1414 Degrees

Clean and scalable thermal energy storage

The energy industry is in transition and storage is integral to keeping the lights on in a renewable energy future.

1414 Degrees’ large scale storage solutions will solve the threats of uncertain supply and high prices by addressing both heat and electrical energy needs for a clean, sustainable future.

Our technology offers a unique solution delivering both heat and electrical energy, to decarbonise the energy industry.

What is 1414 Degrees?

1414 Degrees technology will stabilise renewables to make clean energy available to all, at all times.

1414 Degrees’ thermal energy storage technology, SiBox™, takes in electricity or biogas, stores it as heat and discharges both heat and electricity in the proportions required. SiBox provides an alternative to gas, coal or electricity for process heat, enabling low cost carbon reduction using renewable energy sources.

Our technology is the first of its kind – no other solution will deliver heat and electrical energy at the scale and low cost of SiBox. It is unique in its combination of versatility, scalability and sustainability.



a patented thermal energy storage system 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

It 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


Our Vision

Access to energy should be as simple as flicking a switch. Our goal is to make clean, affordable energy available to all, at all times.

Distributed within grids with high renewable penetration, 1414 Degrees’ solutions will stabilise networks while providing lower cost energy for industry.

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