Saipem and Capsol Technologies have formed a non-exclusive partnership to promote large-scale deployment of hot potassium carbonate solvent-based carbon capture, aiming to advance decarbonisation efforts at hard-to-abate industrial sites.
Saipem and Norwegian capture specialist Capsol Technologies have agreed a non‑exclusive partnership to pursue industrial-scale carbon capture projects using hot potassium carbonate (HPC) solvent technology, a move intended to broaden market access for the two firms and speed deployment of capture at hard‑to‑abate sites.
Under the cooperation framework, Capsol will contribute its HPC capture process and modular technology packages while Saipem will provide project delivery, engineering, procurement and construction capabilities. According to Saipem, the arrangement is designed to offer industrial emitters an integrated, standardised route to implement HPC‑based CO2 capture, including optimised designs and execution services for large facilities.
The alliance builds on an existing working relationship: Capsol’s technology is already selected for the large Bioenergy with Carbon Capture and Storage (BECCS) plant Saipem is building for Stockholm Exergi in Sweden. Saipem says that project, for which it has received a full notice to proceed and a contract valued at about €600 million, will capture 800,000 tonnes of biogenic CO2 a year from the Värtaverket biomass cogeneration plant and includes CO2 storage and ship‑loading systems. Industry observers view the BECCS contract as a proving ground for scaling solvent‑based capture solutions for challenging industrial heat and steam profiles.
For Capsol, partnering with established engineering, procurement and construction (EPC) houses is central to a strategy of making carbon capture easier to procure and install; Saipem’s global project execution footprint is expected to help take the company’s offering to a wider set of emitters. The companies say the agreement allows them to pursue joint bids and tenders where mutually appropriate, signalling an intent to target not only power and waste‑to‑energy plants but also heavy industry applications where HPC chemistry can be attractive for cost and energy performance.
Saipem’s approach to post‑combustion capture already includes multiple technology routes. In 2023 Saipem agreed a general licence to deploy Mitsubishi Heavy Industries’ KM CDR absorption processes, reflecting a strategy of combining third‑party capture technologies with its EPC capabilities rather than relying on a single proprietary process. The new Capsol tie‑up therefore broadens Saipem’s technology toolkit at a time when large emitters are assessing capture options against differing flue gas compositions, thermal integration constraints and cost targets.
The partnership’s commercial impact will hinge on a number of market and technical factors. Industry data and project experience indicate that solvent choice, integration with plant steam and heat systems, modularisation to reduce on‑site construction time, and proven delivery track records are decisive in customer procurement. According to Capsol, its HPC route offers a competitive capital and operating cost profile, but commercial uptake will depend on project‑by‑project engineering, the availability of transport and storage solutions, and national policy support such as carbon pricing, subsidy schemes or contractual revenue guarantees for captured CO2.
For large industrial emitters and decarbonisation planners, the Saipem–Capsol agreement signals growing supply‑chain maturity for solvent‑based capture and reinforces the broader trend of EPCs knitting technology licences, modular suppliers and financing partners into turnkey offers. Whether the partnership accelerates deployment at scale will be revealed through forthcoming bid activity and the rollout of projects that follow the Stockholm Exergi example.
