E.ON and University of Nottingham combine to develop 'super batteries'

The University of Nottingham is working with E.ON to develop a next generation 'super battery' which will enable households and businesses to benefit from clean, cheap and powerful energy storage. 

The contract with the University to develop the new energy storage device (known as a supercapattery) is one of three research projects amounting to a total of £1 million that E.ON is sponsoring, which aim to improve energy storage technologies and energy efficiencies for businesses and households.   

The largest of the three projects that the University is undertaking with E.ON is the development of the supercapattery technology. A supercapattery combines the fast charge and discharge qualities of a supercapacitor, with the energy storage benefits of a battery, and does so at a low price. 

A variety of applications

Made from carbon nanotubes chemically engineered with advanced battery materials, the supercapattery has a variety of applications ranging from powering portable electronics such as notebook computers, to using arrays of supercapatteries which would offer large scale energy storage solutions for power companies.

Supercapatteries can also be brought into action at very short notice to provide the additional power required, and the crucial stability needed by the national grid, in the event of a national power surge. 

Professor George Chen, who is leading on the supercapattery project for the University, said: "Typically, an extra five per cent of the power of the national grid is standing by in reserve in case of a surge, for example when everyone puts their kettle on after a football match has finished. It is very expensive to do this, and supercapatteries offer a more cost effective and environmentally friendly alternative."

Saving energy in the home

The second project of the three sees an investigation into the alternative use of batteries which are currently used in electric and hybrid cars as potential energy storage devices for homes. The project aims to develop an understanding of the potential benefits of batteries where households such as those which use solar power for instance, can harvest their own energy for later consumption, or else sell it on to the national grid at peak periods.
  
The final project with E.ON will focus on the study of various energy saving retrofits to the E.ON Research House, based at University Park, to help to gain a better understanding of how to save energy and reduce carbon emissions in the home. The E.ON Research House is a typical 1930s semi-detached house which will be incrementally upgraded to improve aspects such as insulation, glazing and energy storage. The project will also test out innovative new technologies that aren't commercially available, which could become an important part of future retrofit solutions in homes.
