  1. Gas Hydrates: A Major Energy Resource: Bjørn Kvamme, UiB http://geology.usgs.gov/ USGS estimates that methane trapped in hydrate might amount to twice all known resources of free fossil fuels

  2. MRI High Pressure Cell Pore Pressure Pumps Core Plug Pore Pressure In CH4 t Ou In CO2 t MRI Magnet Ou Confining Pressure Confining Pressure Insulated Lines Pump P Cooling Bath Reciprocating Pump Injection of CO2 into natural gas hydrate (ice-like structure containing 14% CH4 in a volume similar to ice) leads to conversion into a mixed hydrate with release of up to 75% of in situ hydrate without any additional energy added, thus providing energy production and safe long term storage of CO2 The concept have been proven and verified through numerous experiments worldwide. We have collaborated with COP on experiments and theory for 10 years Experimental set-up for formation and reformation of hydrate under MRI monitoring Water in hydrate is invisible in the magnetic field. Free CH4 gas is visible. Injection of CO2 into hydrate releases methane from hydrate Bentheimer sandstone, 10 cm long 4 cm diameter and a spacer for free fluid volume
