Energy storage is gaining relevance due to the increasing participation of renewable energy sources in the grid. The inherent intermittent nature of solar and wind energy made use storage necessary in order to to provide energy when it is needed. FibAirTech offers an energy storage clean-tech technology based in the power of the compressed air. Using well known technologies as compression process and cutting edge materials, energy can be stored using mainly air. A particular arrangement in the system components can be customized for different sizes and applications. Simple air can help to use in a better way renewable energy, without CO2 emissions and avoiding use of Rare Earth Materials (commonly used en batteries) which have high environmental and social impact.
