SiBox is the latest innovation in silicon-based thermal energy storage from 1414 Degrees (14D) for medium to long duration applications. It harnesses the exceptional heat capacity of silicon-based storage materials to store energy from intermittent renewable energy sources. Its high temperature air output can be flexibly coupled with many energy recovery systems for use as clean, firm heat for industrial processes or combined heat and power.

SiBox enables intermittent renewable electricity to be stored during hours of excess renewable generation and then dispatched as firmed, high temperature air that can uniquely provide the clean, high temperature heat needed for industrial processes. It is a flexible, scalable and sustainable technology offering a solution to the global need for a decarbonised future.

14D plans to commission a demonstration module of the SiBox technology in 2022 which will accelerate its commercialisation as a competitive clean energy product. The company has previously implemented pilots which have led to the refinement and evolution of its technology.

In 2019 14D made the strategic purchase of the Aurora Energy Project (AEP) located near Port Augusta, South Australia. The focus of the project is to develop a long-term renewable energy project delivering reliable electricity to the region and National Electricity Market. The AEP site will also allow 14D to pilot and demonstrate a large commercial scale version of the SiBox technology.

Hardware unit sales. Heat as a service.

• Thermal storage - using the latent heat properties of molten silicon for high energy storage density and capacity
• Clean hot air - using air as a heat transfer medium removes the need for an inert atmosphere and provides integration flexibility for downstream applications
• System application flexibility - SiBox can be flexibly configured to suit a wide variety of applications including hybrid integration in existing fossil fuel power plants, high temperature processing (e.g. cement, glass, alumina, steel, steam methane reforming) and other heat applications (e.g. thermochemical production of hydrogen)

• Decarbonising industrial heat - reliable clean heat as an alternative to fossil fuels or to supplement existing processes

• Renewable energy shifting - store energy generated from renewable systems at times of excess supply for use during times of peak demand, on the order of days

• Grid balancing - use thermal storage as an additional load or generator on the grid to balance supply and demand
