About
Founded in 2023, TheStorage is a private headquartered in Tampere, Finland with approximately 10-50 employees specializing in Energy Storage.
TheStorage is a Finnish cleantech startup that has developed an innovative thermal energy storage solution using sand battery technology. The system converts renewable electricity into heat, stores it in ordinary sand at temperatures exceeding 1000°C in specially designed silos, and releases it on demand through a proprietary heat exchanger. The technology enables industries to decarbonize heat production by replacing fossil fuels (oil and gas) with renewable energy, while simultaneously reducing operational costs. TheStorage's sand-in-motion approach uses dynamic sand flow to achieve heat transfer efficiency 10 times greater than static storage solutions. The company operates with a team of boiler technology and steam system veterans with extensive industrial expertise. TheStorage completed its first pilot plant in Finland in 2025 and is testing the solution with industrial customers.
