1414 Degrees

A highly efficient, clean, scalable and sustainable thermal energy storage system (TESS), unlike any other energy storage system in the world.

1414 Degrees technology delivers an output of heat as well as electric power.

Energy is sourced from renewables or the grid, and is stored as latent heat at constant temperature.  The energy is then dispatched on demand.

This breakthrough technology is set to disrupt energy storage globally because it provides energy in the form most used in the world – heat.

What is 1414 Degrees?


a patented thermal energy storage system (TESS) storing energy as latent heat in molten silicon 



sizing of systems from 10 to 1000’s of megawatt hours for grid, off-grid and co-generation sites 


 benign environmental impact and carbon footprint reduction


 low maintenance, low cost and low impact compared to lithium-ion batteries



 silicon stores energy at 1414°C providing maximum efficiency of energy output


the use of abundantly available silicon ensures its sustainability and its affordability


Geographically unlimited

TESS can be located in any climate, in any location. It is suitable for grid, off-grid and co-generation installations


 wide range of uses in district heating, industrial complexes and shopping centres as well as grids


Scalable technology

The fly-through animation is an artistic impression that demonstrates the scalability of the 1414 Degrees technology to 1GWh and beyond. Energy can be sourced from renewables or the grid and the clean heat and electricity delivered to industry or back to the grid when required.

1414 Degrees is developing joint ventures to commercialise its technology, incorporating generation, thermal storage and industry with heat energy requirements.
