(WO) — Block Power plc mentioned outcomes from its Section 1 carbon seize and storage (CCS) pilot in Georgia affirm speedy and everlasting mineralization of injected carbon dioxide, marking a technical milestone for the venture.
Put up-injection sampling and third-party laboratory evaluation confirmed that between 70% and 100% of the CO₂ injected in August 2025 has mineralized throughout the reservoir. The corporate mentioned the CO₂ precipitated into stable carbonate minerals in situ, offering proof of everlasting storage.
As a part of the pilot, 13.6 tons of CO₂ and a tracer compound have been injected into the Center Eocene reservoir via the PAT-49 effectively on the Patardzeuli subject. 4 related monitoring wells have been sampled through the monitoring part, with formation water and floor gasoline measurements collected in step with worldwide carbon and mineralization requirements.
No gaseous CO₂ was detected at floor, and formation water samples have been independently analyzed by a laboratory in Azerbaijan. OPC, Block’s technical advisor, concluded that geochemical evaluation of the samples demonstrated 70% to 100% mineralization inside three months of injection.
Tracer concentrations elevated within the monitoring wells as anticipated, whereas dissolved CO₂ ranges remained low, supporting the conclusion that the injected CO₂ had transformed into stable minerals throughout the reservoir.
Block mentioned the pilot materially de-risks the venture and offers a technical basis for field-wide scale-up and commercialization. Early assessments estimate the Center Eocene reservoir may retailer as much as 151.5 million metric tons of CO₂ via mineralization beneath a mid-case state of affairs.
Paul Haywood, chief govt officer of Block Power, mentioned the outcomes validate the underlying storage mechanism.
“These outcomes are a significant technical milestone for Block. Put up-injection sampling and third-party laboratory evaluation has confirmed speedy and everlasting mineralization of CO2 within the reservoir, materially de-risking the venture and enabling us to take the following steps towards growth and commercialization,” Haywood mentioned.
He added that the venture advantages from present infrastructure and proximity to industrial CO₂ sources.
“Mineralization offers a basically totally different and higher-integrity type of storage as in contrast with standard CCS and delivers everlasting storage with out the reliance on long-term trapping mechanisms,” Haywood mentioned.
Block mentioned Section 2 plans embody refining storage capability estimates, advancing impartial certification of everlasting storage, and evaluating commercialization pathways, together with third-party storage and integration alternatives with three way partnership companion Rustavi Azot, a subsidiary of Indorama Company.
Prakash Kejriwal, group director of Indorama Company, mentioned the pilot helps continued growth.
“The interim outcomes from the pilot performed by Block’s workforce are very encouraging and supply a powerful basis for Section 2 actions,” Kejriwal mentioned.
