A pumped heat storage apparatus has a prime mover, a power take off, first and second fluid working machines functioning as a compressor () and as an expander (), a working fluid circulation pathway with high and low pressure sides, and high and low temperature heat exchangers (A-B). The heat exchangers operate using direct contact between gaseous working fluid and solid thermal storage media, such as glass beads, which move in opposite directions, typically using an augur (). The system is reversible between energy storage and energy recovery modes and when it reverses, the direction of movement of the working fluid and the thermal storage media reverses. The apparatus may very rapidly swap between energy storage and energy recovery while having a high capacity and energy throughout.

Apparatus and methods for the storage of energy as heat

A valve unit for a fluid working machine comprise a valve having a valve member (and optionally a valve seat), a valve actuator coupled to the valve member, and an electronic actuator controller which is integral to the valve unit and configured to actively control the valve actuator to thereby control the valve member.

The present invention provides a cooling system such as employed in cooling a heat source and a transmission system having said cooling system integrated therewith. The cooling system further includes a pump for supplying hydraulic fluid under pressure to a motor for driving a fan employed in the cooling process. In operation, a controller initiates operation of the pump such as to supply hydraulic fluid to said motor only when needed, thereby to improve the efficiency and controllability of the cooling system.

Cooling system and a transmission system having said cooling system integrated therewith

An object of the present invention is to provide a wind turbine generator and a tidal current generator equipped with a hydraulic transmission with a combination of a hydraulic pump and a hydraulic motor and which has a superior productivity and maintainability. The wind turbine generatorhas the hydraulic transmissionfor transmitting the rotation energy of a main shaftto a generator. The hydraulic transmissionincludes a hydraulic pumpof variable displacement type which is driven by the main shaft, a hydraulic motorof variable displacement type which is connected to the generator, and a high pressure oil line and a low pressure oil line which are arranged between the hydraulic pumpand the hydraulic motor. The hydraulic transmissionis at least partially constituted of a plurality of modules (Mto M).
