The technologies that are most suitable for grid-scale electricity storage are in the top right corner, with high powers and discharge times of hours or days (but not weeks or months). These are Pumped Hydropower, Hydrogen, Compressed air and Cryogenic Energy Storage (also known as ‘Liquid Air Energy Storage’ (LAES)).
Some key observations include: Energy Storage Capacity: Sensible heat storage and high-temperature TES systems generally offer higher energy storage capacities compared to latent heat-based storage and thermochemical-based energy storage technologies.
Slow, usually large capacity mechanical energy storage systems are represented by Pumped Hydro Storage (PHS) and Compressed Air Energy Storage (CAES), both mature technologies. It is based on pumping water into an uphill reservoir using off-peak electricity and later release it downhill to a lower reservoir to power a generator .
These are Pumped Hydropower, Hydrogen, Compressed air and Cryogenic Energy Storage (also known as ‘Liquid Air Energy Storage’ (LAES)). Fig. 2 Comparison of electricity storage technologies, from .
Other large-scale storage technologies, including compressed air and pumped hydro have similar round-trip efficiencies – in the region of 70%. Conclusion: A number of storage technologies such as liquid air, compressed air and pumped hydro are significantly more efficient than Green Hydrogen storage.
Mechanical energy storage systems can be distinguished in two main groups by looking at their response times, power and energy ratings as well. Slow, usually large capacity mechanical energy storage systems are represented by Pumped Hydro Storage (PHS) and Compressed Air Energy Storage (CAES), both mature technologies.
