A Numerical and Graphical Review of Energy Storage and Energy Production Technologies

This is the accompanying excel spreadsheet for the paper entitled: A Numerical and Graphical Review of Energy Storage Technologies (Energies 2014/15). The paper takes a looks at and compares the landscape of energy storage devices.

Solutions across four categories of storage, namely: mechanical, chemical, electromagnetic and thermal storage are compared on the basis of energy/power density, specific energy/power, efficiency, lifespan, cycle life, self-discharge rates, capital energy/power costs, scale, application, technical maturity as well as environmental impact. It’s noted that virtually every storage technology is seeing improvements. The paper provides an overview of some of the problems with existing storage systems and identifies some key technologies that hold promise.
