Just Add Water: New Salt Battery Could Help Spell the End of Fossil Fuels

This groundbreaking new project in Germany is testing the use of salt as an ingredient for a fossil fuel-free future.

The Reuter power plant in Berlin recently launched a new system of technology that is using calcium oxide, also known as quicklime, to store heat for long periods of time.
