6 FAQs about [Coal mine tunnel compressed air energy storage madagascar]

Can compressed air energy storage be used in underground mine tunnels?

Compressed air energy storage (CAES) in underground mine tunnels using the technique of lined rock cavern (LRC) provides a promising solution to large-scale energy storage. A coupled thermodynamic and thermomechanical modelling for CAES in mine tunnels was implemented. Thermodynamic analysis of air during CAES operation was carried out.

How stable is a cavern from an abandoned mining tunnel?

Key parameters to the stability of the CAES cavern are identified. Compressed air energy storage (CAES) is a buffer bank for unstable new energy sources and traditional power grids. The stability of a CAES cavern is a key issue to cavern safety. However, the stability of a cavern from an abandoned mining tunnel has not been well studied.

Is abandoned mine roadway a CAES energy storage cavern?

Conclusions This study investigated the stability of an abandoned mine roadway as a CAES energy storage cavern with a numerical model. Being different from previous studies, the EDZ was partitioned into different zones according to their damage degree and a P-EDZ numerical model was established.

Can CAES be used in underground mine tunnels?

CAES in underground mine tunnels using the technique of LRC provides a promising solution for storing large amounts of energy. Although CAES in LRC tunnels has been extensively studied both theoretically and experimentally, commercial CAES facilities employing the technique of LRC were unheard of. Several theoretical issues are yet to be resolved.

Can a 3D simulation be used in underground mine tunnels?

In light of the assumptions outlined in Section 2.1, the coupled thermodynamic and thermomechanical processes for CAES in underground mine tunnels can be effectively approached using a 2D simulation scheme. However, when considering steel reinforcement, a 3D simulation scheme becomes necessary.

Can a gas storage cavern model the thermodynamic behaviour of LRCS?

Ignoring the spatial variation of temperature and pressure is commonly adopted in modelling the thermodynamic behaviour for LRCs or gas storage caverns.
