INTRODUCTION. Compressed Air Energy Storage (CAES) is a process for storing and delivering energy as electricity. A CAES facility consists of an electric generation system and an energy storage system (Figure 1). Off-peak electricity at night is stored as air pressure in a geological storage vessel.
In this paper, three-dimensional CFD numerical models have been conducted to investigate the thermodynamic performance of underground reservoirs in compressed air energy storage systems at ...
Compressed Air Energy Storage (CAES) is a promising, economic technology to compliment battery and Pumped Hydro by providing storage over a medium duration (4–12 h).

In these arrangements the water can be shifted around the three proposed reservoirs and fulfill short-term energy storage needs and long-term energy and water storage needs [44]. The SPHS arrangement presented in Fig. 3.9A consists of a small lower reservoir in the river, a large intermediate reservoir, and a small upper reservoir.
Dongjiang is Hong Kong''s major source of water. Dongjiang water first started to be supplied to Hong Kong in 1965. Today, about 70-80 per cent of water comes from Dongjiang by arrangement with the Guangdong authorities. 816 million cubic metres of Dongjiang water was imported in 2023/24. The Dongshen-Hong Kong water supply system is …
