A drop in the ocean: does experimental technology hold the key to saving the world’s seas?
<p>Investment is pouring into companies promising to geoengineer a rapid change in the pH of our waters – but critics are concerned at the speed at which unproven methods are being adopted</p><p>In October 2024, a US company called Ebb Carbon announced <a href="https://www.businesswire.com/news/home/20241024346899/en/Ebb-Carbon-Signs-Deal-With-Microsoft-for-CO2-Removal">the world’s largest marine carbon removal deal</a> to date, signing a multimillion-dollar agreement with Microsoft to try to help fix a very real problem in the world’s seas: ocean acidification.</p><p>Ebb plans to use a method called electrochemical ocean alkalinity enhancement (OAE) to mimic the natural process of ocean alkalisation – in other words, it wants to add huge amounts of alkaline materials to ocean waters that scientists now know are acidifying at an alarming rate<strong>.</strong></p> <a href="https://www.theguardian.com/environment/2025/jun/10/ocean-does-experimental-technology-saving-seas-acidification-geoengineering">Continue reading...</a>
