Geothermal boost for Amsterdam: OMV and Cocreators selected to lead regional heat projects
The Aardwarmte Regio Amsterdam consortium — made up of Vattenfall, the Municipality of Amsterdam and Energie Beheer Nederland (EBN) — has selected OMV, in collaboration with Cocreators, as the operator to advance geothermal projects for collective heat networks across the Amsterdam region. The decision, reached after a European tender process, brings an experienced international energy company and a project-management specialist together with local partners to test feasibility, design potential geothermy doublets and, where viable, develop and implement geothermal heat production for district heating systems.
Why this matters
Decarbonising heating is one of the most urgent and technically complex elements of the energy transition in dense European cities. In the Netherlands, where gas has historically supplied much of the built environment, scaling low-carbon alternatives for space heating and hot water is critical to meet climate goals. Geothermal energy — heat extracted from the subsurface via production and injection wells (commonly in a doublet configuration) — offers a stable, low-carbon, large-scale heat source that can supply district heating networks year-round. For Amsterdam and the surrounding municipalities, adding geothermal capacity can reduce dependence on fossil fuels, lower greenhouse gas emissions, and strengthen the resilience of the regional heat supply.
Selection of OMV and Cocreators
OMV, an Austria-headquartered energy company with a growing portfolio in geothermal projects, won the tender as the best-placed operator in the European procurement process. Cocreators, a Dutch consultancy with direct experience in program management and delivery of urban geothermal projects (notably Geothermie Delft at the TU Delft campus), supported the bid and will remain engaged in the programme. With OMV joining the consortium as a new partner alongside Vattenfall, EBN and the City of Amsterdam, the group signed a Cooperation Agreement to investigate geothermal feasibility and — where feasible — to develop and implement geothermal doublets for the region’s heat networks.
OMV’s geothermal track record
OMV brings international project experience. Notable initiatives include “deeep,” a joint venture with Wien Energie to develop geothermal heat for Vienna, and “Tiefenkraft,” a collaboration with Energie Steiermark assessing geothermal opportunities around Graz. These projects have exposed OMV to the full lifecycle of geothermal development, from subsurface exploration and drilling operations to integration with urban heating systems and stakeholder management. This operational and technical knowledge is precisely what the Amsterdam consortium seeks: the capacity to evaluate complex geological settings, plan low-impact drilling, manage technical risks and progress projects to construction and operation where sites prove viable.
Cocreators’ local delivery experience
Cocreators contributed substantially to Geothermie Delft’s programme management, an urban geothermal plant that demonstrates how deep geothermal heat can be delivered to a university campus and integrated into existing energy systems. Their competence in stakeholder coordination, permitting processes, community engagement and urban construction logistics complements OMV’s technical strengths. Together, the partners cover both the subsurface engineering and the above-ground deployment issues that determine whether geothermal projects succeed in populated areas.
What the partnership will do first
The immediate task assigned to OMV and Cocreators is to further investigate the technical feasibility of potential geothermal locations across the Amsterdam region. This typically involves:
- Desk studies and data compilation: collecting existing geological, geophysical and hydrological information, subsurface maps, well logs and thermal gradient data.
- Surface and subsurface surveys: conducting seismic studies, magnetotelluric surveys or other geophysical investigations to characterise the subsurface and identify favourable reservoirs.
- Conceptual and numerical modelling: estimating reservoir temperature, permeability, flow rates and sustainable extraction volumes to size doublets and predict long-term performance.
- Environmental and social impact assessment: evaluating risks such as induced seismicity, groundwater interactions and surface impacts, and establishing mitigation strategies.
- Technical design and cost estimation: designing well paths, selecting drilling technologies, planning surface installations and producing capital and operating cost estimates.
- Permitting and stakeholder engagement: navigating local and national regulatory frameworks, and engaging residents, businesses and municipal authorities.
If feasibility studies are positive, the project may move into detailed design, permitting, financing and construction phases. The consortium’s stated objective includes both investigating opportunities and developing projects where appropriate, meaning some sites will progress to full development while others may be ruled out.
Geothermal in the Dutch heat mix: potential and constraints
The Netherlands has a favourable context for geothermal development in several regions due to relatively shallow sedimentary basins with high temperatures at accessible depths. Low-to-mid temperature geothermal sources are particularly useful for district heating, depending on network temperatures and heat demand density. However, successes are not guaranteed; geothermal projects involve substantial up-front costs, subsurface uncertainty and long lead times. Key considerations include:
- Geological uncertainty: Even with advanced geophysics, the subsurface can surprise developers. Reservoir permeability, temperature and connectivity determine whether a site can provide commercially viable heat flows.
