When fully operational in 2025, it can remove 3,650 tonnes of CO2 from the ocean yearly.
SINGAPORE – As part of its efforts to tackle climate change, Singapore will be constructing the world’s largest facility to boost the ocean’s ability to absorb carbon dioxide from the atmosphere.
Both plants, which were set up in April 2023, are each able to remove some 100kg of the greenhouse gas from the ocean each day. The planned facility will also produce some 300kg of hydrogen daily, which can power the plant or be used in other industrial applications. PUB said the processed seawater will be further treated to reduce any potential impact to the marine environment. “PUB and Equatic will closely monitor any environmental impact arising from the operations of the demonstration plant via an independent consultant,” said its spokesman.
RunningTide, based in Maine in the United States, signed an agreement with Microsoft, which aims to be carbon-negative by 2030, to remove and store some 12,000 tonnes of CO2 from the ocean by growing seaweed, which absorbs CO2 as it grows. However, the increased uptake of CO2 has caused warming oceans, ocean acidification and oxygen loss, destroying many marine ecosystems and habitats. This affects the ocean’s ability to continue providing food, supporting livelihoods and insulating the world from the worsening impacts of climate change.
