text: 4 years ago I worked on carbon sequestration projects in Australia and internationally. This included researching biological, geological and ocean sequestration of CO2. \n\nThere are pros and cons of all these processes, but I see many more pros.  You only have to look at Statoil's Sleipner Project in Norway - They have been sequestering CO2 into high saline aquifers since 1996.\n\nThey have, in fact stopped 1 million tonnes of CO2 from entering the atmosphere per year, the equivalent emissions of a 150MW  coal fired power plant in the US.\n\nI think it is a great solution until we can move towards a hydrogen economy.
