TELUR GEOTERMIA Y AGUA SA

Their core work

TELUR Geotermia y Agua is a Spanish private company based in Durango, Basque Country, specializing in geothermal energy systems and thermal water technologies. Their core business revolves around thermal energy storage, heat recovery from industrial processes, and ground-source thermal systems — the engineering behind capturing, storing, and redistributing heat. In their EU project work, they have contributed hands-on technical expertise in underground thermal storage, phase-change materials (PCM), and heat transfer fluids (HTF) to industrial decarbonization efforts. More recently, they have expanded their scope toward district-level energy solutions, applying their thermal systems knowledge to positive energy districts in urban settings.

What they specialise in

How they've shifted over time

In their first H2020 project (2015-2019), TELUR's focus was squarely on industrial process heat: recovering waste energy from energy-intensive manufacturing, storing it underground, and redistributing it via heat exchangers and phase-change systems. This is the engineering backbone of their geothermal and thermal water business. By 2019, their focus shifted to positive energy districts and smart city energy management — a broader, urban-scale context where thermal storage and heat recovery become components of integrated neighborhood energy systems. The trajectory suggests a deliberate move from B2B industrial clients toward city-scale infrastructure projects, likely driven by EU funding priorities and the Bilbao connection in ATELIER.

TELUR is transitioning from niche industrial heat recovery toward urban-scale energy integration, positioning themselves as a thermal systems specialist within the positive energy district and smart city ecosystem.

How they like to work

TELUR participates exclusively as a consortium partner — they have never led an H2020 project — indicating they function as a specialist technology contributor rather than a project integrator. Despite only two projects, they have engaged with 49 unique partners across 14 countries, which is unusually broad for a two-project portfolio and suggests they operate inside large, multi-partner consortia where they bring a specific technical component. This profile suits organizations who want a focused thermal systems expert who can plug into an existing consortium without needing project management overhead.

TELUR has built a surprisingly wide network for a two-project participant: 49 unique partners across 14 countries, almost certainly driven by ATELIER's large smart-city consortium spanning Amsterdam and Bilbao. Their Basque Country base gives them a natural gateway into both Spanish industrial networks and broader European energy innovation clusters.

What sets them apart

TELUR occupies a rare niche: a commercial geothermal and thermal water company that has translated real-world underground heat systems experience into EU research projects. Unlike university research groups or engineering consultancies, they bring operational know-how in geothermal infrastructure — the kind of grounded technical credibility that consortia need when moving from lab to pilot scale. Their Bilbao location also makes them a natural entry point for Basque industrial ecosystems, one of Europe's most active manufacturing and energy clusters.

Highlights from their portfolio

• ATELIER
  The largest project by EC funding (EUR 660,012) and longest duration (2019-2026), connecting Amsterdam and Bilbao in a citizen-driven positive energy district Innovation Action — TELUR's participation signals their acceptance as a thermal systems contributor in high-profile city-scale EU pilots.
• SUSPIRE
  Their foundational H2020 project, directly aligned with their core geothermal and thermal storage business, providing evidence-based credentials in underground thermal storage, PCM, and industrial waste heat recovery.
