Introduction

Hitachi, a leading Japanese technology and engineering company, has embarked on an innovative sustainability initiative in collaboration with Seven-Eleven Japan (SEJ). This partnership focuses on integrating advanced energy management systems and mobile energy storage solutions at SEJ's logistics center, the Chilled and Frozen Hino Center, located in Hino City, Tokyo. The primary goal of this initiative is to facilitate decarbonization and contribute to the establishment of a circular economy.

About the Battery Cube

One of the primary components of this initiative is the Battery Cube, a mobile energy storage system that utilizes repurposed batteries from electric and plug-in hybrid vehicles (EV/PHEV). The Battery Cube captures renewable energy produced by photovoltaic solar panels installed at the Chilled and Frozen Hino Center. This setup not only enhances energy efficiency but also promotes the reusability of valuable resources by employing batteries that are typically viewed as waste.

Hitachi's innovative approach also includes operational management of battery packs regardless of the vehicle model. By fusing EV battery management systems with charging and discharging controls, along with remote monitoring capabilities via the cloud, this advanced solution aims to maximize the effectiveness of used batteries, encouraging their recycling and reintegration into the energy cycle.

Energy Management System and Renewable Energy

In conjunction with the Battery Cube, Hitachi has also implemented an energy management system. This system plays a crucial role in harnessing solar-generated electricity. During daylight hours, the system stores power in the Battery Cube and later employs it for pre-cooling trucks used for SEJ store deliveries. By visualizing electricity consumption and automating the charge/discharge processes of the Battery Cube, the energy management system ensures efficient utilization of renewable energy.

Additionally, the initiative incorporates the service "Powered by Renewable Energy," developed by Hitachi in 2021. This service objectively evidences the use of renewable energy for the electric power consumed, supporting companies in their environmental endeavors and promotional initiatives while also meeting Scope 3 emissions strategies. This verification allows both Hitachi and SEJ to substantiate their commitment to sustainability and eco-friendliness.

Future Prospects

Moving forward, Hitachi is planning to establish a comprehensive recycling framework for battery packs that require maintenance within the Battery Cube. By sorting these packs and directing them to recycling facilities for reprocessing, Hitachi aims to further contribute to a circular economy. The overarching aim is to maximize resource efficiency and support a more sustainable future.

Conclusion

This collaboration between Hitachi and Seven-Eleven Japan signifies a critical step toward environmentally sustainable logistics practices. As businesses worldwide increasingly prioritize sustainability, this innovative approach to energy management and resource utilization could set a benchmark for future initiatives in various sectors. With a focus on reducing carbon footprints and fostering circular economies, this model showcases the potential of technology in driving positive environmental change.
