Equatic's Breakthrough: Extracting Hydrogen from Seawater While Removing Carbon Dioxide
Key Ideas
  • Equatic's technology extracts hydrogen from seawater without harmful chlorine production, while removing carbon dioxide, offering a dual environmental benefit.
  • The company's manufacturing in San Diego marks a significant step towards commercial hydrogen production and large-scale carbon dioxide removal.
  • Equatic's innovative anodes have been successfully tested in smaller pilot projects and are now set for larger-scale implementation in Singapore and Quebec.
Equatic has developed a groundbreaking technology that can extract hydrogen from seawater without producing harmful chlorine, solving a challenge that has persisted since the 1970s. This method also allows for the simultaneous removal of carbon dioxide from the atmosphere by converting it into a stable molecule. The company is now manufacturing their innovative anodes at a new facility in San Diego, which signifies a shift towards large-scale commercial production. Equatic's system uses electrolysis of seawater to produce hydrogen while capturing carbon dioxide from the air. By separating the seawater into acidic and alkaline streams, carbon dioxide is absorbed by the alkaline stream and converted into a stable form, enabling precise measurement of removed carbon dioxide. Additionally, the production of pure hydrogen can potentially offset the costs of carbon dioxide removal. After successful pilot projects in Los Angeles and Singapore, where significant amounts of carbon dioxide were removed and hydrogen produced daily, Equatic is moving towards larger-scale implementation. The new San Diego facility will initially produce 4,000 anodes per year and is set to be fully operational by 2024. This advancement will support Equatic's upcoming demonstration project in Singapore, aiming to remove 10 tons of carbon dioxide and produce 300 kilograms of hydrogen daily. Moreover, the company plans to establish a larger facility in Quebec capable of removing 300 tons of carbon dioxide per day, surpassing existing direct air carbon capture capacities.
