Turning Oceans Into Climate Solutions, Equatic Scores $11.6M Boost

Equatic, a leader in combined carbon dioxide removal and green hydrogen production, has secured US$11.6 million in its Series A funding round, led by Catalytic Capital for Climate and Health (C3H), an investment arm of Temasek Trust, and Singapore-based Kibo Invest. The round, which also drew participation from other global investors, will accelerate the scale-up and commercialisation of the company’s patented seawater electrolysis technology. This innovation captures atmospheric carbon dioxide while producing green hydrogen in a single process, offering a scalable solution to two major climate challenges and they are carbon removal and clean energy production.

The new funding will support the development of Equatic’s first commercial facility capable of removing 100 kilotonnes of CO₂ annually, along with further commercialisation, manufacturing, and technical advancements. Since launching in 2023, the company has operated pilot plants in Los Angeles and Singapore, is building a demonstration plant in Singapore called Equatic-1, and plans a commercial-scale plant in Canada. Equatic has received multiple recognitions, including being named a semifinalist for the U.S. Department of Energy’s CDR Purchase Prize and a finalist for The Earthshot Prize in 2024. It also developed oxygen-selective anodes enabling scalable hydrogen production from seawater and has adopted ISO-14064 MRV standards, validated by registries Isometric and Puro.earth, making it one of the few marine companies issuing high-quality, fully auditable carbon removal credits. Buyers include Boeing and other major industrial firms committed to decarbonisation.

Equatic’s approach has drawn praise from industry leaders for its cost efficiency and scalability. C3H’s head, Ryan Tan, described the technology as bold and impactful, while Kibo Invest’s CEO, James Marshall, called it an opportunity to advance deep-tech innovation in decarbonisation and clean energy. With the backing of catalytic capital and strategic partners, Equatic aims to rapidly advance from pilot projects to full-scale commercial operations, potentially shaping global climate mitigation efforts for decades.
