Introducing magnesium hydroxide into St Ives Bay for carbon capture

An independent review deemed plans to introduce magnesium hydroxide into St Ives Bay to combat climate change as "very low risk". Proposed by Planetary Technologies and South West Water, the trial aims to sequester carbon dioxide from the atmosphere by adding the alkaline mineral to the sea. While awaiting approval from the Environment Agency, key recommendations include additional sampling, monitoring, and refining of concentration calculations. Critics, including the Seal Research Trust, call for cautious testing, expressing concerns about potential impacts on marine life and the seabed. Planetary Technologies emphasises the potential for significant carbon removal, while South West Water prioritises environmental protection. (BBC),
