Abstract
In various embodiments, systems for providing a constant electrical output from a compressed gas energy storage and recovery system include a hydraulic-pneumatic energy storage and recovery system configured to provide a varying pressure profile at least at one outlet, a hydraulic motor-pump in fluid communication with the outlet, and a control system for enabling the constant electrical output by controlling at least one of pressure, piston position, power, flow rate, torque, RPM, current, voltage, frequency, or displacement per revolution.
