Geological Survey of Denmark and Greenland

Their core work

GEUS is Denmark's national geological survey, providing scientific expertise on subsurface resources, groundwater, raw materials, and climate-related geoscience. They map and monitor geological conditions across Denmark and Greenland, supporting policy decisions on energy resources, water protection, mineral supply, and carbon storage. Their work spans from Arctic environmental observation to European-scale geological data infrastructure, making them a key knowledge institution for subsurface energy transition and resource security.

What they specialise in

How they've shifted over time

In the early H2020 period (2015–2018), GEUS focused on Arctic observation systems, CO2 geological storage field experiments, shale gas environmental impact, and coastal water solutions — largely oriented toward environmental monitoring and fossil fuel transition. From 2019 onward, their work shifted decisively toward critical raw materials data collection, hydrogen underground storage, electrochemical CO2 capture in industrial clusters, and climate proxy research using sedimentary DNA. This evolution reflects a clear pivot from characterising subsurface risks to actively enabling the energy transition and circular economy through geological services.

GEUS is positioning itself as Europe's go-to geological partner for underground hydrogen storage, CO2 utilisation clusters, and critical raw materials security — all top EU Green Deal priorities.

How they like to work

GEUS operates predominantly as a trusted specialist partner, participating in 18 of 25 projects versus coordinating only 4. Their 400 unique consortium partners across 46 countries indicate they are a highly networked hub rather than a repeat-partner loyalist. They thrive in large Research and Innovation Actions (11 RIA projects) and Coordination and Support Actions (7 CSA), contributing domain-specific geological expertise to broad European consortia rather than leading them.

With 400 unique consortium partners spanning 46 countries, GEUS maintains one of the widest collaboration networks among European geological surveys. Their partnerships extend well beyond Nordic and Western European institutions to include global Arctic research networks and pan-European raw materials expert groups.

What sets them apart

GEUS combines two rare capabilities: deep subsurface expertise (storage, aquifers, reservoirs) with operational field experience in extreme Arctic environments, including Greenland. Unlike university research groups, they function as a national geological service with regulatory-grade data and long-term monitoring infrastructure. For consortium builders, they bring both scientific credibility and practical geological survey capacity that can ground-truth models against real field conditions.

Highlights from their portfolio

• GeoERA
  Largest single EU funding (EUR 1.16M) — a flagship project establishing the European Geological Surveys Research Area covering geo-energy, raw materials, and groundwater across the continent.
• ICEPRINT
  Coordinated project combining sea ice biology with ancient DNA techniques as climate proxies — an unusual interdisciplinary angle for a geological survey.
• ConsenCUS
  Their most recent large project (EUR 621K, running to 2025) on industrial CO2 capture and utilisation clusters in cement, magnesia, and oil refinery sectors — directly at the energy transition frontier.
