In this chapter, the current status of CO2 storage is discussed, firstly by introducing each of the main geological storage types, saline aquifers, depleted oil and gas fields, and mineralization in basalts, and secondly by introducing the key areas of project development: characterizing a site and the risk management and monitoring of a site. Firstly,

Onshore Geologic Storage of CO 2
Science, 2009The possibility that substantial quantities of CO 2 can be injected into subsurface porous rock formations has been investigated sufficiently to show that pore space available to contain the CO 2 is abundant. Multiple rock types and physical mechanisms can be used to trap the CO 2

International Developments in Geological Storage of CO2
Exploration Geophysics, 2006Geological storage of captured CO2 is a new way of reducing greenhouse gas emissions to protect the climate, but is based on the established technology associated with injection of fluids underground. The geological formations of interest for this technique include operational and depleted oil and gas fields, and deep saline aquifers.

Hydraulic Forces in Geological Storage of CO2
Proceedings, 2014Traditionally the ‘storage’ of CO2 in the deep subsurface has been seen as (1) a hydrostatic process whereby migration of sequestered CO2 is driven by upwards and downwards directed vertical buoyancy forces, and (2) that the buoyancy driven movement is upwardly constrained by aquitards (caprocks).

CO2 geological storage risks management
2013The development of CO2 geological storage at large scale is dependent on the management of potential risks for each specific storage site. Risks management is mainly made of risks identification, assessment, treatment and monitoring. Demonstrating the safety of a specific storage site is challenging for several reasons.
