Million cubic meters from abandoned mines worldwide could be used as subsurface reservoirs for large scale energy storage systems, such as adiabatic …
This paper explores how abandoned mine voids can be utilised for this purpose comparing the technological and economical suitability of two different …
The stored energy depends on the mass of water moved and the net hydraulic head between both upper and lower reservoirs. The round trip energy …
The concept of reservoir thermal energy storage (RTES), i.e., injecting hot fluid into a subsurface reservoir and recovering the geothermal energy later, can be used to address the issue of imbalance in supply and load because of …
Exploring the development of CAES technology in underground space is one of the innovative approaches to achieve China''s "dual-carbon" goal. Underground energy …
Flooded mines constitute groundwater reservoirs that can be exploited with geothermal heat pump systems. Modelling such a reservoir is challenging because groundwater flow and heat transport equations need to be solved within the complex geometry of mine workings. To address this challenge, we developed a tridimensional …
The feasible energy storage capacity may be estimated by filtering sites below a minimum energy storage capacity and slope as in Fig. 4. For competitiveness, it is assumed that each site requires more storage capacity than a commercially available home battery (∼13.5 kWh) while accounting for its low round-trip efficiency (50%), effectively …

A deeper mine would not only produce and store more energy, but would also be more cost effective. Energy storage costs vary from $1 to $10 per kilowatt-hour for UGES, the authors calculate, downright cheap compared to lithium-ion batteries, which currently cost about $150/kWh. Battery prices continue to fall as chemistries improve, …

We discuss underground storage options suitable for CAES, including submerged bladders, underground mines, salt caverns, porous aquifers, depleted reservoirs, cased wellbores, and surface pressure ...
We assessed the potential for new pumped hydropower storage (PHS) in Europe. • Based on pairs of existing reservoirs the theoretical storage reaches 54 TWh. • Social and environmental constraints reduce the realisable potential to …
In addition, underground pumped storage hydroelectricity plants using abandoned coal mines affects carbon emissions mainly through traditional high-carbon energy sectors, such as thermal power and coal mining and selection. Therefore, the goal of carbon emission reduction can be achieved if policy-makers take into account the …

An Energy Swiss Army Knife. A mine storage supports the energy system in several ways, often simultaneously. It can act as energy storage, grid frequency regulator, capacity reserve, transmission support, inertia provider, or as a behind-the-meter solution to support large energy producers or energy-intensive industries.
Therefore, a bulk energy storage system is highly desirable to keep the surplus energy as a buffer while meeting the continuous energy demand [9]. In this context, certain sources of hydrogen qualify as a zero‑carbon energy supply, with the potential to be a viable energy vector in an eco-friendly manner [10].
