In 2023, Canadian firm Planetary released 280 tonnes of an antacid-like mineral into Halifax Harbour over two months to test whether more alkaline seawater can absorb extra CO₂
An experiment in Halifax Harbour introduced antacid minerals to enhance ocean alkalinity. This process aimed to increase the ocean's capacity for absorbing atmospheric carbon dioxide. Researchers studied the changes in seawater chemistry and carbon concentration during the trial. The method could potentially remove substantial amounts of carbon dioxide from the atmosphere. Scientists are cautiously assessing its environmental impacts and scalability for climate solutions.
