Geological formations for CO2 storage

Geological formations for CO₂ storage are natural underground rock layers that can trap and hold carbon dioxide safely. These include depleted oil and gas fields, deep saline aquifers, and unmineable coal seams. They provide a secure environment where CO₂ can be injected and stored permanently, preventing it from escaping into the atmosphere. The rocks act like natural seals, ensuring the gas remains contained over long periods, which helps mitigate climate change by reducing greenhouse gases in the air. Proper site selection and monitoring are essential to ensure safe and effective storage.
