GEROSION EHF

Their core work

Gerosion is an Icelandic SME specializing in materials durability and corrosion protection for geothermal energy systems. They develop and test coatings, drilling components, and surface treatments that withstand the extreme temperatures and corrosive fluids found in geothermal wells. Their work spans the full geothermal value chain — from drilling technology (advanced hammers, 3D-printed sensors, coated drill pipes) to power plant operation (thermal storage, cooling systems, scaling prevention). Based in Reykjavik, they draw on Iceland's deep geothermal expertise to solve practical engineering challenges for the European geothermal sector.

What they specialise in

How they've shifted over time

Gerosion entered H2020 in 2017 with a feasibility study on metallurgical waste recycling (ALSiment), which was unrelated to geothermal energy. By 2018-2019, they pivoted entirely to geothermal applications — first coatings (Geo-Coat), then drilling (Geo-Drill), then plant operations (GeoSmart). This progression shows a deliberate move from surface-level materials science toward deep integration across the entire geothermal energy chain.

Gerosion is consolidating as a geothermal energy specialist, expanding from coatings expertise into drilling hardware and plant-level optimization — expect them to seek projects addressing next-generation geothermal systems and enhanced geothermal (EGS).

How they like to work

Gerosion primarily joins consortia as a specialist partner (3 of 4 projects), contributing materials and coatings expertise to larger teams. Their one coordination role was a small SME Instrument Phase 1 feasibility study. With 33 unique partners across 10 countries, they have built a broad European network quickly, suggesting they are a well-connected and sought-after contributor rather than a project initiator.

Gerosion has collaborated with 33 distinct partners across 10 countries, a strong network for a small Icelandic SME with only 4 projects. Their partnerships likely span geothermal-active countries in Europe (Iceland, Italy, Turkey) and research-heavy nations involved in energy R&D.

What sets them apart

Gerosion combines Icelandic geothermal field experience with advanced materials science — a combination few European SMEs can offer. Their involvement across coatings, drilling, and plant optimization means they understand geothermal systems end-to-end, not just one component. For consortium builders, they bring both practical geothermal testing environments (Iceland) and specialized coatings/materials know-how.

Highlights from their portfolio

• Geo-Drill
  Largest funding (EUR 250,938) and richest technical scope — combines graphene coatings, 3D-printed sensors, and advanced bonding for geothermal drilling innovation.
• Geo-Coat
  Their entry into geothermal R&D, focused on cost-effective corrosion-resistant coatings for high-temperature environments — directly aligned with their core competence.
• ALSiment
  Their only coordinated project and sole non-geothermal work, revealing an early circular-economy interest in transforming metallurgical hazardous waste into raw material.
