(INNOVATIVE WAYS TO ACCUMULATE AND PRESERVE COMPRESSED GAS ENERGY)
At present, innovative technologies for power system development and design have been given considerable attention worldwide due to the depletion of conventional energy resources and to improve their quality. One of the current lines of work in this field is accumulating energy during the non-peak period for subsequent use in case the current power demand exceeds generation. This allows for improving the economy’s sustainability and the country’s energy safety. There are various approaches to resolve this throughout the world. Promising directions include using an accumulation-and-preservation system for compressed gas energy.
The article analyzes current issues of the approach, shows some implemented project examples, and sets out the possible use of innovative solutions for accumulating and preserving compressed gas energy. These solutions have a set of advantageous features distinguishing them from prototypes: isothermal nature of the energy accumulation process, stabilized gas outlet pressure, the high power capacity of the energy storage, environmental safety, low cost price, and technical simplicity, resulting in high reliability and serviceability. A possible scheme is presented for using a compressed gas energy storage combined with a power generator working in isothermal generation mode.
The listed advantages determine the high economic indicators of introducing innovative compressed gas energy storages into power systems, including those based on renewable sources.
