Geothermal-Solar Hybrid Power Station GeoSolar Launches in Iceland: Achieving 24/7 100% Renewable Energy Generation

Iceland's energy company Reykjavik Geothermal announced on December 1 that the geothermal-solar hybrid power station GeoSolar has officially launched in northern Iceland. The station uses tower-based concentrated solar power during the day, with excess heat injected into underground thermal storage layers; at night, it uses the thermal storage and natural geothermal energy to maintain generation. With an installed capacity of 50 megawatts, it operates 24 hours a day without interruption.

GeoSolar's design addresses the intermittency challenge of renewable energy. The project's chief engineer said Iceland's high latitude makes winter daylight hours extremely short, but abundant geothermal resources perfectly compensate for this limitation. GeoSolar's capacity factor reaches 92%, approaching traditional thermal power station levels, offering a new paradigm for round-the-clock renewable energy supply globally.
