🔥 Launched in September 2026, the Terrafer project, involving @dlr-de.bsky.social and partners, is researching seasonal high-temperature geothermal storage in natural ground at up to 400 °C – to make renewable heat available when needed, for example in winter. #SolarThermal #HeatStorage

The world’s largest #heatstorage facility is taking shape in #Vantaa just north of #Helsinki #Finland
