Equatic

Area of Impact:
Canada, Singapore, USA

Equatic is rewriting the future of Carbon Removal by working hand in hand with nature. Their carbon dioxide removal (CDR) technology uses the power of the ocean to lock away harmful CO2, offering a safe, scalable solution to the climate crisis.

The Challenge

The ocean is our planet’s largest carbon sink, which absorbs about 30% of the CO2 we release into the atmosphere. But the ocean is struggling to keep pace as we emit more and more carbon. The result? A dangerous imbalance that’s driving us toward catastrophic climate change.

Current carbon removal solutions aren’t enough—they’re often small-scale, expensive, and plagued by issues of transparency and verification. The world needs a breakthrough: an affordable, large-scale CDR solution that doesn’t harm the environment and uses low or renewable energy.

Their Solution and Impact

Equatic is that breakthrough. Their patented technology uses a process called electrolysis to turn CO2 into a stable, solid form carbonate material—much like naturally-formed sea shells. It’s a method that permanently removes carbon by extracting CO2 from seawater, transforming it into carbonates, and returning the cleaned water to the ocean, unharmed. Think of it as nature turbo-charged—the process is 99,000 times faster than the ocean’s natural ability to absorb CO2.

And here’s the exciting thing: the process also produces clean hydrogen fuel, further reducing emissions and providing a green energy source to power Equatic’s operations.

They work in shoreline plants that can be set up anywhere there’s a coastline and energy supply (preferably renewable), providing a scalable solution to one of the planet’s most pressing challenges. At full commercial scale, Equatic has the potential to transform industries, create jobs, and fuel green energy economies—while actively healing the climate. Through the sale of carbon credits, clean hydrogen, and even building materials made from the captured carbon, Equatic creates value while making a measurable impact on global emissions.

Led by Gaurav Sant, a pioneer in carbon management and the Director of UCLA’s Institute for Carbon Management, Equatic is aiming for significant impact. Pilot projects are already successfully operating in Singapore and Los Angeles with over 75,000 tonnes of CO2 removal under contract. For comparison, a flight from London-Los Angeles-London emits 3.5 tonnes CO2. At the same time, they generated 2,000 tonnes of clean hydrogen.

These small-scale operations are just the beginning. With costs expected to drop to as low as $30 per tonne of carbon removed — far below the current $100 per tonne benchmark — as a result, Equatic is poised to scale rapidly.

The Future

The highly regarded founding team have received backing from Chan-Zuckerberg, Boeing, DeepSky, Arup and the US Department of Energy. With a $30 million offtake agreement from Boeing and plans for commercial-scale plants in Singapore and Quebec by 2026, they’re well on their way to achieving their ambitious goal of removing 5 million tonnes of CO2 by 2030. These plants will not only remove carbon but also generate clean hydrogen, helping to decarbonize industries and drive the transition to a more sustainable future.

With their technology and strong partnerships, Equatic is positioned to be a key player in global carbon removal efforts, setting the stage for a cleaner, greener, and more resilient planet.
