Controversial plans to exploit underground gas in central Scotland could be stymied by problems with the quality of the gas, the Sunday Herald can reveal.

But the Sunday Herald has seen evidence that the calorific value of the gas, which is crucial in determining its price for consumers, is unlikely to be high enough for the National Grid.

Dart declined to directly answer questions about calorific value, though it insisted that its gas would be saleable. Critics, however, claimed that the gas-quality issues could be the "final straw" for the Falkirk development.
