San Diego-based Redoxblox has successfully completed an additional $30 million in its Series A funding round, bringing the total raised to $40.7 million. This funding will enable the company to advance its innovative thermochemical energy storage systems (TCES), aimed at facilitating industrial decarbonization and addressing long-duration energy storage needs for the grid. With strong backing from notable investors, Redoxblox is positioned to disrupt traditional energy consumption practices in the industrial sector.

Funding and Strategic Growth

Led by Prelude Ventures, the latest round of funding also saw participation from Imperative Ventures, New System Ventures, Breakthrough Energy Ventures, and Khosla Ventures. The financial boost will be crucial for Redoxblox as it works to commercialize its TCES technology, which offers a cost-effective alternative for energy storage and industrial heating.

Innovative Technology for Decarbonization

Redoxblox’s TCES technology allows for energy to be stored chemically and as heat at high temperatures, enabling continuous or on-demand energy discharge suitable for industrial applications. The system is designed to charge rapidly during low electricity price periods or when surplus renewable energy is available, thus optimizing energy management for industrial users.

Currently, the industrial sector is heavily dependent on fossil fuels for heat, which constitutes approximately 95% of its energy use and contributes to about 30% of global carbon emissions. Redoxblox aims to challenge this reliance by providing an affordable and efficient alternative that uses electricity as a substitute for fossil fuels. The TCES units are expected to offer a conversion efficiency comparable to lithium-ion batteries, alongside higher energy density and direct high-temperature air discharge capabilities.

Leadership Transition

In conjunction with the funding announcement, Redoxblox has appointed Pasquale Romano as its new CEO. Romano, who previously served as the President and CEO of ChargePoint and is a member of the National Infrastructure Advisory Council, is expected to guide the company through its next growth phase, focusing on expanding its market presence in industrial heating and long-duration energy storage.

Romano highlighted the necessity of developing cost-competitive technologies to achieve widespread decarbonization. He stated, "Decarbonization depends on the widespread adoption of affordable alternatives to fossil fuels for industrial heat applications that can adapt to the varying nature of electricity demand and renewable energy generation." His leadership is anticipated to drive innovation and expand Redoxblox's capabilities in these vital sectors.

Significant Partnerships and Projects

The Series A funding follows prior grants awarded to Redoxblox by the California Energy Commission (CEC) and the U.S. Department of Energy (DOE). The CEC selected Redoxblox for a project aimed at demonstrating the ability to provide 24-hour electricity storage capacity in collaboration with UC San Diego and the Electric Power Research Institute (EPRI). Furthermore, the DOE has partnered with Redoxblox for an industrial-scale thermochemical energy storage project with Dow Chemical, focusing on decarbonizing steam production at Dow’s facility in West Virginia. These initiatives signify crucial progress in the large-scale decarbonization of industrial heat and energy storage.

Advantages of Redoxblox Technology

Redoxblox’s TCES technology presents several advantages over traditional energy storage systems. The storage modules are constructed from stable, long-lasting, non-toxic, non-flammable, and recyclable materials, operating efficiently at temperatures up to 1500°C. After rigorous testing, these materials have proven reliable for critical industrial applications and as effective energy storage for the grid. Each unit can store up to 20 MWh of energy with a remarkable 95% round-trip efficiency, and multiple units can be combined to meet the energy demands of larger facilities, charging in as little as two hours. This technology allows for seamless integration into existing industrial processes, enabling businesses to adopt it with minimal disruption.

With its innovative TCES technology, recent funding, and strong leadership under Pasquale Romano, Redoxblox is well-equipped to tackle the urgent challenge of decarbonizing industrial heat and energy storage. The company’s advancements represent a significant step toward a more sustainable energy landscape, crucial for achieving global decarbonization goals. As Redoxblox embarks on this new chapter, its efforts will play a vital role in creating a cleaner and more efficient energy future, ultimately reshaping the industrial energy landscape for generations to come.
