  • Steve Goldthorpe, an energy analyst based in New Zealand, has a radical suggestion: carbon dioxide should be dump in deep ocean trenches, where it should sit permanently as a liquid lake. The crucial point he says, is that once the carbon dioxide reaches a depth of about 3000 meters, its density exceeds that of water--so it will sink to the bottom and stay there. Goldthorpe used Google Earth to explore the seabed and identify a storage site. He found the Sunda trench around 6 kilometers under the ocean, just south of the Indonesian archipelago. "It is big enough to accommodate 19 trillion tonnes of liquid CO2, which is greater than all the CO2 from the total global fossil fuel emissions," he says.
