The British government is launching a competition worth £1 billion to encourage companies to develop industrial-scale carbon capture and storage technologies.
These are ways of trapping and then burying carbon dioxide released by fossil-fuelled power stations, the BBC reports.
Pilot schemes have shown that it would be possible to pipe carbon dioxide into long-term storage in the rocks beneath the North Sea, significantly cutting Britain's greenhouse gas emissions.
But the stumbling block has been to do it affordably and on a large scale.
