Pea sized stones heated to 600?C in large, insulated steel tanks are at the heart of a new innovation project aiming to make a breakthrough in the storage of intermittent wind and solar electricity.
The technology, which stores electrical energy as heat in stones, is called GridScale, and could become a cheap and efficient alternative to storing power from solar and wind in lithium-based batteries. While lithium batteries are only cost-effective for the supply of energy for short periods of up to four hours, a GridScale electricity storage system will cost effectively support electricity supply for longer periods - up to about a week.

Research shows solar photovotaics are already cheaper, more innovative, and more integrated into the world s energy systems than previously expected. Additionaly, system developments already in the pipeline will enhance this upward trend even further. So, assuming politics doesn t prevent it, we might expect global green energy to be available even sooner than previously predicted. .the role of solar photovoltaic installations in future green energy systems ought to be significantly upgraded
A team of researchers led by Aarhus University and including experts from universities and knowledge institutions in the US, Europe, Japan and Australia has published an article in the prestigious scientific journal
