Scottish island of Gigha is an experiment worth 2.5 million pounds designed to solve a major technological problem: storing energy efficiently generated by windmills.
The project will involve the construction of giant batteries containing 75,000 liters of sulfuric acid mixed with vanadium pentoxide, is for the power generated by wind turbines on the island, to be stored for later use, writes The Guardian.
Currently, while the Gigha turbines are operating, their power is used to supply households on the island, and the excess is sent by cable to the mains electricity.
When winds are weak and do not generate energy turbines of Gigha, the network is providing power to the island. However, it has an upper limit of power .
As a result, much of the excess energy of the island can not be transmitted to dry and is wasted. Battery Projec, supported by the Department of Energy and Climate Change, aims to find a solution to this problem.
" It is not easy to store electricity on a large scale," said John Samuel of REDT, the company was awarded the contract battery. " Standard lead- acid batteries lose generally their job relatively quickly. The batteries that work do not experience this problem. "
Samuel says the batteries could store enough power to provide the island with 100 kW of power for 12 hours, when winds are low. " The important thing is that the battery can be used continuously without the need to change them," he added.
