New partnership looking into ocean-based carbon capture in commercial shipping

Naval architecture and marine engineering company AURELIA Design and climate-tech company CALCAREA have joined forces to bring ocean-based carbon capture to commercial shipping.

The collaboration seeks to combine AURELIA’s expertise in green ship design and e-systems integration with CALCAREA’s carbon removal process.

The partnership will focus on CALCAREA’s limestone weathering technology, a system that accelerates a natural process where CO2 reacts with limestone and seawater, transforming it into stable bicarbonates stored in the ocean.

The two companies intend to develop a next-generation bulk carrier, fully integrating the CALCAREA reactor and supporting systems into the vessel architecture. AURELIA will lead the naval architecture, system integration, and class compliance engineering, ensuring the technology can operate efficiently and safely in real ship conditions without affecting cargo capacity.

The study will be conducted to analyze seawater flow dynamics, intake and discharge configurations, and hull shape, aiming to maintain performance while minimizing fuel impact. The design will serve as the foundation for a scalable and class-ready newbuild platform, the partners said.

As revealed, the Phase 0 feasibility and concept study is now underway and will
