Project leaders<\/strong><\/h2>\n

The project is led by Calcarea Inc.<\/strong>, a company specializing in carbon removal technologies inspired by natural oceanic processes, and Aurelia Design<\/strong>, a naval engineering firm focused on integrating green technologies into next-generation vessels.<\/p>\n

Project description<\/strong><\/h2>\n

The two companies have developed an innovative solution that enables ships to capture atmospheric CO\u2082 while sailing<\/strong> and safely transform it into bicarbonates<\/strong> stored within the marine environment. This regenerative technology\u2014unlike the OCCS systems previously covered at SOM-INN PORT\u2014captures and converts CO\u2082 on board through a reactor<\/strong>, rather than transferring it to another vessel for subsequent storage and treatment.<\/p>\n

The process is based on accelerating a natural ocean reaction. First, the system captures CO\u2082 from the atmosphere. This CO\u2082 is then combined with seawater and crushed limestone, triggering a chemical reaction that converts CO\u2082 into calcium bicarbonate<\/strong>, a stable and safe form of dissolved carbon. The reaction mimics how the oceans naturally store CO\u2082, but accelerates it to ensure faster and more durable carbon fixation.<\/p>\n

Additionally, when the resulting water \u2014with a higher bicarbonate content\u2014 is reintegrated into the ocean, a process of equilibration<\/strong> occurs, prompting the marine environment to absorb more atmospheric CO\u2082 to restore chemical balance. This increases the net carbon-removal effect. The approach aligns with modern Marine Carbon Dioxide Removal (mCDR)<\/em> methods and emerging international standards such as the Direct Ocean Capture and Storage (DOCS)<\/strong> protocol certified by Isometric in 2025.<\/p>\n

As part of their technological development, Calcarea and Aurelia have launched the Phase 0 \u2013 Feasibility and Concept Study<\/strong>, defining design requirements and integrating the chemical system into a bulk carrier<\/strong>. This phase will validate technical feasibility, prepare for Approval in Principle (AiP)<\/strong> by classification societies, and lay the groundwork for a future platform of vessels designed for industrial-scale ocean CO\u2082 capture.<\/p>\n

Project objectives<\/strong><\/h2>\n

The project aims to demonstrate the feasibility of a regenerative ocean-based CO\u2082 capture solution<\/strong>, integrable into next-generation vessels and capable of continuously and safely removing atmospheric carbon. Its implementation seeks to promote a new model of ships that actively contribute to climate-change mitigation and open new pathways for a blue economy based on carbon removal.<\/p>\n
