Mission GrEnMine
Mission Stabilise renewable energy through gravity.Re-engineer post-mining land into energy infrastructure.Design systems that hold the line. Manifest There are landscapes shaped by extraction.And there are futures shaped by intention. We work at the intersection of both. Energy transition is accelerating.Solar rises. Wind expands.But growth without stability is risk. Renewables generate.Systems fluctuate.Grids demand balance. We do […]
Renewable Energy Needs Stabilisation. AGH Is Building the Future of Gravitational Energy Storage in the GrEnMine Project
In June 2025, solar power became the largest source of electricity in the European Union for the first time. The sun accounted for 17% of the energy mix—more than any other source [Reuters, 9 July 2025]. It is a historic milestone. But also a warning signal: the higher the share of renewables in the grid, […]
3rd GrEnMine Consortium Meeting Held in Crete
While autumn was settling across much of Europe, the GrEnMine consortium gathered in Crete for its 3rd project meeting — two days dedicated to advancing the development of gravitational energy storage in post-mine areas. The event was hosted by the Technical University of Crete (TUC), whose team provided both the venue and an inspiring academic […]
GrEnMine at the RFCS Coordinators’ Meeting in Crete
Some places carry history.Some projects know how to carry it forward. GrEnMine was presented at the recent Research Fund for Coal and Steel (RFCS) Coordinators’ Meeting hosted by the Technical University of Crete. Among numerous forward-looking initiatives shaping Europe’s industrial and energy transition, GrEnMine offered a distinct perspective: transforming post-mining landscapes into long-duration energy storage […]
Can a Mine Slope Carry 100 Tons? GrEnMine Tests the Limits
You do not simply place a 100-ton mass on the ground and hope for the best. When gravitational energy storage systems rely on controlled mass movement, the terrain becomes part of the engineering system. If gravity is the battery, the ground is the foundation. Within the GrEnMine project, comprehensive geotechnical simulations are being conducted to […]
Our Mission
Stabilise renewable energy through gravity.
Re-engineer post-mining land into energy infrastructure.
Design systems that hold the line.
There are landscapes shaped by extraction.
And there are futures shaped by intention.
We work at the intersection of both.
Testimonials
Alexandra Gkoutzou
Researcher
“Gravity-based energy storage in former mining areas represents a powerful intersection of sustainability, circular economy, and energy innovation. These systems convert industrial landscapes into renewable energy assets, offering scalable, low-impact energy storage crucial for balancing renewable grids. GrEnMine project plays the most significant role in advancing this initiative! “
Michał Twardosz
Head of Comunication
“The main objective of the GrEnMine project is to develop novel gravitational energy storage systems located in former mining areas and waste dump sites. “
Ec. Negoi Cosmin
Specialist inspector at
the City Hall of Petrila
„Jiu Valley and Rovinari coal basin are areas where mining activities are coming to an end. In this context, gravity based energy storage could repurpose the mining infrastructure, create new jobs and contribute to grid stability, supporting renewable energy adoption. It is a welcome initiative.”
Materials
GrEnMine develops and validates gravitational energy storage systems designed for former mining areas and waste dump sites.
The project combines engineering design, geotechnical assessment, and real-site validation to ensure that gravity-based storage solutions are structurally safe, scalable, and deployment-ready.
- The system stores excess renewable electricity by elevating mass and releases it through controlled descent.
- Full-scale simulations and mechanical modelling verify structural stability under static and dynamic loads.
- A demonstrator installation validates integration with existing terrain and grid infrastructure.
- A digital terrain assessment tool supports replication across European post-mining regions.
GrEnMine transforms elevation into energy infrastructure — built on calculation, not assumption.
