Stanford Chemists Unveil Low-Cost Carbon Dioxide Removal Method

Stanford University chemists have announced a new, practical, and low-cost method for permanently removing atmospheric carbon dioxide, a primary contributor to global warming. The process, detailed in a February 19th study in *Nature*, involves using heat to convert common minerals into materials that actively capture carbon dioxide directly from the air and permanently store it. These reactive materials can be produced using standard kilns, similar to those used in cement manufacturing. According to Professor Matthew Kanan, this method addresses the slow reactivity of naturally occurring minerals, making it a uniquely scalable solution to counteract greenhouse gas emissions. The Earth possesses abundant minerals capable of capturing CO2, but their natural reaction rates are insufficient to combat human-caused emissions. This innovation aims to accelerate that process, offering a potentially transformative approach to carbon capture and climate change mitigation.
