Arithmetic of a recipe the coal, shale gas and coal seam gas industries don't want you to know
- Combine coal and/or biomass containing 180 kilograms of carbon with 270 kilograms of water to produce 120 kilograms of methane and 330 kilograms of carbon dioxide.
- Separate and store the 330 kilograms of carbon dioxide.
- Compress or liquefy the 120 kilograms of methane to use as fuel in a compressed natural gas (CNG) vehicle or in a liquefied natural gas (LNG) vehicle, truck, train or ship.
- Alternately use the 120 kilograms of methane as fuel in a gas power station to produce 1 megawatt-hour of electricity with emissions of just 330 kilograms of carbon dioxide. A carbon price of $23 per tonne of carbon dioxide emissions would add nearly 1 cent to the cost of each kilowatt-hour of electricity generated.
IN SALAH
Industrial-scale carbon capture and storage (CCS) in actionIn Salah, an industrial-scale CCS project in Algeria has been in operation since 2004. More than three million tonnes of CO₂, separated during gas production, have been securely stored in a deep saline formation. BP, Sonatrach and Statoil, the project operators, aim to store a total of 17 million tonnes over the next 20 years. (Read more...)
