Photovoltaics on the pit and spoil tips
The basin floor, the inner slopes and the Sophienhöhe spoil tip are all usable surfaces. Three build-out scenarios, all compatible with local land-use after mining ends.
A practical concept for the Hambach basin after coal phase-out: large-scale photovoltaics, green hydrogen and heat recovery from the Niederaussem cooling loop. An open project — industry, institutions and investors are invited to shape it.
The Hambach pit does not need to stay a wound in the landscape. With the infrastructure of Niederaussem already in place, the basin can become one of Europe's most credible sites for an integrated solar, hydrogen and heat-recovery programme — something Europe genuinely needs.Wolfgang Beick · President, ITC Europe
The Hambach open-pit mine is one of the largest human-made excavations in Europe. Lignite extraction has been drawing down for years, and the nearby Niederaussem power plant is being phased out together with the rest of Germany's coal fleet. What remains is a prepared site: a basin with road and rail access, grid connections, water management and an industrial workforce ready to reskill.
The question is not whether this landscape will be redeveloped — it is what it becomes. The Hambach Energy Transition Hub is our answer: a programme that treats the pit as an asset, not a liability.
Everything the programme needs — surface area, water, grid capacity, skilled labour — is already on the ground.
Hambach is unusual: the renewable source, the conversion plant and the grid access sit within the same industrial footprint. That removes most of the cost and most of the permitting pain from an otherwise very ambitious programme.
The basin floor, the inner slopes and the Sophienhöhe spoil tip are all usable surfaces. Three build-out scenarios, all compatible with local land-use after mining ends.
The existing 22 TWh-class grid connection becomes the off-take for electrolysis. Hydrogen is stored and shipped to industrial customers in the Rhineland — chemicals, steel, mobility.
The 450 M m³/year of cooling water is currently a thermal loss. A recovery stage feeds low-grade heat into district networks and greenhouses surrounding the basin.
The numbers below assume average German irradiation of ~1,100 kWh/m²·year and the specific yield of current c-Si modules. They are order-of-magnitude guides for conversations with partners, not final engineering.
| Build-out | PV band width | Annual generation | CO₂ saved vs. lignite | Notes |
|---|---|---|---|---|
| A · Entry | 1,500 m band | ~1.1 TWh/yr | ~663,000 t/yr | Spoil-tip + inner-slope first phase |
| B · Mid | 2,000 m band | ~2.0 TWh/yr | ~1.18 M t/yr | Adds floor-level PV, partial electrolysis |
| C · Full | 2,500 m band | ~3.1 TWh/yr | ~1.84 M t/yr | Full canopy + hydrogen + heat recovery |
Chemicals, steel, glass, logistics — anyone who can absorb green hydrogen or low-carbon power at scale in the Rhineland corridor.
The Niederaussem node is one of the most powerful in Western Europe. A utility partner turns that asset into a steady renewable feed.
Federal and Länder bodies, local authorities, EU programmes. Hambach sits inside several just-transition and innovation funding streams.
Infrastructure funds, project developers and EPC contractors willing to co-lead the engineering phases alongside ITC Europe.
Module layouts designed for the slope geometry of the basin, with access corridors for maintenance and later expansion.
A 30-minute conversation to see if the scope, geography and timeline fit your organisation.
We map the parts of the programme you can lead, co-fund or off-take. Technical leads from both sides take part.
A bounded study (3–6 months) producing the numbers needed for an investment decision or a public funding bid.
If the pre-feasibility lands, the partners form a consortium to carry the engineering, permitting and financing phase.
Early technical dialogue with local stakeholders is under way. A broader consortium is the next step.
We treat every serious message as a conversation, not a pitch. Tell us briefly who you represent and what part of the programme you are curious about — we will come back with a short, specific reply.
