Anglesey Mining Announces Publication of a Conceptual Study of a
The findings of the conceptual study indicate that there is a positive business case for the project, that the risks identified thus far can be reasonably overcome or mitigated and that the project will advance the delivery of a producing underground polymetallic mine at
Background
Exploring the deployment of RheEnergise’s innovative High-Density Hydro® (HD Hydro) energy storage technology at the
Elements of the energy storage project scope, for example: the de-watering and refitting of the Morris shaft for material and personnel hoisting, the dewatering of the workings emanating from the Morris shaft 280m below the surface, the upgrading of the power-line to site, the on-going environmental and social studies and the deployment of impact avoidance, mitigation and compensation strategies, are each synergistic with the first steps of establishing a modern underground mine on
It is an essential and clear intent of this project that
The energy storage project will initially market its products, which are energy storage and electricity grid stability services, to third parties. In the future the
Pre-feasibility study
A key aspect of this study stage is to identify third party funders for the project including reviewing the range of government incentives available for R&D renewable energy storage projects, highlighting the link to the primary supply of critical minerals for the
Vision for the partnership between RheEnergise and
From the early work done by RheEnergise and
# There is an increasing justification for the deployment of on-site energy storage facilities at many mining sites. A consistent and reliable (firm) power supply is generally required not only to ensure environmental, health and safety controls continue to be in place but also importantly for processing operations, because: firstly, re-starting machinery from an unexpected power outage is usually expensive, as it is hindered by having a high tonnage of in-plant inventory, and secondly there is a financial imperative to utilize the capacity of high-cost capital equipment. # It is likely that firm power will become disproportionally more expensive if a greater share of energy generation onto the power grid is sourced from intermittent renewable technologies, such as wind and solar. # This energy storage need is juxtaposed, at a typical mine site, with at least two physically unique advantages for deploying high-density hydro power storage: firstly, the core business of underground void creation, some portion of which may be re-purposed within the mining sequence as upper and lower fluid storage reservoirs and secondly, because the on-site processing facility normally generates waste fines in the form of tailings, which through an incremental process could be incorporated into the manufacturing of the high-density fluids required.
This high-density hydro power storage project, the first commercial deployment of RheEnergise’s innovative technology, proving it at technology readiness level 8, would facilitate the practical method by which the power necessary for the mine and processing plant comes from entirely renewable energy sources, both from new and existing suppliers, on the Isle of Anglesey.
