In terms of using hydrogen, LP gas, which is used in the afterburner furnace*2 to make the exhaust gases generated in the plant harmless, will be replaced by hydrogen produced in-house. Combustion of hydrogen at high temperature generates NOx gas. *3 The burner structure has been improved to achieve gentle mixing and combustion of hydrogen and air. Also the combustion temperature in the furnaces has been lowered by using combustion simulation technology refined in the manufacture of automotive component. Thereby suppressing NOx gas emissions and reducing the energy consumption are accomplished simultaneously.
In addition, in terms of transporting hydrogen, local production for local consumption of hydrogen, which aims to achieve self-consumption of hydrogen produced in-house, will help cut the transport cost, which is one of the issues in utilizing hydrogen.
Through the demonstration project, we will build a model that can optimally introduce the required amount of hydrogen according to the size of the factories by establishing a package from hydrogen production to utilization. The project aims to expand the partnership to promote the use of hydrogen in the Fukushima region, with DENSO Fukushima serving as the hub, and spread the model of local production for local consumption of hydrogen from Fukushima Prefecture to the rest of Japan.
DENSO and DENSO Fukushima will spread the use of hydrogen from Fukushima, aiming to achieve carbon neutrality at the plant and, as a model plant for carbon neutrality in the DENSO Group, accelerate the realization of carbon neutrality in the production activities of the entire DENSO Group and contribute to carbon neutral manufacturing and a carbon neutral society.
