Purpose / Mission

As part of the efforts to create value as a resource from non-burnable uranium (depleted uranium) available in large quantities in Japan and abroad, we will develop redox flow storage batteries that utilize uranium as an active material (URF (Uranium Redox Flow) storage batteries.) We aim to provide society with the technology through the demonstration of principles and the creation of miniature models, as well as to create the synergy between renewable and nuclear energy.

Uranium Redox Flow Storage Battery

The uranium redox flow storage battery (URF storage battery) is a storage battery that charges and discharges by facilitating the redox reaction of uranium through pump circulation.

• Large capacity30,000 kWh per URF with 650 tons of uranium (equivalent to the amount of electricity supplied to 3,000 households per day.)
• Cost-effectiveCharging and discharging occur with minimal performance degradation and no CO2 emissions.
• 100% sourced domesticallyDepleted uranium, as a raw material, can be entirely procured in Japan.
• RecyclingThe stored non-burnable uranium can be effectively utilized for electricity storage.

The URF storage battery can store surplus electricity from nuclear power plants and renewable energy sources, such as solar and wind, which helps with peak shifting and stabilizing the power grid.
