All about Energy Storage Technology
New and improved grid-scale energy storage technologies are gaining popularity.
Pumped hydro storage is efficient, but installations are expensive and time-consuming to build.
Lithium-ion batteries are common in small applications, but building large-scale lithium-ions remains prohibitively expensive.
Ultracapacitors and flow batteries have their niche uses.
And some cutting-edge solutions aggregate many small amounts of storage, whether from electric vehicle batters, uninterruptible power supplies, or the thermal storage embodied in water heaters.
