Fossil fuels are one of the cheapest sources for power plants if CO2 produced during the process can be disposed in a cheap and permanent way to make them environmentally safe. Mineral carbonation is one of the most benign and permanent means of carbonsequestration. 1 Brucite (Mg (OH) 2) is a model system being investigated as it is presumably the active species in more complex minerals eg serpentines, to be used as feed stock materials for carbon sequestration. The reactivity of partially dehydroxylated brucite..
