Progress in understanding the potential role CO2 storage

Many ideas have been proposed for storage Of CO2 from anthropogenic sources and the first examples are now in use. As part of its on-going work on CO2 capture and storage technologies, the IEA Greenhouse Gas R&D Programme investigates such ideas, to understand their potential capacity and cost, as well as their likely environmental impact and practicality. This paper presents the results of work on a number Of CO2 storage options including: depleted oil and gas fields, unminable coal measures, mineral carbonates, and hydrates. In addition, work is described on establishing collaborative monitoring of the storage of CO2, and on investigating public concerns about injection Of CO2 into the deep ocean.
