Cambridge-based carbon capture innovator Mantel has announced a Strategic Supply Agreement with Danish thermal engineering specialist Aalborg CSP.
Under the framework, Aalborg CSP will lead the engineering and development of a standardized, modular plant design for Mantel’s proprietary molten salt tank systems – a critical subsystem anchoring Mantel’s unique, high-temperature molten-borate carbon capture technology platform.
The primary objective of the partnership is to systematically dismantle the steep capital expenditures and supply chain vulnerabilities that frequently derail industrial carbon capture deployment.
By shifting away from traditional, highly volatile “stick-built” field construction, the two firms are pivoting toward a shop-fabricated, modular architecture. The resulting system is being engineered for turnkey packaging, consolidating critical instrumentation, fluid storage, and high-temperature induction heating operations into compact, road-transportable modules that can be manufactured offsite and rapidly assembled in the field.
Cracking the Cost-of-Deployment Barrier via Thermal Engineering
The strategic tie-up merges Mantel’s cutting-edge liquid phase carbon capture chemistry with Aalborg CSP’s decades of commercial experience managing molten salts across demanding concentrated solar power (CSP) and thermal storage applications.
Because Mantel’s carbon capture process operates at high temperatures to maximize thermodynamic efficiency, the structural integrity and fluid dynamics of its salt tanks are paramount to maintaining low long-term operating costs.
The standardized architecture will function as the primary, repeatable building block for Mantel’s commercial pipeline.

By lowering the engineering overhead required to customize carbon capture infrastructure for separate facilities, the company can deploy its technology cost-effectively across divergent industrial asset classes, including power generation, heavy manufacturing, and oil and gas refining.
According to Cameron Halliday, CEO of Mantel, perfecting the core carbon chemistry is only half the battle of building a scalable climate tech firm. “The whole system must be transportable and repeatable, deployment after deployment,” he said.
By embedding Aalborg’s manufacturing blueprint into its delivery model, Mantel is positioning itself to bypass standard field construction bottlenecks and bring a standardized, factory-line approach to heavy industrial carbon management.
