Seven-Eleven Japan Co., Ltd. and Toyota Motor Corp. will study energy conservation and carbon dioxide (CO2) emissions reduction in convenience store distribution and operation.

The two companies aim to contribute to what they say will be a low-carbon and hydrogen-based society by introducing vehicles and power generators that use hydrogen to be developed by Toyota.

The companies say that fuel cell trucks—in which the refrigeration/freezer unit and the truck itself—are powered by fuel cells, will be introduced as refrigerator/freezer trucks for stores with the goal of reducing CO2 emissions.

An energy management system, combining already-installed solar power generators will be introduced to enable greater energy conservation and CO2 emissions reduction.

Under consideration is the use of a fuel cell power generator as a power source at stores with hydrogen stations.

A stationary rechargeable battery system that uses rechargeable automobile batteries will be introduced to stores and may be used as an emergency power source during disasters, in addition to possible applications for energy conservation and CO2 emissions reduction.
