In recent years, deployment of standalone electricity systems to provide energy access in a rural context has increased rapidly. These systems typically incorporating variable renewables alongside electrical energy storage for consistent supply, and operate at a range of scales to provide a range of services. However, there has been relatively little analysis of storage technology choices made by providers of these systems, how this varies by application, how these are influenced by priorities of providers, and how these choices could be improved. Here, we present findings from a series of interviews with providers of off grid energy solutions on choice and availability of technologies, supply chains, realised costs, technology performance, environmental impact, and anticipated impact of future technology development. Based upon these, we make recommendations for regulators and individual companies on how technology choices and life cycle management could be improved.
