A low-cost electro-gen solvent for carbon dioxide sequestration

An innovative concept for one of the lowest-cost carbon dioxide capture methods from power plants and other carbon-dioxide-emitting facilities is provided here. The concept is to use a novel electro-thermo-chemical regeneration approach which will generate a product solution containing hydroxyl ions for absorbing the flue gas CO2. This may work with existing flue gas desulfurizing equipment to minimize the cost of carbon capture. The process involves the use of low-cost make-up reagents which are capable of providing credits for partial mineralization of CO2, thus offsetting some of the costs for carbon capture and sequestration. The process presents the possibility of making this a low-cost on-site mineralization with cost offsets.
