CO2 turned into stone in Iceland in climate change breakthrough

Radical new technique promises a cheaper and more secure method of burying CO2 emissions underground instead of storing it as a gasCarbon dioxide has been pumped underground and turned rapidly into stone, demonstrating a radical new way to tackle climate change. The unique project promises a cheaper and more secure way of burying CO2 from fossil fuel burning underground, where it cannot warm the planet. Such carbon capture and storage (CCS) is thought to be essential to halting global warming, but existing projects store the CO2 as a gas and concerns about costs and potential leakage have halted some plans.
