Framework Design and Energy Storage Optimal Planning of Tunnel
To realize the low-carbon transformation of tunnel power systems, this paper designs a framework for the tunnel power system and proposes an optimal method for energy storage capacity. First, the framework is proposed based on multiple power complementation and bidirectional interaction between supply and demand, and the

Energy tunnels: concept and design aspects
This type of tunnel normally has a large internal diameter in the range 10–12 m. The prevailing temperatures in the tunnel only have a limited effect on the temperature in the surrounding ground. Road tunnels can also belong to this category. Hot tunnels, on the other hand, usually show high internal temperatures.

Design issues for compressed air energy storage in sealed underground
Abstract. Compressed air energy storage (CAES) systems represent a new technology for storing very large amount of energy. A peculiarity of the systems is that gas must be stored under a high pressure ( p = 10–30 MPa). A lined rock cavern (LRC) in the form of a tunnel or shaft can be used within this pressure range.
Investigating the Effectiveness of Energy Tunnels in Cooling Underground
The long-term performance of energy tunnels for heating under and above-ground spaces has been investigated (Laloui and Loria 2019; Buhmann et al. 2016 ).
