All five H2020 projects (GECO, GeoSmart, GeoHex, SPARCs, OptiDrill) center on geothermal energy systems and operations.
ON POWER OHF
Icelandic geothermal utility providing real-world plant infrastructure, operational data, and field validation for European energy research projects.
Their core work
ON Power (a subsidiary of Reykjavik Energy) is an Icelandic geothermal energy utility that operates geothermal power plants and district heating systems in the greater Reykjavik area. In H2020 projects, they contribute real-world operational data, field testing infrastructure, and deep expertise in geothermal plant operations — from drilling and reservoir management to emission control and heat exchange optimization. Their involvement as a third party across all five projects indicates they serve as an industrial validation site, providing access to live geothermal installations where research concepts are tested under actual operating conditions.
What they specialise in
GECO project focused specifically on CO2 capture, CCS/CCU, and non-condensable gas management at geothermal sites.
GeoHex and GeoSmart both address scaling, surface engineering, ORC systems, and thermal performance in geothermal heat exchangers.
OptiDrill (2021) applies machine learning to drilling advisory systems, rate of penetration improvement, and lithology prediction.
SPARCs project involved geothermal alongside solar thermal, distributed PV, EV charging, and peer-to-peer energy transactions.
How they've shifted over time
ON Power's early H2020 involvement (2018-2019) focused on core geothermal challenges: emission control, carbon mineralisation, ORC efficiency, and scaling — the operational pain points of running geothermal plants. From 2019 onward, their scope broadened significantly into integrated energy systems (solar thermal, distributed PV, EV charging, energy communities) and data-driven operations (machine learning for drilling optimization). This trajectory shows a utility moving from purely geothermal operations toward becoming a multi-vector energy provider with digitalized operations.
ON Power is evolving from a traditional geothermal operator toward integrated smart energy and AI-assisted operations, making them increasingly relevant for projects combining renewables with digital technologies.
How they like to work
ON Power participates exclusively as a third party, meaning they provide infrastructure access, operational data, and field validation rather than leading research activities. With 90 unique partners across 19 countries, they maintain a broad European network despite their specialized role. This pattern is typical of a large utility that opens its facilities to researchers — working with them means access to real geothermal infrastructure and decades of operational knowledge.
Extensive network of 90 partners across 19 countries, built through five geothermal and energy projects. As an Icelandic utility, they bridge Nordic geothermal expertise with broader European energy research communities.
What sets them apart
Iceland is one of the few places on Earth where geothermal provides baseload electricity and district heating at scale, and ON Power operates this infrastructure daily. This gives them something most research partners cannot offer: a living laboratory for geothermal technologies under real production conditions. For any consortium needing industrial validation of geothermal concepts — from carbon mineralisation to advanced heat exchangers to drilling AI — ON Power provides the testing ground and operational reality check.
