Experimental Model for the Study of Energy Conversion and Storage in Compressed Air. Backup Power Supplies

The use of renewable energy sources is a priority of the present in the energy transition that is imposed worldwide. Currently, renewable energy conversion technologies are in the technological maturity phase, but the problem of the intermittency of these energy sources has required the integration of energy storage systems produced in excess, in certain periods, systems that still pose problems for both researchers and dispatchers national of energy systems. The article deals with the case of supplying buildings where there no permitted interruptions in the electricity supply and their vital consumers (hospitals, clinics, etc.) are not foreseen. The experimental model approaches the solution of supplying the safety installations of the building and their vital consumers without the need for a backup source equipped with internal combustion engine or electrochemical battery.
