We are pleased to announce the successful completion of our SiBox Development Agreement with Woodside Energy Technologies, achieving all program milestones and retaining full ownership of our breakthrough thermal energy storage technology.
The completion of this program marks a significant milestone for 1414 Degrees, with the SiBox thermal energy storage technology demonstrating capabilities that firmly position it as a leading solution for industrial decarbonisation.
Proven performance
Across the program, SiBox consistently exceeded performance expectations. The system:
-
Delivered very stable heat output with variations of just ±2°C
-
Operated at internal temperatures over 1000°C, and
-
Sustained long-duration storage and dispatch cycles while maintaining reliable performance across multiple operating sequences.
These results validate SiBox as one of the few solutions worldwide capable of delivering both long-duration storage and high-temperature, dispatchable heat — critical requirements for industrial customers seeking to replace fossil fuels.
Strategic commercial outcome
Following the successful demonstration, Woodside has retained a non-exclusive licence, while 1414 Degrees maintains full ownership of the technology and all associated value.
This outcome preserves complete ownership of the intellectual property and reinforces the commercial potential of SiBox. The program was funded by more than $3 million from Woodside, significantly reducing costs for 1414 Degrees while providing valuable external validation and technical oversight.
Market positioning and Heat-as-a-Service
With full technology ownership retained, 1414 Degrees is well positioned and actively pursuing commercial partnerships and customer relationships. Our commercialisation strategy is focused on implementing a Heat-as-a-Service (HaaS) business model.
By overlaying an energy management system on our energy storage technology, we manage intermittent electricity and transform it into a steady, controllable supply of heat for industrial processes. This requires specialised skills and sophisticated algorithms — capabilities that we provide so clients don’t have to. The result is a simple, seamless solution that removes the complications of juggling complex energy supplies, allowing industry to adopt clean heat easily and focus their expertise on doing what they do best: producing the goods and materials that drive their business.
For industrial customers, HaaS provides predictable, low-cost renewable heat without the complexity of managing energy markets. Early modelling indicates that SiBox can deliver industrial heat at costs that are competitive with, and in many cases lower than, gas — while also providing flexibility to the grid. This combination positions the technology as both technically validated and commercially attractive.
1414 Degrees’ Chairman Dr Moriarty noted: “Our focus now is on using the energy storage technology to enable a profitable Heat-as-a-Service business model, turning the increasingly variable electricity market price into competitive advantage.”
Broader technology portfolio
Beyond SiBox, we continue to advance our diversified technology portfolio, including:
-
Aurora Energy Precinct – progressing grid connection and development activities, and
-
SiPHyR turquoise hydrogen program – supported by $1 million in funding from Woodside.
This portfolio approach creates multiple growth pathways in the expanding clean-energy sector.
Positioned for global opportunity
The successful completion of the SiBox development program comes at a time when long-duration energy storage is attracting significant global investment and policy support. With proven capability to deliver both sustained storage and high-temperature heat, SiBox is uniquely placed to compete in this growing market.
