Calcarea and Aurelia Design partner to develop new carbon capture tech

California-based climate tech company Calcarea has partnered with naval architecture firm Aurelia Design to build a bulk carrier equipped with Calcarea’s carbon capture system.

The system employs limestone weathering technology, which accelerates a natural chemical reaction where carbon dioxide (CO2) interacts with limestone and seawater, converting it into stable bicarbonates that can be safely stored in the ocean.

This method provides a permanent and low-infrastructure solution for capturing and storing CO2 — particularly well-suited for the maritime sector, where seawater is abundant and continuously circulated.

As part of the collaboration, Aurelia Design will oversee the naval architecture aspects, ensuring the system functions efficiently and safely aboard real ships without reducing cargo capacity.

“We see shipping as one of the most natural environments for large-scale carbon removal… ships operate surrounded by seawater — the very medium our process uses. Partnering with Aurelia allows us to bridge science and engineering, and turn our technology into a deployable maritime system,” Calcarea’s chief technology officer, Pierre Forin, said.
