A variable pressure water-sealed compressed air energy storage
Large-scale, long-period energy storage technologies primarily encompass compressed air energy storage (CAES), pumped hydro energy storage (PHES), and hydrogen energy storage (HES). Among these, PHES is heavily reliant on environmental factors, while HES faces limitations in large-scale application due to high costs.
