Singapore-based Temasek Trust’s Catalytic Capital for Climate and Health has led a $11.6 million Series A financing in marine carbon removal startup Equatic, joining forces with Kibo Invest and a group of global backers to scale seawater electrolysis technology that strips carbon from the air and produces green hydrogen.

The funding exceeded Equatic’s $10 million target and will go toward engineering its first commercial plant capable of removing 100,000 tonnes of carbon dioxide a year, as well as accelerating manufacturing, commercialization and technological development.

Scaling Dual-Output Climate Technology

Equatic’s patented process speeds the ocean’s ability to absorb and store carbon while generating hydrogen with a net-negative carbon footprint. Pilots in Los Angeles and Singapore have drawn strong interest from hydrogen buyers and carbon credit markets.

The company has adopted ISO-14064 standards for monitoring and verification, validated by carbon registries Isometric and Puro.earth, making it one of the few marine carbon removal firms able to issue high-quality credits with full transparency.

“Equatic’s technology and approach exemplify the type of bold and scalable innovation that aligns with C3H’s mandate,” said Ryan Tan, head of C3H. “We are delighted to support Equatic’s goal in advancing promising climate mitigation solutions.”

From Contest Winner to Commercial Player

Equatic, formerly SeaChange, won the Temasek Foundation’s Liveability Challenge in 2021, securing S$1 million in funding. It later piloted its technology with Singapore’s national water agency PUB and in 2024 became a finalist for The Earthshot Prize.

Temasek Trust has supported Equatic from its philanthropic beginnings to the current investment round. “The Temasek Trust ecosystem has been a foundational partner,” said founder and Chief Technology Officer Gaurav N. Sant.

Growing Demand for Carbon Removal

Investors in the round included Stacey Nicholas, the Aga Khan Foundation, filmmaker Adam McKay and Lee Cooper. Equatic has also been supported by Grantham Neglected Climate Opportunities.

Kibo Invest CEO James Marshall said the company addressed “two critical needs: decarbonisation and clean energy.”

C3H focuses on early-stage innovators in climate and health, aiming to fast-track solutions for a low-carbon future.
