“…Bags suitable for the purpose have actually been constructed already. The company Thin Red Line Aerospace has designed bags for use with constant pressure Compressed Air Energy Storage (CAES) at large ocean depths [20]. In that concept, the compressed air contains the stored energy, whereas in the concept presented here, air is only a working medium for moving water between different levels.…”

The paper presents two novel concepts of increasing the energy storage capacity at pumped storage power plants, both existing and new projects. The concepts utilize compressed air as a working medium to displace water from a volume originally not available for storage. The concepts are likely to give additional storage volume at a low cost, however, much development and many investigations are needed before the concepts can be shown to be technical and economical feasible solutions for energy storage. The concepts are disclosed so that researchers and utilities can start those investigations, hopefully helping the green transition by providing highly valuable energy storage for a future renewable energy having a much higher share of renewable energies than the current systems.

“…CAES plants of a several 100-MW class are planned in the United States, with financial support from the Department of Energy. The University of Nottingham (UK) and Thin Red Line Aerospace have also co-developed CAES with a fabric balloon-like vessel as an air reservoir, which can be installed on the seabed for offshore wind power generation [4].…”

With the increasing share of fluctuating renewable energy sources, such as wind power and solar cells, demands for energy storage and load leveling in the electric grid are expanding. For this purpose, hydroelectric and thermal power generations are used. In Germany, however, for reducing greenhouse gases, development of second-generation compressed air energy storage (CAES) has been advanced to replace thermal power generation. Another type of CAES called advanced humid air gas turbine (AHAT), which uses moist air as compressed gas, is being researched in Japan. In 2013, 40-MW integral experimental equipment was constructed and technical data are now being collected.

“…Using balloons, the need arises to have strong foundation for the balloons as they experience large buoyancy forces. Although used for a slightly different purpose (compressed air energy storage at great ocean depths), balloons of the type considered appropriate for this configuration have been made and tested in a laboratory [9]. The principle is intuitively understood and identical to the example used to prove the concept in the section above.…”

A new degree of freedom in water management is presented here. This is obtained by displacing water, and in this paper is conceptually explained by two methods: using an excavated cavern as a container for compressed air to displace water, and using inflatable balloons. The concepts might have a large impact on a variety of water management applications, ranging from mitigating discharge fluctuation in rivers to flood control, energy storage applications and disease-reduction measures. Currently at a low technological readiness level, the concepts require further research and development, but the authors see no technical challenges related to these concepts. The reader is encouraged to use the ideas within this paper to find new applications and to continue the out-of-the-box thinking initiated by the ideas presented in this paper.
