Energy Storage

Energy Storage The demand for energy varies with time. One reason for this is that certain human activities must be performed at definite times. If such activities require the conversion of energy, they lead to more or less rigorous time patterns of energy demand. This is also true for energy demand not associated with any activity, such as that for space conditioning. The production of suitable energy forms from primary sources, however, may most conveniently follow a different pattern from that of demand. If variable, renewable energy sources are used, the level of energy production cannot be controlled. Storing energy for later use is a way of coping with these problems. Different situations lead to the desirability of having a variety of storage options, differing according to the form of energy needed, the quan ti ties of energy to be stored, the duration of storage, and the rate at which energy can be fed into or extracted from storage. Traditional energy-supply systems based, for example, on wood, coal, or oil involve storage of fuel. Usually, storage takes place before the main conversion step, but in a number of cases, primary conversion steps are performed before storage (for instance, the conversion http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Annual Review of Environment and Resources Annual Reviews

Abstract

The demand for energy varies with time. One reason for this is that certain human activities must be performed at definite times. If such activities require the conversion of energy, they lead to more or less rigorous time patterns of energy demand. This is also true for energy demand not associated with any activity, such as that for space conditioning. The production of suitable energy forms from primary sources, however, may most conveniently follow a different pattern from that of demand. If variable, renewable energy sources are used, the level of energy production cannot be controlled. Storing energy for later use is a way of coping with these problems. Different situations lead to the desirability of having a variety of storage options, differing according to the form of energy needed, the quan ti ties of energy to be stored, the duration of storage, and the rate at which energy can be fed into or extracted from storage. Traditional energy-supply systems based, for example, on wood, coal, or oil involve storage of fuel. Usually, storage takes place before the main conversion step, but in a number of cases, primary conversion steps are performed before storage (for instance, the conversion
