Good news! On September 8th Climeworks launched Orca - the world's largest carbon capture and storage plant. When at full capacity the plant will be capable of drawing 4,000 tonnes of carbon dioxide out of the air every year - the equivalent of about 870 cars. So not a huge dent in the overall carbon emissions landscape, but with the relatively small price tag of $10-$15 million dollars to build this could be a viable method of carbon offset for the future.

The plant uses large fans to draw air into it's housed filters where they capture CO2. After the CO2 is captured and concentrated it is then processed by a company called Carbfix. Carbfix is able to mix the CO2 with water and inject the solution over 3000 feet into nearby basalt rock - mineralizing the CO2 in the process. It should take approximately 2 years for the CO2 to turn into stone, thus storing the air-captured gas in the Earth.
