Polar Night Energy's Sand Battery technology stores renewable electricity as heat in sand — offering low-cost, long-duration energy storage for industrial applications. While the technology was originally developed for district heating in Finland, its potential applications extend into sectors with significant energy demands, including biotech and life sciences infrastructure.
How It Works
The Sand Battery uses excess renewable electricity to heat sand to very high temperatures. The heat is stored in an insulated steel container and can be discharged over days or weeks when needed. Unlike battery technologies that store electrical energy, the Sand Battery stores thermal energy — making it particularly suited to applications where heat, rather than electricity, is the primary requirement.
Relevance for Life Sciences
Life sciences facilities — from pharmaceutical manufacturing plants to biotech research campuses — have substantial heating and energy demands. Controlled environments, clean rooms, sterilisation processes, and laboratory equipment all require reliable energy supplies. As the industry faces increasing pressure to reduce its carbon footprint, technologies like the Sand Battery offer a pathway to decarbonising heat-intensive operations without compromising reliability.
The technology also supports district heating applications, which could benefit large research and hospital campus environments seeking to reduce emissions from their heating infrastructure.
Why we are interested: At Ayesda Bio, we track emerging technologies that could shape the infrastructure and operational landscape of the life sciences sector. Energy innovation is increasingly relevant to how our clients plan, build, and operate their facilities — and understanding these trends helps us ask better questions in our research.
