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 hydratewithout any additional energy added, thus providing energy production and safe long term storage of CO2The concept have been proven
and verified through numerous experiments worldwide. We have collaborated with COP on experiments and theory for 10 years
