Cestore has reached an important milestone in the development of its process for permanent carbon dioxide storage. During the spring, the company completed a scaled prototype — approximately 30 times larger than the initial laboratory tests — and the technology has now been independently verified by RISE at TRL 4.
TRL 4 means that the technology has been experimentally demonstrated in a laboratory environment and that its core functions operate in practice, in accordance with the Swedish Energy Agency’s definition.
In connection with the verification, Cestore has also filed two patent applications protecting the core concept behind the electrochemical process that converts CO₂ into stable, water-soluble salts.
“Reaching TRL 4 while simultaneously securing our IP is an important step for Cestore. It gives us a strong technical and strategic platform as we move forward towards the TRL 6 pilot at KTH and continued industrialisation of the technology,” says Johanna Hultén, founder and CEO of Cestore.
With the TRL 4 prototype verified and IP protection in place, Cestore now continues its work towards the next phase: scaling, pilot operation, and preparations for full-scale commercial implementation.
