Currently, heat production accounts for 49% of all primary energy consumed in the UK, far more than in the production of electricity or that used in the transport sector. The report, based on new research undertaken by the University of Southampton sustainability energy research group, states that the use of Combined Heat and Power (CHP) technology would allow the capture and re-use of waste heat produced in the electricity generation process, cutting energy consumption and carbon emissions.
A member of IC's Energy Panel, Dr Keith Tovey, said: "The truth is, that if half of the heat lost during electricity production could be captured it would meet 25% of the UK's heat demand, dramatically reducing energy consumption, cutting costs and carbon emissions. Whilst this level of capture and re-use is not possible under the current organisation of the sector - and there are technical difficulties that need to be addressed - there are immediate opportunities for recycling and re-use, particularly at a local level that could have a marked impact.

"What we need to do is look closely at introducing district heating networks in areas surrounding viable existing power stations in the UK and ensure we assess potential heat capture possibilities for any new facilities.
"In the longer term we need to consider the potentially huge benefits that decentralised CHP could bring to the UK. With the current generation of thermal power stations coming to the end of their lifespan, there is a real opportunity to vastly improve the efficiency of our energy sector and drastically lower its carbon footprint."
The report explains that heat recovery from existing centralised power stations could meet 5% of our current heating demand by 2020. This would largely be achieved through the introduction of CHP and district heating networks at specific locations, where there is a significant population within a 10km radius of a viable power station, such as those at Drax, Ferrybridge and Eggborough.
