Piezo-Electric Valves for Hydraulic and Pneumatic Systems

It is not possible, as with solenoid valves, to specify power in watts. When a piezo valve has been switched on and the power supply interrupted, the valve remains on because charge carriers cannot flow past the interruption. To reset the valve, the transducer charge must be removed. This can be done by using buffer storage in another system

Electrical Energy Storage (EES) technologies

Hydro-power Pumped storage hydro-power is an efficient method of storing electricity for use at a later time. In pumped storage hydroelectricity, water is used to pump excess electricity from one reservoir to another, and vice versa. The electricity can then be used for industrial purposes, or it can be stored in a second reservoir, where it can be released during

A Review of Emerging Energy Storage Technologies

This energy is then reconverted into electrical energy for delivery to the power system when it is needed. The purpose of this white paper is to examine other emerging energy-storage technologies that are attracting renewed interest and attention.

Hot water systems

Larger electric storage water heaters are generally connected to off-peak electricity tariffs, where available, and heat water when electricity is at its cheapest (usually overnight or early morning). Electric storage water heaters can be used with solar PV to reduce energy use: refer to Electric PV powered hot water systems below.

Energy Storage | Applications | Capacitor Guide

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
