Your idea of using underground compressed air for energy storage is intriguing and has
been implemented in various locations as Compressed Air Energy Storage (CAES). It's
great that you provided some advantages and disadvantages of this method. Here are a
few points and questions:
A. You mentioned that if there are no suitable caves, a tank can be built on the surface.
Could you elaborate on the construction process and any potential environmental impacts
associated with building these tanks on the surface?
B. Your information about CAES's power capacity, energy storage capacity, and efficiency
is helpful. Could you provide more details on the typical lifespan of CAES facilities and
how they might compare to other energy storage options in terms of cost-effectiveness
over their operational lifetimes?
C. It's good to know that CAES is considered energy-efficient and environmentally
friendly. Can you share any insights into advancements or ongoing research in this field to
overcome the challenges of site selection and construction duration?
Additionally, have you come across any notable real-world examples of successful CAES
projects or areas where CAES is particularly well-suited?
Thank you for the valuable information and references provided in your post.
