Rio Tinto Eyes Giant Hot-Brick Battery to Cut Fossil Fuel Use in Mining

Rio Tinto Evaluates Giant Hot-Brick Battery for Industrial Heat Decarbonization

Rio Tinto is evaluating a giant hot-brick battery storage scheme to displace fossil fuel use and supply clean heat for high-temperature mining processes. The technology falls under industrial thermal energy storage, using electricity to heat high-temperature materials and store thermal energy for on-demand release, replacing coal or gas.

Key Technical Elements

• Hot-brick thermal storage: Electricity heats high-temperature materials that store thermal energy for later release.
• Fossil fuel displacement: Designed to replace coal or gas in high-temperature industrial processes.
• On-demand heat release: Stored thermal energy is dispatched when process heat is required.
• Industrial scale: The scheme targets large-scale mining operations with continuous heat demand.

Impact on B2B Stakeholders

This means mining and heavy-industry decarbonization is driving long-duration storage and industrial electrification projects. Suppliers of electric heating, storage materials, power electronics, and system integration should monitor demonstration opportunities emerging from such evaluations. Robust cell and pack engineering expertise is relevant as industrial storage systems scale toward commercial deployment.

Market Context

Industrial thermal energy storage is gaining attention as a pathway to decarbonize high-temperature processes that are difficult to electrify directly. According to Electrek, the hot-brick battery scheme is being evaluated to displace fossil fuel use in Rio Tinto operations.
