A comparative survey of energy storage in communications infrastructure

What is it about?

As communications technology is ubiquitous, and energy savings are ever more crucial in communications and data storage infrastructures, it is timely to revisit the technologies used for energy storage. This multidisciplinary paper especially focusses on the specific requirements onto energy storage for communications and data storage, derived from traffic, climate, high availability, and resilience, irrespective from energy sources used. It also addresses techno-economic, environmental & emissions tradeoffs offered by a model, and concludes with discussing future energy storage technologies.
