1414 Degrees

Clean and scalable thermal energy storage offering combined heat and power solutions.

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.

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


On the 12th of December 2019, 1414 Degrees completed the purchase of SolarReserve Australia II Pty Ltd, which has since been renamed SiliconAurora Pty Ltd.  

SiliconAurora owns the advanced Aurora Solar Energy Project (“Aurora Project”) near Port Augusta in South Australia.

The Aurora Project has SA Government development approval for a 70 MW solar PV farm and 150 MW of generation from a concentrated solar thermal plant (CST). 1414 Degrees proposes to use the site to pilot its world-leading TESS-GRID technology, alongside the PV generation.

Positive levelised cost of storage (LCOS) results

Our commercial review shows the TESS will be competitive with other storage technologies when compared with the levelised costs of storage (LCOS) analysis, based on the respected Lazard methodology.

The pilot installations have shown that we can now build a TESS at a significantly reduced cost (see chart to right). Furthermore the projections for future systems will decline steeply. The future LCOS of the TESS will be comparable with long duration pumped hydro.

What is 1414 Degrees?

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

1414 Degrees’ patented Thermal Energy Storage System (TESS) takes in electricity or biogas, stores it as heat and discharges both heat and electricity in the proportions required. The TESS 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 1414 Degrees. It is unique in its combination of versatility, scalability and sustainability.
