Abstract
The random nature, abrupt variations of electricity generation, and high differences between the peaks and valleys of the demand curve and the generation curves of wind farms and photovoltaic generators can be avoided by means of electricity storage in batteries or hydrogen. The storage would bring many benefits to the electrical grid. However, present acquisition costs of batteries and hydrogen components are too high so that these systems cannot be profitable economically. In terms of energy, the storage in batteries is much better than in hydrogen because the roundtrip efficiency is much higher. In a matter of years, some forms of battery technology could be competitive for these applications.