- Capital intensity: Drilling deep wells and building associated surface infrastructure require significant capital investment, with costs concentrated early in the project lifecycle.
- Financing complexity: Because risks are front-loaded and returns accrue over decades, projects need tailored financing structures, public support or risk-sharing mechanisms to become bankable.
- Permitting and public acceptance: Drilling and subsurface works can raise concerns around noise, traffic, surface use and induced seismicity. Transparent engagement and robust mitigation plans are essential.
- Integration with heat networks: The value of geothermal depends on the presence of district heating systems that can absorb baseload heat; upgrading or expanding networks may be necessary to fully utilise geothermal output.
Why district heating and geothermal are complementary
District heating networks are more efficient at distributing heat at scale than individual building-level systems, especially when they serve dense urban zones or large campuses. Geothermal provides a steady, baseload heat supply that pairs well with peak-shaving technologies (e.g., heat pumps, thermal storage, or peak boilers) and renewable electricity. Combined, these systems can reduce gas consumption and provide a more predictable and controllable heat supply, which supports grid stability and decarbonisation targets.
Economic and policy implications
The selection of an experienced operator like OMV signals a step from planning to delivery-minded activity. For policymakers and municipal stakeholders, this has several implications:
- Acceleration potential: With operator expertise onboard, the pace of feasibility work and project development can increase, shortening the pathway to deployment if sites are suitable.
- Need for public support mechanisms: To attract investor capital and absorb geological risk, public instruments (grants, guarantees, concessional loans, or public–private partnerships) can be decisive. Past analyses in the Netherlands have shown that targeted financial instruments make geothermal projects more bankable.
- Skills and local supply chain development: Large geothermal projects stimulate demand for specialised drilling services, reservoir engineers and construction firms. Early and predictable project pipelines help develop local capacity and reduce costs over time.
- Regulatory clarity and coordination: Efficient permitting, clear rules on subsurface rights and coordination among agencies reduce delays and costs. The cooperation agreement signed by the four parties is an example of governance alignment at the project level.
Risks to manage
Geothermal projects in populated regions carry particular risks that the consortium must manage carefully:
- Induced seismicity: Hydraulic stimulation, common in enhancing permeability, can trigger small earthquakes. While most events are minor, they can cause alarm. Robust monitoring, conservative stimulation strategies, and compensation or mitigation frameworks are essential.
- Environmental concerns: Subsurface extraction must avoid contamination or adverse impacts on groundwater systems. Proper well integrity and monitoring are critical.
- Cost overruns and delays: Drilling can encounter technical difficulties that increase costs. Strong project and contract management, combined with risk-sharing agreements, help contain these issues.
- Market and demand risks: Heat demand projections and competing heat solutions (e.g., electrification with heat pumps, waste heat recovery) affect project economics.
Opportunities specific to Amsterdam
Amsterdam’s urban density, expanding district heating networks and climate commitments make it an attractive setting for geothermal heat if suitable reservoirs are present. Specific opportunities include:
- Supplying existing and planned heat networks with low-carbon baseload heat, thereby reducing fossil fuel backup use.
- Supporting large heat consumers — universities, hospitals, housing districts and commercial clusters — where continuous heat demand strengthens project economics.
- Using geothermal in blended systems: combining geothermal baseload with heat pumps for peak demand can optimise system efficiency and minimise electricity needs.
- Creating demonstration and learning value: Successful projects in Amsterdam would provide a blueprint for geothermal in other Dutch cities and across Europe.
Next steps and outlook
The feasibility studies that OMV and Cocreators will conduct are decisive. Over the coming months and years, these studies will either identify viable locations and move projects into development, or filter out unsuitable sites—both outcomes are valuable because they reduce uncertainty and guide investment decisions. If one or more doublets prove technically and economically viable, the consortium will face the familiar but manageable tasks of securing permits, assembling financing, contracting drilling and constructing plants and network connections.
The collaboration also demonstrates how cross-border experience (OMV) and local delivery knowledge (Cocreators) can combine to overcome the multidisciplinary challenges of urban geothermal projects. For Amsterdam, the involvement of an international operator may bring needed technical capacity and access to financing while local partners ensure the projects align with municipal goals and community needs.
Conclusion
Selecting OMV with Cocreators as operator marks a pragmatic and forward-looking step for Aardwarmte Regio Amsterdam. Geothermal is not a silver bullet, but where geology and demand align it provides a durable, low-carbon source of heat that can significantly cut emissions from the built environment. The coming feasibility phase will determine which locations are fit for development; if successful, the projects could expand and green Amsterdam’s district heating backbone. Regardless of outcomes at each site, the partnership strengthens institutional capacity, reduces technical uncertainty and advances the broader Dutch objective of a reliable, decarbonised heat supply.
