Why Energy Storage Decides the Pace of the Renewable Transition
Renewable capacity keeps getting added to grids worldwide, but the constraint that decides how much of that capacity actually gets used isn't generation — it's storage. Every gigawatt of solar or wind that can't be stored gets curtailed when supply outpaces demand. Grid-scale storage has become one of the fastest-growing segments of the energy system precisely because it's the piece that turns intermittent generation into something a grid operator can rely on.
That's the problem Energy Storage: Systems and Components by Alfred Rufer (CRC Press, 2026) is written to solve — not at the level of policy, but at the level of the hardware itself: batteries, supercapacitors, flywheels, compressed-air systems, and the power electronics that connect all of it to the grid. For engineers and energy programs building out storage capacity, the book treats sizing, conversion, and degradation as one integrated engineering problem rather than three separate ones.

Q&A
Q: Why is energy storage considered the bottleneck of the renewable transition?
A: Because storage determines whether renewable generation can be used when it's actually produced, or has to be curtailed and wasted when supply outpaces demand.
Q: What storage technologies does this book cover?
A: Electrochemical storage (batteries, supercapacitors), mechanical storage (flywheels, compressed-air systems), and thermal storage, together with the power electronics that interface them with the grid.
Q: Who should read Energy Storage: Systems and Components?
A: Electrical and power engineers, energy systems researchers, postgraduate students, and utility or grid planners working on storage design and integration.
Q: Is this a policy book or an engineering book?
A: It's an engineering reference — component-level and systems-level detail, not a policy discussion.
