Repurposing End-of-Life Mines into Energy Storage Solutions

A prominent player in electrification and automation on a global scale, has initiated a groundbreaking partnership with , a pioneering company based in the UK specializing in gravity energy storage. The collaboration aims to transform energy storage systems by harnessing end-of-life mine shafts and state-of-the-art hoist technology. This strategic alliance focuses on accelerating the development and implementation of Gravitricity’s innovative GraviStore, a cutting-edge gravity energy storage solution tailored to efficiently utilize underground shafts for energy storage and discharge purposes.

Understanding GraviStore

By amalgamating the advantages of lithium-ion batteries and pumped hydro storage, Gravitricity’s revolutionary energy storage system, GraviStore, distinguishes itself with an impressive capacity exceeding 20 MWh. This not only ensures prolonged storage capabilities but also enables swift power delivery, catering to the needs of users with network constraints, distribution networks, and significant power consumers.

Unlike conventional batteries, GraviStore boasts an extended operational lifespan spanning decades while maintaining optimal performance levels, establishing itself as a cost-effective and sustainable solution for energy storage requirements.

This collaboration holds significant promise for ABB’s clientele in the mining sector, extending beyond conventional shaft decommissioning practices. By repurposing abandoned mine shafts for energy storage, mining companies can offset decommissioning expenses while actively contributing to the shift towards eco-friendly energy practices. Furthermore, this innovative approach creates opportunities for job generation and promotes sustainability within the mining industry.

This partnership plays a pivotal role in addressing the escalating demand for energy storage solutions in an era dominated by intermittent renewable energy sources.

As the world generates more electricity from intermittent renewable energy sources, there is a growing need for technologies which can capture and store energy during periods of low demand and release it rapidly when required… Our GraviStore underground gravity energy storage uses the force of gravity to offer some of the best characteristics of lithium-ion batteries and pumped hydro storage – at low cost, and without the need for any rare earth metals.
