US$11.6M Series A led by Temasek Trust’s Catalytic Capital for Climate and Health (C3H) will fund Equatic’s scale-up and commercialisation of seawater electrolysis technology for carbon removal and green hydrogen production.
Technology validated in Los Angeles and Singapore pilots; Equatic is one of the few marine companies issuing high-quality, registry-verified carbon removal credits.
Funding supports the first 100-kilotonne commercial facility, with strong offtake interest and backing from a global investor consortium.
Temasek Trust’s Catalytic Capital for Climate and Health (C3H) has led a US$11.6 million Series A financing round in Equatic, a company pioneering seawater electrolysis to both remove atmospheric CO2 and produce carbon-negative hydrogen. Singapore-based Kibo Invest co-led the round, alongside investors including Stacey Nicholas, the Aga Khan Foundation, Adam McKay, and Lee Cooper.
Equatic’s technology accelerates the ocean’s natural carbon absorption process, permanently storing CO2 while generating clean hydrogen in a single, scalable system. Validated through pilots in Los Angeles and Singapore, the process has drawn significant offtake interest. The company adheres to ISO-14064 standards for monitoring, reporting, and verification, with validation from both Isometric and Puro.earth registries.
The Series A proceeds will fund the engineering of Equatic’s first 100-kilotonne carbon removal facility, commercialization efforts, manufacturing scale-up, and further technological development.
“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 that offer permanent, durable carbon removal with green hydrogen production.”
James Marshall, CEO of Kibo Invest, added, “Equatic represents an exciting opportunity to scale deep-tech innovation that addresses two critical needs: decarbonization and clean energy.”
Equatic’s journey began in 2021 when it won Temasek Foundation’s The Liveability Challenge, securing S$1 million in catalytic funding and piloting its technology with Singapore’s national water agency PUB. In 2024, it was named a finalist for The Earthshot Prize.

“We are deeply grateful to all our investors and partners,” said Gaurav N. Sant, Founder and CTO of Equatic. “This financing catalyses Equatic’s mission to deliver cost-effective and durable carbon removal at scale.”
C3H’s backing reflects the growing momentum behind scalable, science-driven climate solutions, leveraging public, private, and philanthropic partnerships to accelerate the low-carbon transition.
