ABB and Gravitricity to collaborate on energy storage systems

Published by , Editor
Global Mining Review,


ABB has signed an agreement with UK-based gravity energy storage firm Gravitricity to explore how hoist expertise and technologies can accelerate the development and implementation of gravity energy storage systems in former mines.

Gravitricity has developed GraviStore, an innovative gravity energy storage system that raises and lowers heavy weights in underground shafts – to offer some of the best characteristics of lithium-ion batteries and pumped hydro storage. Future GraviStores will store more than 20 MWh, providing long-duration storage and rapid power delivery to network-constrained users and operators, distribution networks, and major power users.

Unlike batteries, the Gravitricity system can operate for decades without any reduction in performance. Gravitricity has already proven the system with a scale demonstrator and is exploring the potential to deploy their groundbreaking technology in decommissioned mines worldwide.

As a market leader for mine hoists with a large installed base of more than 1000 hoist solutions worldwide, ABB will collaborate by providing research and development, product development, and engineering teams specialising in the design, engineering, and operations of mine hoists and mechanical, electrical, and control technologies for hoisting.

“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,” said Martin Wright, Gravitricity’s co-founder and Executive Chairman. “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.

“We are already seeing significant interest from mine operators in Europe, India and Australia and this partnership with ABB – with decades of electrification and mine hoist system expertise – will help us accelerate our ambitious commercialisation plans. I am delighted we are working in tandem.”

The memorandum of understanding (MoU) agreement is an important step in ABB’s ambition to further develop its lifecycle service business by collaborating with companies providing adjacent and value-adding technologies.

“ABB has 130 years of history with mine hoists, since we first electrified one in Sweden in the 1890s, but this collaboration with Gravitricity shows how we can continue to diversify and adapt our technologies,” said Charles Bennett, Global Service Manager, Business Line Hoisting, ABB Process Industries. “We are eager to progress with our collaboration and explore the possibilities as we become part of the next generation of renewable energy storage systems and make use of mine shafts that are no longer in service.”

Gravitricity will bring specialist expertise in grid compliance and control systems and the teams will work together on feasibility studies to understand the application of existing hoisting technology in gravity energy stores. ABB will also offer mining industry consultation and work to identify suitable sites and shafts for the deployment of GraviStore.

The decommissioning of mine shafts is a costly and time-consuming process for mining companies. By repurposing disused mine shafts for energy storage, mine shafts can fill a productive function for up to 50 years beyond their original lifetime, and can mitigate decommissioning costs, while simultaneously creating new job opportunities and contributing to the green energy transition.
