Planet too warm? Bury the CO2

Japan is the latest country to capture carbon dioxide (CO2) from the atmosphere and store it in deep geo logical formations, oceans or as mineral carbonates. There is good reason. The Land of the Rising Sun is the fifth largest emitter of greenhouse gases on the planet. It faces the weighty task of cutting them by 25% by 2020 against 1990 levels.

The Japanese project, at Mikawa power station near Fukuoka Prefecture, is a sign of the increasing credibility of CO2 capture and storage. It is the latest in a worldwide foursome: Sleipner field in the North Sea where the Norwegian oil and gas group Statoily captures CO2 and injects it beneath the seabed; The Weyburn-Midale project in Canada; and, Salah in Algeria.
