Saipem offers comprehensive solutions across the entire CO2 value chain. They position themselves as a technology company with over 60 years of experience in EPC delivery and a commitment to sustainable solutions. Their Bluenzyme 200 solution offers a capacity of 75kt CO2 with Enzyme technology.
They claim competitive advantages based on the following:
Comprehensive service: Saipem builds on their 60+ years of relevant O&G EPC experience for the overall CO2 value chain from capture, pipeline and ship transportation, to storage and re-use. They are a service provider for all project stages.
Sustainability: Saipem claims to have the most sustainable solution on the market due to their use of non-toxic chemicals, mainly the natural enzyme carbonic anhydrase (CA). Adding enzymes does not increase safety risks either during normal operations or even in case of incidents.
Cost-effectiveness: Saipem claims their Bluenzyme capture technology secures 20%-30% savings due to their use of enzymes in the process. This is due to the need for only low-grade residual heat with temperature as low as 85C.
Before entering the Bluenzyme solution, the flue gas is compressed to an elevated pressure (1.). The flue gas travels trough a Quench Column where it is cooled down and hydrated.
2. Lean solvent CO2 absorption and Enzyme reaction
The CO2-rich flue gasses are transferred to the Absorber column (2.). There, the lean solvent and enzyme solution are introduced whence they bind the CO2 molecules from the flue gasses.
3. Enzymes to enhance CO2 absorption process
Saipem’s and Novozymes enzyme technology assists with CO2 capture. In essence, it accelerates the hydration of CO2 in K2CO3 and thus assures a high capture rate. The enzyme solution allows for lower energy requirement and usage for low-grade residual heat as low as 85C.
4. Rich solvent desorption
The CO2-laden solvent (2KHCO3) travels from the absorber tower (2.) to the desorber unit (3.). There it undergoes heat treatment and releases pure CO2.

Reference projects
St. Felicien Demonstration plant (2019)
The St. Felicien Demonstration plant, operational since March 2019, played a significant role in showcasing the potential of enzymatic carbon capture technology. Here’s a breakdown of the project:
2012:
CO2 Solutions Inc. and Resolute Forest Products announce plans to collaborate on a pilot project for carbon capture from a pulp mill flue gas.
2014:
Funding secured from the Canadian government and private investors.
2015:
Construction of the demonstration plant begins in Saint-Félicien, Quebec.
March 2019:
The plant becomes operational, marking the first commercial application of CO2 Solutions’ enzymatic capture technology.
2019 – 2021:
The plant successfully captures and utilizes the targeted 30 tonnes of CO2 per day, supplying it to nearby greenhouses.
Ongoing monitoring, data collection, and optimization of the system.
2022:
The initial demonstration phase concludes, but the capture unit remains operational for further research and development.
