The world’s first coal-fired power plant with carbon capture and storage has been opened in Saskatchewan, Canada.

The 110 megawatt plant is being hailed by the coal industry as proof that it is possible to go on burning fossil fuels while avoiding dangerous global warming.

After being pumped into underground storage, the CO2 is being sold to the Canovus oil company which is using it to to prime a nearby oil field.

The value of the demonstration is being seriously questioned by environmentalists because its economic viability depends on using the CO2 to increase oil production and it is still more expensive than renewable sources of energy.
