Abstract
Presently disclosed is a power production plant that is operable to store and generate power. In a 'charge mode' (when electricity price is low), an air separation unit (ASU) cools and liquefies ambient air into liquid oxygen (LOx), which is then stored in a storage vessel. In a “discharge mode” (when electrical price is high), the stored LOx is used by the power production plant to combust a fuel and form a combustion product stream that can be expanded in a turbine to generate power. The power production plant particularly can utilize carbon dioxide as a recycled, circulating or working fluid so that substantially all carbon dioxide produced in the power production can be captured.
