Scope and mission
GESTCO

• Where in Europe
• can we store CO2 from
• industrial sources ?

• And where in Belgium ?

• Coal mines ? Then study it !

False start

• Pinitial Phydrostatic
• depth gt 800 m
• permeability good
• geometry simple

• Pinitial Patmospheric 0
• depth partly lt 800 m
• permeability very good
• geometry complex
