11.4.4.1: Molten Silicon

No headers. In Australia, a startup company CCT Energy Storage has created an unusual "thermal battery" using not molten salt, but molten silicon. This is a remarkable achievement, given that the melting point of silicon is as high as 1410 degrees Celsius (or 1683 K), almost twice as high as the highest temperature used in the molten salt technology.

6 FAQs about [Molten Silicon Energy Storage]

Can solar energy be stored in molten silicon?

Researchers from Solar Energy Institute at UPM are developing a new energy storage system in which the entry energy, either from solar energy or surplus electricity from a renewable power generation, is stored in the form of heat in molten silicon at very high temperature, around 1400 °C.

Could molten silicon power the grid?

“In theory, this is the linchpin to enabling renewable energy to power the entire grid.” MIT engineers have designed a system that would store renewable energy in the form of molten, white-hot silicon, and could potentially deliver that energy to the grid on demand.

What is molten silicon?

A novel system has been created that allows the storage energy in molten silicon which is the most abundant element in Earth's crust.

What is thermal energy grid storage – multi-junction photovoltaics?

The new MIT storage concept taps renewable energy to produce heat, which is then stored as white-hot molten silicon. The U.S. researchers have dubbed the technology Thermal Energy Grid Storage – Multi-Junction Photovoltaics. The technology uses two large 10-meter wide graphite tanks, which are heavily insulated and filled with liquid silicon.

Could liquid silicon be a renewable storage system?

They initially proposed a liquid metal and eventually settled on silicon — the most abundant metal on Earth, which can withstand incredibly high temperatures of over 4,000 degrees Fahrenheit. Last year, the team developed a pump that could withstand such blistering heat, and could conceivably pump liquid silicon through a renewable storage system.

What are the properties of silicon?

Silicon has unique properties that confer the ability to store more than 1 MWh of energy in a cubic meter, ten times more than using salts. Molten silicon is thermally isolated from its environment until such energy is demanded, when this occurs, the heat stored is converted into electricity.
