Energy Tech
Summary
Finland has taken a bold step in clean energy innovation by launching the world’s first commercial sand battery. This thermal storage system uses heated grains to retain energy for months. Unlike traditional batteries, this solution stores excess renewable electricity as heat, ideal for meeting winter heating demands in cold climates.
The sand battery is purpose-built for thermal applications, making it an ideal solution for heat-dominant energy systems. Its ability to store and release heat slowly over time aligns perfectly with Finland’s district heating networks, especially in towns actively phasing out peat and coal. This shift is crucial, considering fossil fuel plants generate nearly 40% of the world’s carbon dioxide emissions.
