Oak Ridge National Laboratory Explores Abandoned Mines in the US as Water Battery Storage
Researchers at Oak Ridge National Laboratory in Tennessee are developing models to convert abandoned coal mines into underground energy storage systems using pumped-storage hydroelectricity, a technology that moves water between reservoirs at different altitudes. This approach could enable energy storage in flat regions where traditional hydroelectricity is challenging, addressing stability and chemical erosion risks. A comprehensive techno-economic analysis is underway to assess the feasibility of these projects, which aim to support renewable energy development.

At Oak Ridge National Laboratory in Tennessee, researchers are exploring the conversion of abandoned coal mines into underground energy storage systems utilizing pumped-storage hydroelectricity. This technology, often referred to as a 'water battery,' involves moving water between reservoirs at varying altitudes.
The initiative aims to overcome geographical limitations of traditional installations, enabling energy storage in flatter areas. However, challenges such as chemical erosion and structural stability must be addressed.
Advanced modeling tools are being developed to simulate water circulation and assess chemical reactions, while a techno-economic analysis is in progress to determine project viability. If successful, this could enhance long-term electricity storage for renewable energy.
