investment committed. From there, we work through detailed engineering and design toward delivery. Where the procurement process requires independent technical oversight, we provide that as procurement management consultancy - vendor selection, bid evaluation, and contract support with no supplier relationships to protect. And where clients need independent oversight through build and commissioning, we provide that too, as construction and commissioning management consultancy.
We bring the analytical depth of an R&D organisation and the delivery experience of an engineering contractor. Because most of our projects require both.
Founded in Aalborg, Denmark in 1988. Operating from Denmark and Spain, with projects delivered across more than thirty countries.
A note on our recent restructuring
In 2026, Aalborg CSP completed a strategic transition of its Low Temperature Division, which now continues independently under the name Aalborg Heat Cool Systems, acquired and fully owned by Alois Müller Beteiligungs GmbH.
The division, established in 2011, has developed into a strong and independent business within district heating solutions, including heat pump systems and Pit Thermal Energy Storage (PTES) lid technology, and is now positioned for further growth with dedicated ownership and focus.
For Aalborg CSP, this transition allows us to focus fully on engineering for high-temperature applications.
