The Climate Clock Is No Longer Abstract
Climate change is often described through distant images: melting ice, future scenarios, long-term projections. But the latest indicators tell a different story. The climate signal is no longer distant. It is measurable, current and accelerating. According to the latest Indicators of Global Climate Change update, human-induced warming is now increasing at a rate of around […]

GrEnMine consortium meeting in Petroșani. Advancing gravity energy storage for post-mining regions.
The GrEnMine consortium met in Petroșani, Romania, for a project progress meeting hosted by the University of Petroșani. The meeting brought together project partners to discuss the development of gravitational energy storage technologies and their potential role in the transformation of post-mining regions. Petroșani offered a particularly meaningful setting for the discussion. As a city […]

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 […]

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.

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.
