New publication suggests energy storage needs new policy incentives

Our new article in IJPSE identifies economic and environmental potential for EV battery reuse in large scale stationary applications, but shows that existing renewable energy policy incentives don't work for implementing energy storage. 


Economic and environmental analysis of a green energy hub with energy storage under fixed and variable pricing structures

Abstract

With the increased use of intermittent renewable power generation, including wind and solar, the need for energy storage is increasing. Re-purposed hybrid electric vehicle lithium ion batteries have been shown to have energy storage potential at a reduced financial cost. In a two stage MatLAB simulation, a Net Zero grid connected facility is created, and then the yearly electricity price of is calculated under various scenario using two different pricing structures, fixed Feed-in Tariff (FIT) and market. The facility under consideration is a commercial distribution center with refrigeration, onsite generation of hydrogen for fuel cell powered forklifts, solar and wind power generation, and re-purposed batteries for energy storage. The FIT mechanism is shown to be a deterrent to implementing energy storage onsite, as well as to increasing the use of locally generated power. The mechanism also negatively influences the indirect electricity emissions, which is not consistent with environmental objectives.
