Picea’s long-term storage capability leverages hydrogen as a seasonal energy reservoir. Unlike lithium-ion batteries, which degrade over time, hydrogen stored in metal hydride or high-pressure tanks retains energy indefinitely without efficiency loss. The system can store 1,500 kWh of energy—equivalent to 50 kg of hydrogen—sufficient to power a home for weeks during winter. Hexagon Purus supplies Type 4 high-pressure hydrogen tanks for Picea, ensuring safe and durable storage with minimal maintenance. This long-term storage addresses the fundamental challenge of balancing energy supply and demand across seasons.
