It is aimed at solving the most important problem: the reduction (and ideally, the complete disappearance) of harmful emissions of greenhouse gases by coal-fired power plants. Please, learn about SASK Power if you care about CO2 capture. The essence of the project is the reconstruction of a coal-fired power plant with the introduction of carbon capture technology. This CO2 can be used to enhance the recovery of oil. Thus, coal-fired power units become waste-free and environmentally friendly.
