A system including a solid propellant gas generator for generating closing pressure for an oilfield closing device is disclosed. The system provides a reliable source of hydraulic power for emergency operation of blowout preventers, diverters and the like. A solid propellant gas generator is actuated by an actuating signal. Resultant high pressure gases are applied either directly to the oilfield closing device, or to a hydraulic reservoir operably forcing hydraulic fluid to the closing device.
