Taisei Corporation has developed a pilot project at its Zero Energy Building facility in Yokohama, Japan, which operates entirely on solar power using a hybrid storage system. The system integrates lithium-ion batteries and low-pressure hydrogen, managed by an energy management system (EMS) that balances energy supply and demand.
In June 2024, the system generated 444 kWh of electricity on a sunny day, with 57 kWh consumed directly, while 155 kWh was stored in batteries. Conversely, in February 2025, it produced 297 kWh, utilizing stored hydrogen to meet evening demand. The company aims to optimize this framework for year-round renewable operations and is engaged in broader hydrogen supply chain projects to support Japan's decarbonization efforts.
