🗞️ Driving the news: A new UK pilot project, SeaCURE, has begun operations on England’s south coast, aiming to remove carbon dioxide from seawater as a novel method of carbon capture
Funded with £3 million from the UK government, the facility in Weymouth seeks to test the feasibility of leveraging the ocean’s natural carbon-absorbing capacity to help address climate change

🔭 The context: The oceans already absorb about a quarter of all human-produced CO₂ emissions
Unlike conventional carbon capture methods that extract CO₂ from air or industrial sources, SeaCURE targets the higher concentrations of carbon dissolved in seawater
The pilot is one of 15 UK-backed projects investigating scalable carbon removal strategies to support the country’s net-zero ambitions

🌍 Why it matters for the planet: With global decarbonisation efforts lagging, scalable carbon removal technologies are increasingly seen as essential to meet net-zero targets
SeaCURE’s approach—removing CO₂ from seawater and returning low-carbon water to the ocean—offers a potentially energy-efficient and scalable method, particularly if powered by renewables
However, ecological risks, such as impacts on marine life, must be thoroughly understood and mitigated as the technology evolves

⏭️ What's next: The SeaCURE team is assessing the project's environmental impacts, particularly on marine organisms that rely on dissolved carbon
Early lab results suggest possible effects, but researchers are exploring mitigation strategies like pre-dilution
Future scalability depends on improving energy efficiency and proving environmental safety
If expanded to treat just 1% of ocean surface water, proponents claim the method could remove up to 14 billion tonnes of CO₂ annually—though this remains a distant and technically challenging goal

💬 One quote: “Capturing directly from seawater is one of the options… In the end the question of what to use, of course, will depend on the cost.” – Dr Oliver Geden, Intergovernmental Panel on Climate Change

📈 One stat: SeaCURE currently removes up to 100 tonnes of CO₂ per year—equivalent to the emissions from approximately 100 transatlantic flights
