Scientists are claiming to have discovered a new metal that can be utilised by metal press works to create the next generation of solar panels. Why is it so special? Because this new metal can apparently absorb sunlight and store it as heat energy until such a time as it is needed for use.

Researchers at the Massachusetts Institute of Technology believe the metal could be used as a rechargeable heat battery to help heat a home.

The metal is called fulvalene diruthenium and when a molecule of the metal absorbs sunlight it changes into a semi-stable yet safe state and scientists believe they will be able to use this in the energy solutions of the future.

When the heat is released, fuel made from fulvalene diruthenium is capable of becoming as hot as 200C. Heat is released via the use of a catalyst, with the metal staying in its semi-stable state until the catalyst is present.
