Singapore Prepares to Transform Ocean Chemistry

In a groundbreaking move against climate change, Singapore is set to unveil the world’s largest facility dedicated to enhancing the ocean's capacity to absorb carbon dioxide (CO2) by early 2026. The Equatic-1 demonstration plant, located in Tuas, marks an ambitious collaboration between Singapore's national water agency, PUB, and U.S. startup Equatic, known for its innovative ocean-based carbon removal technology.

Innovative Technology for a Sustainable Future

This groundbreaking facility will utilize cutting-edge technology to modify the chemistry of seawater, efficiently extracting dissolved CO2 for long-lasting storage. By discharging this treated seawater back into the ocean, the facility aims to enhance the seawater’s capacity to absorb even more CO2 from the atmosphere.

The Potential Impact on Climate Change

If successful on a larger scale, this technology could significantly combat the greenhouse gas responsible for climate change. Currently, the ocean absorbs approximately 30% of CO2 emissions stemming from human activities. With the rise of the Equatic facility, the ocean’s natural defenses against global warming could receive a crucial boost.

Investment Sparks Excitement!

Recent interest in this innovative project has surged among investors, with Temasek Trust's Catalytic Capital for Climate and Health (C3H) co-leading a Series A funding round of approximately $11.6 million. This funding will aid in scaling up Equatic’s first commercial facility—originally set for North America—while propelling technological development.

A Facility Designed for Effectiveness

Initially, the Singapore facility aims to extract 1 tonne of CO2 daily, with a full operational capacity of 10 tonnes, equivalent to removing roughly 870 cars from the roads. By leveraging electrical currents and specific chemical reactions, the plant will convert seawater into valuable hydrogen and solid minerals, permanently binding CO2 for thousands of years.

Contributing to a Greener Future

The $20 million Equatic-1 facility isn’t just about carbon capture; it also aims to produce up to 300 kg of clean hydrogen daily, which can serve as a sustainable energy source. Through effective collaboration among PUB, the National Research Foundation, and UCLA’s Institute for Carbon Management, this project sets a precedent for future green technologies.

Navigating Environmental Concerns

Despite its potential, scientists do caution about the possible impacts of CO2 extraction on marine ecosystems. Experts warn that altering ocean chemistry could pose risks to marine life. Nevertheless, PUB assures thorough monitoring and testing to ensure compliance with strict environmental standards.

The Road Ahead: Challenges and Opportunities

While marine carbon removal technologies are still in their infancy, early pilot tests show promise. Previous smaller projects have successfully captured CO2, paving the way for this ambitious demonstration plant. As the technology scales, continuous collaboration with environmental agencies will be essential to mitigate any negative impacts.

A Leap Towards Environmental Responsibility

PUB aims to reach net-zero emissions by 2045, ahead of Singapore's national goal. In tandem, efforts are underway to replace fossil fuels with renewables and enhance energy efficiency in water treatment. With plans for solar panels on reservoirs and investments in innovative research, Singapore is positioning itself as a leader in sustainable practices.
