About us

Cestore was founded by Johanna Hultén and Johan Levander with a clear vision: to make the ocean’s natural carbon cycle accessible as an industrial climate solution.

Johanna, with deep experience from the energy sector and climate tech, is the innovator behind the core technology. Johan brings two decades of industrial experience in developing and managing projects within the industry. 

Our solution is based on one of nature’s most powerful mechanisms for carbon storage—the ocean’s buffering system. We have developed a process that enables industry to permanently convert its CO₂ emissions into stable, naturally occurring salts, directly on site. 

A technology that avoids the heavy infrastructure, high costs and complexity that characterise today’s CCS value chain — enabling scalable, local and truly durable carbon removal.  

We believe that the future climate infrastructure must be scalable, robust and close—close both geographically and in time. That is why we are building a solution that can be deployed directly at industrial point sources in the near future.
