Energy experts are looking at new ways of using coal reserves to power the nation.

And with almost three-quarters of the region's coal stock remaining undisturbed, scientists think it can be used without spurring climate change.

But the new techniques would not involve re-opening pits.

Instead, new drilling techniques could be used to turn coal into gas below ground. It would then be forced up to and sent to power stations.

Mick Henry, chairman of the Association of North East Councils, is backing such a move.

He has written to the Government asking why it is not offering more support to the new technology.

Mr Henry said: "The profile of the new coal technology has been raised massively, thanks to the work of Professor Paul Younger at Newcastle University, but we won't rest on our laurels.

"Renewable energy is a vital long-term aim, but we need alternatives, like clean coal technology.

"North East England has shaken off its dirty image, and now is the time to do the same for coal.

"Our region already boasts a cluster of companies uniquely placed to take this kind of technology forward."

The "clean coal" process makes the fuel a viable option, because it cuts the environmental impact by piping CO2 into undersea chambers.

This month, the Government snubbed Teesside engineers when it picked their Edinburgh rivals to pilot a £2.3m carbon capture trial.
