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. 

1414 Degrees (ASX:14D) makes large scale energy storage for networks and industries. Its combined heat and power (CHP) solutions fill a critical gap in energy storage.

SiBox, our Thermal Energy Storage technology, is set to reduce energy costs by increasing the efficiency of renewable generation and stabilising grid supply. 1414 Degrees technology will make energy more reliable, affordable and environmentally friendly by harnessing silicon to provide very high temperature storage and regeneration.  

Silicon’s very high melting point, 1414° Celsius,  and high energy density  means it can hold much more energy than other phase change materials. It delivers maximum energy efficiency. 

SiBox stores renewable energy and supplies both heat and electricity in the proportions required by consumers. It is unique in its combination of low cost, flexibility of location, scalability, and sustainability. 

It transforms intermittent renewable electricity by providing reliability and stability to grids identical to that of a coal or gas fired power station. 

The result is low cost and clean storage of energy providing a stable supply of heat for consumers and electricity to the grid – a critical requirement for increasing renewable generation.
