Project Summary / Description:

The Green Marine project is part of CCM’s wider portfolio to develop, demonstrate, and scale a revolutionary waste-to-value carbon capture and utilization technology that converts emissions into high-value carbonate products across multiple applications. CCM is actively developing a carbon capture and utilization system within the Horizon Europe–funded Green Marine project, running for 48 months from 1 February 2023. The Green Marine project includes an active land-based engine demonstration in partnership with the Cyprus Marine and Maritime Institute (CMMI), a Centre of Excellence in marine and maritime research. The project captures CO₂ from ship engines and mineralises it using waste desalination brines, producing stable carbonates for ocean deacidification and healthier marine ecosystems.

How Project Affects Greenhouse Gas (GHG) Emissions:

CCM delivers GHG impact through (1) direct CO₂ removal and permanent storage via mineralisation and (2) avoided emissions by displacing conventional carbon-intensive carbonate products (and, in cement use-cases, enabling downstream clinker reduction). Carbon Capture Machine (CCM) is a frontrunner in the green chemistry sector, developing a scalable carbon capture and mineralisation technology designed for manufacturing at scale. Unlike conventional carbon capture systems that rely on toxic reagents or operate at high pressures and temperatures, CCM’s proprietary process applies a low-energy, environmentally benign approach, operating at approximately 70 kWh per tonne of CO₂ captured. Captured CO₂ is permanently converted into stable carbonate materials, delivering durable sequestration while avoiding compression, transport, and geological storage. CCM currently operates three demonstration systems in the US and UK capturing ~20–50 kg CO₂/day each, providing validated, real-world operation beyond the laboratory. Industrial prototypes are planned by Q1 2027, with at least two units operating at 1–3 t CO₂/day, corresponding to ~330–990 t CO₂/year per unit assuming ~330 operating days.

Impact on Underrepresented Groups:

CCM empowers underrepresented groups in the climate movement by embedding inclusion, access, and local value creation into how its technology is developed and deployed. The project focuses on hard-to-abate industrial and maritime sectors that are often located in climate-vulnerable or economically disadvantaged regions, ensuring that climate solutions deliver tangible benefits to communities most affected by industrial emissions.

A key example is CCM’s planned deployment in Bridgeport, Connecticut, aligned with the vision of creating an “innovation corridor” that leverages clean-energy manufacturing as a catalyst for inclusive regional growth. Establishing a CCM facility at this site would support economic revitalisation in a historically underserved community through skilled job creation, workforce development, and local supply chain engagement, while also delivering cleaner air and water.
Women and people from diverse backgrounds are represented across CCM’s leadership and engineering teams. This representation informs decision-making and how projects are designed, implemented, and scaled. CCM also supports early-career scientists and engineers through hands-on R&D, cross-disciplinary collaboration, and exposure to real-world climate infrastructure deployment.
Through international collaborations such as Green Marine, CCM extends these principles globally, combining emissions reduction with skills transfer, community engagement, and equitable participation in the clean energy transition.
