6 FAQs about [Air bag energy storage]

What is an energy bag?

An Energy Bag is a cable-reinforced fabric vessel that is anchored to the sea (or lake) bed at significant depths to be used for underwater compressed air energy storage. In 2011 and 2012, three prototype sub-scale Energy Bags have been tested underwater in the first such tests of their kind.

Can energy bags be used for underwater compressed air storage?

Conclusions This paper has described the design and testing of three prototype Energy Bags: cable-reinforced fabric vessels used for underwater compressed air energy storage. Firstly, two 1.8 m diameter Energy Bags were installed in a tank of fresh water and cycled 425 times.

Are energy bags a cost-effective energy storage system?

The Energy Bag was re-deployed and cycled several times, performing well after several months at sea. Backed up by computational modelling, these tests indicate that Energy Bags potentially offer cost-effective storage and supply of high-pressure air for offshore and shore-based compressed air energy storage plants. 1. Introduction

Where can compressed air energy be stored?

The number of sites available for compressed air energy storage is higher compared to those of pumped hydro [, ]. Porous rocks and cavern reservoirs are also ideal storage sites for CAES. Gas storage locations are capable of being used as sites for storage of compressed air .

Are energy bags ready for deployment?

However, as a result of the tests presented in this paper, Energy Bags are now well understood, well developed, and proven in real-world conditions, and are ready for deployment at larger scales within a pilot underwater compressed air energy storage plant.

What is compressed air energy storage?

Compressed air energy storage (CAES) is an energy storage technology whereby air is compressed to high pressures using off-peak energy and stored until such time as energy is needed from the store, at which point the air is allowed to flow out of the store and into a turbine (or any other expanding device), which drives an electric generator.
