According to the International Energy Agency (IEA), to meet the increasing global energy demand, storage capacity must expand to 1,500 gigawatts (GW) by 2030. It also projects that 90% of this should come from batteries alone. However, current trends in the energy storage industry are creating a different picture.
The efficiency of converting stored energy back to electricity varies across storage technologies. Additionally, PHES and batteries generally exhibit higher round-trip efficiencies, while CAES and some thermal energy storage systems have lower efficiencies due to energy losses during compression/expansion or heat transfer processes. 6.1.3.
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.
Chemical energy storage systems, such as molten salt and metal-air batteries, offer promising solutions for energy storage with unique advantages. This section explores the technical and economic schemes for these storage technologies and their potential for problem-solving applications.
