ACCELERATING THE EARTH’S NATURAL SOLUTIONTO CLIMATE DISRUPTION
Our Team Crafts Scalable, Safe, Permanent and Economical CO2 Storage Solutions through Natural Processes


Our Solution
Calcarea’s technology help reduce and remove carbon emissions by accelerating the Earth’s natural carbon cycle
Based on over a decade of research in leading oceanography and marine engineering laboratories at CalTech and USC, our team has developed a reactor based on “Accelerated Weathering of Limestone”, which can be used to capture emissions from point sources and to safely store carbon captured from the atmosphere.
Calcarea’s technology is smaller, more efficient, and lower cost than today’s best available systems for Marine on-board carbon capture, and it eliminates the dependency on port infrastructure for handling of pure carbon dioxide.
Calcarea’s system takes captured carbon dioxide and converts it into oceanic bicarbonate which is stable, secure, and environmentally benign.”
Our team
About Us
Our scientifically driven team focuses on bringing nature-based solutions to decarbonize the economy.
We are backed-up by world class organizations and leading funds such as Azolla Ventures, the Grantham foundation, Propeller Ventures and CalTech.
We have worked on basic research problems in climate and oceanography for decades before funding Calcarea.
