SiBox is the complete thermal energy storage system – designed to be retrofitted to heavy industry processes to provide clean heat. 


Our proprietary silicon-based storage technology – SiBrick™ – is installed within SiBox to safely and efficiently store renewable electricity as latent heat.


SiBox is a viable replacement for fossil fuels and can provide industry with reliable, decarbonised, ultra-high-temperature heat 24/7.


Process heat costs Australian industry $8 billion annually, so this technology is a game-changer for industries (including the minerals, cement and alumina industries) seeking to replace fossil fuels with an affordable opportunity to access clean heat.

How does it work?

SiBox absorbs low-cost renewable energy from the grid and stores it as heat in our proprietary silicon storage media, SiBrick. It provides high-temperature air output, up to 1000°C, coupled to the process via an energy recovery system.

The benefits

Silicon’s very high melting point (1414° Celsius) and high energy density means it can hold much more energy than other phase change materials and supplies consistent heat and electricity in the proportions required by consumers.

Silicon’s high energy density also means this solution has a smaller foot-print, compared to alternatives, and does not require a constant power input – making it a cost-effective solution to replace fossil fuels.

How SiBox can be applied

1414 Degrees’ silicon storage media is the most advanced technology to replace fossil fuels at temperatures above 800 degrees. There are various opportunities for its application across the minerals processing and manufacturing industries –including the cement, alumina and iron and steel sectors.

Our silicon storage media could be used as:

  • part of a scaled-up SiBox Demonstration Module, generating hot gas
  • the lining of a novel reactor
  • heat recovery in a regenerative furnace.

How SiBox was developed

SiBox is the culmination of over a decade of research and development by 1414 Degrees in silicon based latent heat thermal energy storage.

Work to develop the SiBox Demonstration Module was undertaken in a dedicated workshop for SiBox research and development, backed by strategic industry collaborators – particularly Woodside Energy Technologies – and university collaborators who provided specialised skills and experience.

    Why does industry need our SiBrick?

    About 45% of the world’s energy-related emissions come from heat and Australian industry alone spends $8 billion annually on process heat.

    High temperature industrial heat has no commercial options to stop the use of fossil fuels – but global climate ambitions demand a solution.

    1414 Degrees’ technology is the most advanced storage technology able to replace fossil fuels at temperatures over 800°C. This technology will make energy more reliable, affordable and environmentally friendly by harnessing silicon to provide very high temperature storage and regeneration.
