Distributed Energy Storage

The main objective of the daily energy storage project is to develop energy storage technologies for the kWh energy range capable of producing at least several kW of power. This energy storage range should be sufficient for household daily energy storage and for grid reliability applications. The average Alberta household consumes ~20 kWh electricity per day (~7200 kWh of per year, www.solaralberta.ca). Assuming all the energy needs to be stored for use during nighttime and a discharge-charge efficiency of 70%, 28.57 kWh will need be stored in the energy storage system. Further, assuming a 4 h discharge time, the power output requirement would be 7.15 kW. The storage system used should be able to sustain at least ~2000 cycles (assuming replacement every 5 years). 

Many energy storage technologies can be used for daily storage, however, based on current expertise at the University of Alberta, the following two technologies will be developed: a) Flywheel energy storage systems (FESS) and b) Metal-air (in particular zinc-air) battery systems (MAB)
