Effectively storing the carbon for many millions of years without the risks and energy costs of pumping CO2 directly underground.<BR/><BR/>Costs are estimated to be less than 20 USD per tonne of CO2 sequestered if done in low wage countries, likely to be much lower than direct CO2 geological sequestration, unless that makes great strides forward. Doing it in these developing countries will be cheap and allows them to gain huge local economic benefits. Using mines close to the large farmland and oceans will minimise transport costs and energy required.Cyril Rhttps://www.blogger.com/profile/17667288494374310919noreply@blogger.com
