An outlook on deployment the storage energy technologies in iraq

Abstract

Abstract This study aims to analyze and implement methods for storing electrical energy directly or indirectly in the Iraq National Grid to avoid electricity shortage. Renewable energy sources are changing with time and climatology conditions. Therefore, the impact of weather on power generated and demand using renewable energy is considerable. This issue becomes a new motivation for developing new energy storage systems independent of time and weather. Stored energy ensures the smooth and clean transmission of electricity in conditions where the delivery may be interrupted or mismatched. Storage energy technologies are intelligent as they diversify energy sources, develop economic growth and produce more jobs. Technologies like Redox Flow Batteries (RFB), Pumped Hydro Storage (PHS), Compressed Air Energy Storage (CAES) and other forms were analyzed within this study. The PHS mechanical indirect electrical energy storage system is a great way to store large amounts of off-peak energy; however, it faces geographical challenges when siting such a development. The paper has strongly recommended the PHS to be used in Iraq due to the unique characteristics of 20,000 cycles, 33 year lifespan, and 80% round trip efficiency. Although Iraq has two rivers, salinity and water management must take into consideration. The study also suggested that RFB and CAES can be added to the network. The future work will concentrate on employing biomass technology, protection and improving the life span of these technologies. Solar and Wind technologies are excluded, as many research papers are available online.
