10 Transport of CO 2 no specific regulation transport under supercritical phase risks of corrosion USA: several thousand of km of pipes delivering CO 2 to EOR (Enhance Oil Recovery) operations
11 CO 2 geological storage Gt Gt 40 Gt Unmineable coal Saline aquifer Depleted oil & gas reservoirs Salt dome Pour la Science CO 2 plant CO 2 well CO 2 pipe CO 2 platform CO 2 droplets CO 2 lake CO 2 ship solid CO 2
12 CO 2 geological storage Hydrocarbon reservoirs (oil and gas) proven to be tight (to non reactive gas) geological traps well-known objects possible benefit through Enhanced Oil and Gas Recovery (EOR / EGR) Saline Aquifers huge porous volume: the biggest place for storage no drinkable water largely distributed generally poorly investigated Coals seams strong adsorption of CO 2 possible benefit through E Coal Bed Methane (ECBM) low permeability and porous volume
