Replacing fossil fuels with renewables is only the beginning. The harder task is redesigning the system around them. The energy transition is often described through objects. Solar panels. Wind turbines. Heat pumps. Electric vehicles.The more of them we install, the closer we move towards a cleaner energy system. A collection of cleaner technologies does not […]
Net zero is not one thing Climate action has developed a language problem. Emission reduction. Carbon neutral. Net zero CO₂. Net zero greenhouse gases. Climate positive. The terms are often used as if they meant the same thing. They do not. Some describe emitting less. Others describe balancing what is still emitted. Some rely on […]
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 […]
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 […]
A Structural Model for Long-Duration Energy Storage in Post-Mining Regions 1. Executive Summary Europe is accelerating its renewable energy deployment.Solar and wind are scaling faster than grid stability mechanisms. The missing layer is not generation.It is structural, long-duration storage. GrEnMine develops and validates a rail-mounted gravitational energy storage system (RM-GES) in post-mining areas, combining: Gravity […]
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 […]
A project focused on gravitational energy storage is currently underway, including the construction of a demonstrator and the assessment of the technology’s full potential. The Energy of Tomorrow – Rooted in a Mining Past Wrocław University of Science and Technology is coordinating a project that may redefine how Europe approaches energy storage. GrEnMine is an […]
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, […]
