Finland traps 14 GWh of waste heat a mile underground using breakthrough tubes
SMRTR summary
Finland's Lounavoima waste-to-energy plant has implemented a groundbreaking thermal storage system using GFRP tubes to store 14 GWh of excess heat 1.2 miles underground. This innovative solution captures waste heat during summer and releases it in winter, reducing fossil fuel reliance and heating 700 homes annually. The specially designed tubes, developed through collaboration between Exel Composites and QHeat, withstand extreme underground conditions and offer improved energy efficiency, potentially reshaping energy storage and waste heat recovery.
