India is blessed with an extraordinary geological feature that may provide a natural solution to the problem of climate change, according to some geologists. India has indeed an additional option, some geologists believe. This consists of capturing the CO2 coming out of coal-fired power plants and injecting it below the Deccan Traps for permanent storage. Deccan Traps – a thick pile of solidified lava from volcanic eruptions 65 million years ago – occupies about a third of peninsular India and is the world’s largest continental flood-basalt province outside Siberia. The trap cover varies in thickness from a few hundred to a few thousand metres and, below this, lie thick sedimentary rocks. The idea is to pump the CO2 through the porous sedimentary rocks and use the basalt layer above as a “cap” to stop the gas escaping.
