An accumulator for storing pressurized air underwater comprises a reservoir anchored to the bottom of the sea or suspended underwater, and a pair of inlet and outlet passages for respectively supplying and discharging pressurized air into and out of the reservoir. The reservoir has an opening or openings through which water is flowable into and out of the reservoir. The anchored reservoir has a winch for winding or unwinding a chain connected to a weight, the winch being energizable when the water head at the reservoir changes so as to maintain pressurized air in the reservoir under constant pressure. The reservoir which is suspended has a plurality of floats that are inflatable or rigid with holes and are movable up and down as the water level in the reservoir varies so as to stabilize the air pressure in the reservoir.
