Combined carbon dioxide (CO₂) removal and green hydrogen production company Equatic has closed its Series A funding round, raising $ 11.6 million. The funding round was led by Temasek Trust’s catalytic vehicle, Catalytic Capital for Climate and Health, and Singapore-based private investment office Kibo Invest.

Equatic will utilize the funds to accelerate the engineering scale-up and commercialization of its patented seawater electrolysis technology. The company claims to produce green hydrogen from seawater while capturing and storing carbon dioxide.

The funding will also support the ongoing engineering of the company’s first 100-kiloton CO₂  removal commercial facility. It will also aid in further commercialization, manufacturing, and technological development of Equatic’s solutions.

Gaurav N. Sant, Founder and Chief Technology Officer at Equatic, said, “This investment marks a pivotal moment for Equatic, enabling us to significantly scale our production capabilities and accelerate our mission to deliver durable carbon removal at scale.”

“Truly innovative carbon management technologies are needed to mitigate climate change before the consequences become irreversible,” said John Browne, Chairman of Equatic’s Advisory Board, and Founder and Chairman at BeyondNetZero. “By removing carbon dioxide and simultaneously generating green hydrogen, Equatic’s solution provides unique advantages in terms of cost and scalability.”

Equatic has deployed its technology at two pilot plants in Los Angeles and Singapore. It is expanding its operations with Equatic-1, a demonstration plant in Singapore. The company is also setting up a commercial-scale plant in Canada. Its proprietary technology is designed to capture atmospheric CO₂ to produce green hydrogen through what it claims to be a single and scalable process.

A Cornell University-led research team claimed to have developed a sustainable and low-cost method to produce carbon-free green hydrogen using just sunlight and seawater as inputs.

In 2024, engineers from the University of Illinois, Chicago, developed a novel method to produce hydrogen from water utilizing only solar power and agricultural waste such as manure or husks. This novel technique claimed to reduce the energy required to extract hydrogen from water by 600%.
