I must be hearing about a new renewables technology almost every week at the moment. Tonight I learnt about a very surprising one… Geopressure. Apparently we have the potential resource in this country to generate a coal power station’s worth of energy from the naturally occurring geological pressure which builds up in gas pipes across the country. I’d never even heard of this pressure, which apparently has to be let off at various sites, but this article in the IET engineering magazine says that this pressure can be harnessed to generate power. The government has agreed and is going to provide support for such projects. It could save the equivalent carbon emissions of the NHS.
