Icelandic startup turns CO2 into rocks

A project by startup Carbfix aims to turn carbon dioxide into rocks, causing greenhouse gas to be stored rather than going into the atmosphere and retaining heat.

The Reykjavik-based company on iceland's coast wants to capture and dissolve CO2 in the water and then inject it into the ground, where it will turn to stone in up to two years. According to Carbfix CEO Edda Sif Pind Aradottir, the technology is cheap and environmentally friendly. "Basically, we're just doing what nature has been doing for millions of years, so we're helping nature help itself."

The procedure can happen in two ways: through "carbon capture", where gas is captured from chimneys of factories and power plants before escaping into the atmosphere. The other way is by "carbon removal", which removes CO2 directly from the air.

Carbon capture and storage has attracted high-profile investors such as Microsoft co-founder Bill Gates and Tesla CEO Elon Musk. Both executives, along with several other companies, seek environmentally friendly social and environmental actions to avoid the effects of global warming.
