Hydrogen Utilization Technology

Hydrogen Energy Utilization System

Shimizu developed the hydrogen energy utilization system jointly with the National Institute of Advanced Industrial Science and Technology (AIST). The system takes surplus electricity generated by solar power and other renewable energy sources, converts it into hydrogen, and stores it. It is then utilized for power generation as needed.

For hydrogen storage, the system uses metal hydride tanks with the property of absorbing hydrogen up to 1,000 times its volume to ensure compact, safe hydrogen storage in buildings. Moreover, Shimizu Smart BEMS (Building Energy Management System) provides the technology to control the production, storage, and utilization of hydrogen, according to the status of renewable energy power generation and the demand for electricity and heat in buildings.
