Energy storing material developed

Scientists at Nottingham Trent University say they have developed a new material which could reduce energy consumption by up to 35%.

The "phase change material" has special properties that can store and emit heat and cold.

The technology could allow human organs and vaccines to be transported without the need for a fridge.

Dr Jo Darkwa, head of the research team, said it could help to sustain an energy-efficient environment.

"This research is vital as the building sector alone is responsible for about 50% of the UK's energy use and carbon dioxide emissions, " he said.

Other possible uses for the material include keeping takeaway food warm and preventing circuit boards in televisions and computers from over-heating.

The research was carried out with the help of a £130,000 grant from the Engineering and Physical Sciences Research Council.
