A team of researchers have outlined a method that allows atmospheric carbon turns into solid rock in just a few months time.
In a study published in Science, the outlined method involves mixing carbon dioxide and hydrogen sulfide with water, injecting it into volcanic basalt underneath the power plant.
The project called CarbFix was done at the Hellisheidi power plant, the world’s largest geothermal facility. When this carbon dioxide produced by the facility and the water meets the basalt, forms a white chalky solid.
Geoengineer and lead researcher Juerg Matter said, “Our results show that between 95 and 98 percent of the injected CO2 was mineralised over the period of fewer than two years, which is amazingly fast.”
The CarbFix project’s primary goal is to imitate the natural storage process of carbon dioxide that already observed in basaltic rocks in Icelandic geothermal fields. It’s implications to fight against global warming may be considerable since the basaltic bedrock susceptive of carbon dioxide injections are widely found in the planet.
