Equatic’s Revolutionary Oxygen-Selective Anodes: Scaling Carbon Removal and Green Hydrogen Generation

In a groundbreaking development for climate solutions, Equatic has unveiled the U.S. manufacturing of oxygen-selective anodes (OSAs), a major technological leap that could transform the future of both carbon removal and clean hydrogen production.

This innovation, developed by Dr. Xin Chen at UCLA, has been made possible with significant support from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E).

The OSAs represent a pivotal advancement in seawater electrolysis, unlocking the potential for gigaton-scale carbon removal while generating green hydrogen at an affordable cost.

This new technology eliminates the need for pure water, traditionally a key element in the electrolysis process, and instead utilizes the ocean’s abundant saltwater resources. “Equatic’s OSAs eliminate the process’s dependence on pure water, and it taps into the world’s most abundant water resource instead: the ocean,” explained Dr. Doug Wicks, ARPA-E’s program director. This shift not only enhances efficiency but also opens new doors for scaling this technology to a global level, bringing about significant benefits for coastal regions.

The first manufacturing facility for these new anodes will be located in San Diego, California, where a highly specialized team will be responsible for producing the OSAs.

The facility is expected to reach full operational capacity by the end of 2024, with plans to manufacture 4,000 units annually. This local production will not only help scale Equatic’s technology but also fuel job creation and expand the clean energy economy in Southern California.

“This U.S. discovery will be manufactured by a team of highly skilled technicians in San Diego, fueling our domestic clean economy and creating ripple effects that will be felt worldwide,” added Wicks.

The Science Behind Oxygen-Selective Anodes

In 2021, Dr. Chen and his team at UCLA embarked on a project to develop a seawater electrolysis process that avoids the production of chlorine gas, a major hurdle in the scalability of clean hydrogen generation. Chlorine gas poses serious health and environmental risks, which had previously limited the use of seawater for electrolysis on a large scale. With a $3 million ARPA-E grant awarded in June 2022, Chen’s team made significant strides in this area by designing electrodes that don’t react with the salt in seawater, thus preventing the release of harmful chlorine gas.

This scientific breakthrough forms the foundation of Equatic’s ability to scale their technology to gigaton levels of carbon removal. “This breakthrough is the crux of Equatic’s ability to scale to gigaton volumes and has global implications,” stated Edward Sanders, Equatic’s chief operating officer. By reducing costs and overcoming environmental challenges, the company’s technology is poised to play a critical role in the world’s transition to clean energy.

Dual Benefits: Carbon Removal and Green Hydrogen

The dual-revenue model created by Equatic’s process is key to its scalability. By combining electrolysis with direct air capture, the company can produce both green hydrogen and remove carbon dioxide, generating two highly valuable products in one process. The revenue from clean hydrogen helps subsidize the cost of carbon removal, making the entire process more affordable and scalable. Equatic aims to bring the cost of carbon removal down to less than $100 per tonne by 2030, a goal that would have a major impact on global climate efforts.

The OSAs are also highly recyclable, which further enhances their sustainability. After three years of use, the anodes simply need to be recoated with catalysts made from affordable, earth-abundant materials, reducing the overall environmental footprint of the technology. This innovative approach will be key as the company scales operations globally.

Expanding Global Operations

The impact of this breakthrough will be felt worldwide as Equatic integrates OSAs into its upcoming commercial-scale plants. The company’s first demonstration plant, Equatic-1, will be located in Singapore, with the first commercial-scale plant set to open in Quebec. Together, these facilities will remove 109,500 tonnes of CO2 and generate 3,600 tonnes of green hydrogen per year by 2026. As more plants come online, the potential for scaling carbon removal and hydrogen production will only increase, making a significant contribution to global climate goals.

Equatic’s technology represents a significant shift in how the world can tackle both carbon removal and clean energy generation. The ability to produce green hydrogen without relying on pure water and simultaneously remove CO2 from the atmosphere opens the door for coastal regions to play a critical role in the clean energy transition. As Sanders noted, “With OSAs in production, Equatic is ready to help coastal regions around the world play a critical role in the clean energy transition.”

Ongoing research by Dr. Chen and his team will continue to refine and improve the performance of OSAs, driving down costs and ensuring a sustainable supply chain for the future. With domestic production and a clear path toward scalability, Equatic is poised to lead the charge in carbon removal and green hydrogen generation.

As the company prepares for the full-scale rollout of its technology, Equatic continues to pave the way for a cleaner, more sustainable future. The implications of this innovation are profound, not only for the U.S. but for the entire world as the clean energy revolution accelerates.

By tapping into the vast resources of the ocean and innovating within the field of electrolysis, Equatic has set itself apart as a leader in the carbon removal space. As the technology develops and more plants come online, the potential to meet global climate goals becomes increasingly realistic, bringing us closer to a future where clean energy and carbon reduction are more accessible and scalable than ever before.
