Cestore has officially moved into Granryd Laboratory at KTH — an important milestone in the development of our new process for permanent carbon storage.
In September 2024, Cestore established its R&D base at Granryd Lab within KTH’s Division of Applied Thermodynamics and Refrigeration. Granryd Lab is a state-of-the-art research environment that combines experimental test platforms with modelling, simulation and system analysis, and serves as a hub where industry and academia jointly develop sustainable energy systems.
The move marks the starting point for building Cestore’s first prototype and test platform, where our electrochemical CO₂-conversion process will be developed and validated. At Granryd Lab, we gain access to:
- Advanced laboratory infrastructure for energy and process systems
- Specialised experimental setups, rigs and instrumentation
- A fully equipped mechanical workshop for constructing prototype components
- Deep expertise in thermodynamics, heat transfer and system integration
- An innovation-driven environment designed for industrial collaboration
“Establishing our development environment at Granryd Lab is a major opportunity for Cestore. The lab provides exactly the advanced equipment, expertise and flexibility needed to build and optimise our first prototype. It gives us the right conditions to accelerate our path toward a verified Proof of Concept and onward to pilot-scale testing,”
– Johanna Hultén, Founder & CEO, Cestore
At Granryd Lab, Cestore will construct and test the core subsystems of the process, measure mass and energy balances, and verify the conversion of CO₂ into stable inorganic carbonates. This work is a key part of our roadmap toward TRL3–6 and enables close collaboration with researchers and engineers at KTH, as well as third-party validation through RISE.
Our establishment at Granryd Lab is a significant step forward in our long-term development journey — bringing us closer to offering industry a novel, permanent and scalable solution for carbon storage.
