Featured by the BBC, the technology dissolves captured carbon dioxide in water before injecting it deep underground into volcanic basalt rock, where natural chemical reactions transform it into stable minerals. This offers a way to store carbon permanently rather than relying on conventional underground gas storage.
Key findings:
- The process dissolves CO₂ in water before injecting it into porous basalt formations, reducing the need for energy intensive gas separation.
- Chemical reactions between the dissolved CO₂ and volcanic rock transform more than 95% of injected carbon into stable minerals within two years.
- The technology has demonstrated the potential for long term carbon storage, with ongoing efforts to expand its application and improve the economic viability of large scale deployment.
CarbFix2 demonstrates how natural geological processes could play a role in developing more effective carbon capture and storage solutions.
