Hydrogen storage in lined caverns
The aim of this project is to further investigate the concept and design principles of storing hydrogen in lined rock caverns considering the challenges in rock mechanics.
"Hydrogen storages are predicted to play a vital role in future power and energy balancing, and in large-scale hydrogen production. Due to lack of suitable natural geological formations for hydrogen storage in Sweden, the focus is instead put on storing hydrogen in lined rock caverns (LRC) ", Ping Zhang says, Associate Professor in Mining and Rock Engineering.
A probabilistic design method will be developed through discontinuous numerical modelling technique considering the distribution of natural discontinuities and varied rock mass properties. After the model is calibrated, the optimisation of the thickness of shotcrete, concrete liner and steel lining for LRC can be reached for a future hydrogen storage plant.
The detailed objectives of the project are to: 1) investigate the LRC concept at different working conditions; 2) develop a probabilistic approach for LRC design; 3) improve design principles for LRC for hydrogen storage; 4) optimise the design parameters of LRC for hydrogen storage and 5) improve hydrogen storage as part of the fossil-free production process.
The knowledge gained from the project and the approaches/principles/guidelines developed will ultimately be applied to improve the stability of large rock caverns, long-term usage of LRC, energy efficiency of hydrogen storage and hence save cost for the industry and society.
