Enhancing Manufacturing Sustainability and Powering Operations through SOEC Technology

DENSO Corporation today announced its plans to launch a pilot program at the Hirose Plant, focusing on the utilization of green hydrogen produced through Solid Oxide Electrolysis Cell (SOEC) technology. The initiative aims to enhance manufacturing sustainability and power the operations of DENSO’s facility.

Driving Carbon Neutrality with Hydrogen Energy

As part of DENSO’s commitment to achieving carbon neutrality, the utilization of hydrogen energy plays a vital role. Hydrogen offers the advantage of emitting no CO2 when burned while providing significant energy. DENSO recognizes the importance of establishing a hydrogen supply chain and engages in technology development for hydrogen production, storage, transportation, and usage.

Green Hydrogen Production and Application at the Hirose Plant

The Hirose Plant, positioned as a green hydrogen utilization model factory in the semiconductor manufacturing field, will conduct a verification of green hydrogen production using SOEC technology. This verification aims to explore the feasibility of integrating green hydrogen into manufacturing processes.

Efficient Green Hydrogen Production with DENSO’s SOEC

DENSO’s SOEC device enables efficient green hydrogen production through high-temperature steam electrolysis. The device maintains a consistent high temperature of around 700°C and incorporates various technologies derived from automotive components. These technologies include thermal management techniques for temperature control, ceramic technology for efficient electrolysis at high temperatures, and ejector technology for steam recycling within the device.

Green Hydrogen Application in Prototype Power Card Line

In terms of hydrogen usage, the pilot program will include the application of green hydrogen in the prototype production line for power cards. Traditional reducing agents used in the soldering process of assembling power card components will be replaced with green hydrogen produced by the SOEC. The stability of production and the impact of green hydrogen on power card quality will be examined through this verification.

Transitioning to On-Site Green Electricity Generation

Initially, the SOEC will utilize externally purchased green electricity as its power source. However, DENSO plans to transition to on-site green electricity generated by solar power facilities installed within the Hirose Plant starting in 2025. This transition aligns with DENSO’s commitment to sustainable energy practices.

Addressing Hydrogen Transportation Challenges and Future Mass Production

DENSO aims to address the cost challenges associated with hydrogen transportation by establishing a model of local production and consumption. This involves producing green hydrogen using the SOEC within the factory and consuming it internally. Additionally, DENSO aims to leverage the expertise and technology accumulated in semiconductor manufacturing at the Hirose Plant. The knowledge gained from this verification will ultimately be applied to mass production in the future.

Contributing to a Carbon-Neutral Society through Green Hydrogen Innovation

Building upon insights and achievements from automotive product development, DENSO remains dedicated to exploring the potential of green hydrogen in the manufacturing field. By integrating expertise and technology, DENSO aims to contribute to the creation of a carbon-neutral society.
