Introduction to Thermal Batteries and their Potential

Renewables provide 22% of US electricity, but their intermittent nature necessitates energy storage solutions.

Thermal batteries offer a cost-effective way to store excess renewable energy.

They store electricity as heat in materials like graphite or bricks, releasing it on demand.

They can reach temperatures over 3000°F, suitable for powering factories.

Using materials like clay and iron alloy, they avoid supply chain constraints of other technologies.

Challenges and Investments in Thermal Battery Technology

Companies need to scale systems to replace fossil fuel heat, requiring investment and infrastructure upgrades.

Thermal batteries are seen as a solution to decarbonizing heavy industry.

Lithium-ion batteries are too expensive compared to thermal energy systems.

Heat batteries are crucial for decarbonizing industry to reduce greenhouse gas emissions.

Low-cost energy storage can lower production costs and cut CO2 emissions.

Rondo Energy and its Commercial Applications

Rondo Energy built a commercial thermal battery storing solar power for 24/7 high-temperature heat production.

It takes electricity intermittently and delivers steam continuously, meeting industrial needs.

Rondo's approach uses a low-cost, simple energy storage method.

The ability to store energy for months provides grid flexibility.

Thermal batteries offer a low-cost, scalable decarbonization solution for industries like steel, cement, and chemicals.

Rondo uses unrefined materials like clay bricks, storing more energy than lithium-ion at a lower cost.

Rondo plans to scale production to significantly reduce CO2 emissions.

Rondo has announced numerous commercial developments, funding, and partnerships.

These projects span various industries, producing diverse products.

High demand from industries shows the need for this technology.

Partnerships include Eastman Chemical for recycling plant energy storage and H&M for decarbonizing clothing factories.

Antora Energy uses carbon-based blocks and thermophotovoltaic technology.

Antora raised significant funding to commercialize its design and scale production.

Antora's innovation lies in its modular manufacturing process.

Fourth Power uses superheated graphite blocks and thermophotovoltaic cells.

Fourth Power stores energy in graphite blocks and converts heat back to electricity using thermophotovoltaic cells.

Lack of awareness is a major challenge, although it's gaining traction in Europe.

US focus has been on electric vehicles and grid decarbonization, but thermal batteries represent a significant opportunity.

Market education is crucial for faster growth.

Attracting capital and reducing costs are scaling challenges.

Integration with existing systems presents an obstacle, as shown in Eastman Chemical's example.

Despite challenges, thermal batteries' cost advantage positions them as key players in industrial decarbonization.
