Abstract. The quality of life today is dependent upon access to a bountiful supply of cheap energy. For a sustainable future, the energy should be derived from non-fossil sources; ideally, it should also be reliable and safe, flexible in use, affordable, and limitless. This paper examines the present global use of energy in its various forms
Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated.
Advanced energy storage technologies make that power available 24/7. To compete with other forms of energy generation and storage, it needs to become more efficient. One way to achieve this is
