San Diego-based company Redoxblox has raised an impressive $40.7 million in a Series A funding round to advance their pioneering high-temperature metal oxide battery technology. This technology aims at long-duration, grid-scale energy storage and industrial decarbonization. Using relatively inexpensive materials, the thermochemical storage technology developed by Redoxblox can store energy at high densities with minimal energy loss, offering a more efficient alternative to conventional lithium-ion batteries. The company’s innovative batteries are designed to release energy as heat at temperatures reaching up to 1,500 degrees Celsius, meeting the demands of industrial uses such as cement production.
Groundbreaking Thermochemical Storage Technology
Advantages and Capabilities of Redoxblox Modules
Characterized by their stability and longevity, Redoxblox modules utilize non-toxic, non-flammable, and recyclable materials. These 20-MWh capacity batteries can fully charge within a span of two to four hours, achieving up to 95% round-trip efficiency, which measures the useful energy output against the total energy input. During the charging phase, metal oxide pellets housed within the modules are heated to release oxygen and store heat chemically. When discharging, the reverse process occurs, where oxygen recombines with the metal oxide to release heat that can be utilized directly or to generate electricity via a gas turbine.
Redoxblox’s Chief Technical Officer and co-founder, Jörg Petrasch, emphasized the company’s goal to present their technology as a viable zero-carbon alternative to natural gas. This ambitious objective aligns with global efforts toward decarbonization, especially in industrial sectors that require significant heat. By addressing the persistent challenges of efficiency, cost, and reliability, Redoxblox aims to facilitate the transition away from fossil fuels, contributing significantly to the sustainability of industrial processes and renewable energy storage systems.
Funding and Demonstration Projects
Redoxblox’s remarkable funding journey includes substantial support from premier institutions. The California Energy Commission contributed $8.9 million, while the U.S. Department of Energy provided $6.7 million. These funds are allocated towards two primary demonstration projects designed to validate the efficacy and versatility of Redoxblox’s batteries. The first project is a collaboration with the University of California at San Diego and the Electric Power Research Institute (EPRI), aimed at confirming the long-duration storage capabilities of the technology. The second demonstration, conducted in partnership with Dow and EPRI, focuses on decarbonizing industrial steam at a Dow facility in West Virginia.
Participants in the recent funding round, including Imperative Ventures, New System Ventures, Breakthrough Energy Ventures, Khosla Ventures, and the Michigan State University Research Foundation, have not only enhanced Redoxblox’s financial backing but also bolstered its credibility within the industry. This diverse array of supporters underscores the widespread confidence in Redoxblox’s potential to revolutionize energy storage and industrial heating applications.
Paving the Way for a Sustainable Future
Strategic Positioning and Industry Impact
With its thermochemical battery technology, Redoxblox positions itself as a transformative force in the transition away from fossil fuels. By addressing key issues such as efficiency, cost, and reliability, the company seeks to make renewable energy storage and industrial heating systems more sustainable. The innovative approach of Redoxblox can revolutionize both the energy and industrial sectors, offering a cleaner, more efficient alternative to traditional methods and paving the way for a zero-carbon future.
The wide-ranging implications of Redoxblox’s technology extend beyond just energy storage. By enabling high-temperature industrial processes to become more sustainable, the technology directly contributes to reducing the carbon footprint of energy-intensive industries. As industries worldwide grapple with the challenges of reducing emissions and meeting stringent environmental regulations, Redoxblox’s batteries provide a pragmatic and scalable solution.
