Vantaa’s Giant Underground Thermal Energy Battery
The video, describes a groundbreaking Finnish project called Vantaa, which utilizes an underground heat storage system to address the significant seasonal energy gap in northern countries. The core concept involves building massive subterranean caverns filled with water to store surplus thermal energy collected during the summer, particularly from renewable sources, and then releasing this heat for district heating during the extremely cold winter months. This geological thermal energy storage technology (CTES), which is under construction with a 2030 operational goal, is considered a strategic investment to ensure Finnish energy independence and is distinguished by its vast capacity, high operating temperature of 140°C, and significant scale, positioning it as a potentially ultimate battery solution for renewable energy challenges.
