On 22 April 2026, the ATELIER project hosted the webinar “From Ground to Grid: TELUR’s Geothermal Heat Pump Journey in ATELIER”, focusing on the role of ground‑source heat pumps (GSHPs) in delivering efficient, low‑carbon heating and cooling in urban areas.
During the session, Ane Sainz‑Trapaga and Nerea San Martín from project partner TELUR presented its GSHP solution implemented in Lighthouse City Bilbao’s Zorrotzaurre Positive Energy District, where a low‑temperature geothermal loop connects different areas of the district to meet thermal demand and export surplus energy. The webinar highlighted how geothermal systems use stable underground temperatures to provide high efficiency, weather‑independent performance and very low CO₂ emissions.
Practical insights were shared on system design (closed, open and hybrid loops), real‑world performance — including seasonal performance factors (SPF) of 3–5 — and lessons learned from urban deployment. TELUR also discussed challenges such as upfront investment and showcased business models and ESCO approaches to support replication and scale‑up.
