Anglesey Mining plc is considering hydro energy storage from a partner provider to support production from the underground polymetallic mine at Parys Mountain in North Wales.
NON-CAVING
A conceptual study for RheEnergise’s innovative High-Density Hydro® (HD Hydro) energy storage technology would use the former underground workings and the Morris shaft, excavated in 1989.
Anglesey said that the project fitted its own strategies for incremental investment in Parys to mitigate risks in stages before moving on to further development.
The scope of the energy storage project includes, among other stages, de-watering, refitting of the Morris shaft, upgrading of power and environmental and social studies.
The project would sell energy storage and electricity grid stability services to third parties, and potentially to the Parys mine and processing plant.
The company added it retained all options for the construction and commissioning of an underground mine.
Both companies will work on a pre-feasibility study, which will also identify potential third-party financing including from the Government.
Anglesey added that there were “value enhancing options” through planning a non-caving method of underground mining combined with the use of high-density hydro energy storage.
