Aalborg CSP

What Aalborg CSP does

Aalborg CSP A/S is a privately held Danish engineering and consulting firm, founded in Aalborg in 1988, specialising in high-temperature thermal energy systems for energy and industrial decarbonisation. Its core technical domain covers Concentrated Solar Power (CSP), molten salt technologies operating up to 850°C, thermal fluid heat exchangers and steam generation, and high-temperature thermal energy storage (TES) at temperatures from 100°C to 850°C. The firm holds proprietary Header-Coil heat exchanger technology commercialised through its joint venture Alfa Laval Aalborg Header-Coil A/S, supplying leakage-free, cyclic-duty heat exchangers for CSP and thermal storage applications globally, and has delivered more than 1,700 MWth of solar installations across 30+ countries.

The company sells exclusively through direct enterprise engagement, delivering a full lifecycle of services: feasibility studies, pre-engineering (FEED), detailed engineering and design, procurement management consultancy, and construction and commissioning management consultancy. It explicitly does not take EPC contracts, positioning itself as a supplier-independent engineering advisor serving coal power plant owners, oil and gas utilities, renewable energy developers, industrial heat operators, and SMR developers. Revenue is generated through fee-for-service engineering engagements and participation in EU-funded R&D programmes (Horizon Europe, Horizon 2020, EUDP, Interreg). Following the June 2026 divestiture of its Low Temperature Division to Alois Müller Beteiligungs GmbH, the firm now operates with approximately 30 employees across headquarters in Aalborg (Denmark) and an R&D and operations centre in La Rinconada, Seville (Spain), under CEO Peter Badstue Jensen and CFO Per Kirk, both active shareholders.

The firm's differentiator is the combination of supplier independence with nearly four decades of hands-on operating plant experience across CSP, molten salt, and thermal storage, supported by ISO 9001/14001/45001 certifications and demonstrated capability to deliver to nuclear-grade standards. Strategic priorities as of 2025-2026 include coal-to-Carnot battery conversion, SMR thermal integration, industrial process heat decarbonisation across the 150°C-850°C range, and modular salt tank systems for carbon capture via the July 2026 Mantel partnership.

Direct peers

• SENER: Spanish engineering and technology group with deep CSP and concentrated solar plant expertise, including turnkey and EPC roles on major projects like Noor Ouarzazate and DEWA. Direct competitor for CSP engineering contracts and molten salt thermal storage design work in the same geographies as Aalborg CSP.
• TSK: Spanish EPC contractor specializing in thermal power plants, including CSP and combined cycle. Competes with Aalborg CSP for steam generator systems, heat exchangers, and balance-of-plant engineering across CSP and combined heat/power projects.
• BrightSource Energy: US-based CSP technology provider developing utility-scale solar thermal plants with thermal storage. Direct peer in the CSP power tower space where Aalborg CSP supplies steam generators and molten salt components.
• SolarReserve: Developer of utility-scale CSP plants with molten salt thermal storage (e.g., Crescent Dunes). Comparable to Aalborg CSP in combining CSP generation with long-duration storage and serves overlapping utility and developer customers.
• Suntrace: German-based CSP and solar process heat engineering consultancy developing projects in MENA and emerging markets. Closely comparable business model to Aalborg CSP — engineering-led, supplier-independent, focused on CSP feasibility and pre-engineering.

Emerging players

• Brenmiller Energy: Israel-based provider of thermal energy storage solutions (bCR heat storage) for industrial and power applications. Comparable to Aalborg CSP's molten salt storage offering but with proprietary solid-media technology and a different deployment model.
• Rondo Energy: US-based industrial heat decarbonization company using thermal storage and electric heaters to replace fossil boilers in factories. Adjacent to Aalborg CSP's industrial heat process solutions — same end-customers, different technical approach and geography.
• Copenhagen Atomics: Danish thorium molten salt reactor developer partnering with Aalborg CSP on PUMP HiTS and Indonesia green ammonia. Not a direct competitor but a closely-linked counterpart whose progress both creates opportunity and signals the firm's positioning in frontier nuclear.
• Kyoto Group: Norwegian thermal storage company (HeatCube) commissioning Aalborg CSP's Header-Coil heat exchangers for PTXSALT projects. A customer today but a peer in the industrial-scale molten salt storage space where both target district heating and industrial heat decarbonization.

Broad incumbents

• Siemens Energy: Global energy technology incumbent supplying turbines, steam generators, grid technology, and CSP solutions. A broader incumbent where Aalborg CSP competes as a specialized niche engineering firm on steam generation and thermal storage subsystems.
