Will shale gas come to Scotland?

Oil and gas experts have been meeting in Edinburgh to debate whether Scotland could benefit from a shale gas revolution.

Ineos-owned Grangemouth looks set to become the first chemical plant in the UK to receive shale gas from the United States.

A British geological survey will look at the potential of fracking for shale gas in the central lowlands of Scotland, but environmentalists are concerned.

BBC Scotland's Catriona Renton reports from the proposed site of the new ethane tank at Grangemouth.
