In addition, CarbFix is already showing results. Matter observed that the acidic solution is being neutralized underground, indicating that the rock-forming reaction is taking place. "If it's mineralized within a human lifetime, then we know we are on a successful pathway," he said. As the technology improves and the costs come down, Matter thinks sequestering carbon dioxide in basalt could become a viable strategy for controlling greenhouse gas emissions.
Proof of permanent storage could ease some of carbon capture's commercial problems. One of them is obtaining insurance coverage, because insurers are concerned about the long-term financial risks of storing carbon dioxide in a gaseous or liquid form underground, which include the possibility of leakage.
