Another carbon sequestration project is being undertaken by a team from the University of Leicester in England and the British Geological Society. This project is working on a means of storing CO2 in a solid form as a gas hydrate and also in liquid form as liquid CO2 under a cap of hydrate cemented sediments. To do this, the CO2 and water would be frozen at low temperatures and high pressures to produce a crystaline structure.

The FutureGen alliance is a public-private partnership to develop an integrated coal fired power plant that also produces hydrogen and features carbon sequestration. President Bush announced plans to fund a $1 billion, ten-year project to build a demonstration plant in 2003. Since then South Korea and now China have also joined the alliance. The plant is expected to be the world's first zero-emissions fossil fuel powered plant thanks to the sequestration.

As part of its plan to expand oil production from the northern Alberta tar sands, Shell Canada wants to capture and sequester carbon dioxide emissions from the facilities. Unfortunately, in spite of the high oil prices and associated profits which are prompting the expansion in the first place, Shell still wants some tax breaks to help pay for the sequestration program. CEO Clive Mather says the carbon capture program, would allow for expanding the oil production without increasing greenhouse ga

Christopher Lydon hosts a public radio show called Open Source and recently had a show on global warming and coal. One of the guests was Julio Friedmann, Head of the Carbon Storage Program at Lawrence Livermore National Laboratory. Friedmann talked about geologic sequestration of carbon dioxide. The idea is to separate carbon dioxide from the exhaust stream of coal or gas fired power plants, and then pump it deep underground. Apparently the carbon separation procedure has been understood for 70
