1414 Degrees

1414 Degrees Limited is an Australian public company focused on developing and commercializing its silicon-based thermal energy storage technology to provide high-temperature heat for industrial clients. Pioneering in this field since 2008, the company was initially known as Latent Heat Storage Pty Ltd before evolving into 1414 Degrees Pty Ltd in 2016, a name reflecting the melting point of silicon (1414°C). The company listed on the Australian Stock Exchange (ASX) in 2018, a significant milestone overseen by then Executive Chairman Dr. Kevin Moriarty. Dr. Moriarty, with over 40 years in mining and oil development, leveraged his extensive experience in commercializing technologies to guide the company's development of several prototypes, attracting support from entities like Woodside Energy Technologies and the Australian Government.

The core of the company's business is the decarbonization of industrial heat, a sector that accounts for a substantial portion of global energy-related emissions. Its primary clients are in heavy industries such as minerals processing, cement, and alumina, which require reliable, ultra-high-temperature heat and currently have few commercial alternatives to fossil fuels. The business model is expected to center on a capital-light approach, generating revenue through license fees for its systems and royalties from the sale of its proprietary storage media. This strategy involves licensing its SiBox technology to third-party engineering firms and mass-producing its SiBrick media in partnership with established manufacturers.

1414 Degrees' flagship product is the SiBox®, a modular thermal energy storage system that utilizes its proprietary SiBrick® technology. The system works by charging with low-cost renewable electricity, storing the energy as latent heat in solid silicon, and then dispatching it as a continuous stream of hot air at temperatures up to 900°C. A key advantage of using silicon is its high energy density, allowing for a smaller physical footprint compared to other energy storage materials. The successful commissioning of a 1 MWh SiBox demonstration module in 2023 validated the technology's performance, showing it could undergo multiple phase change cycles. Beyond providing process heat, the technology is designed to support grid stability by absorbing surplus renewable energy during low-demand periods. The company is also developing SiPHyR™, a technology that integrates SiBrick storage with a methane pyrolysis reactor to produce low-emission hydrogen and solid carbon.
