Denso Hydrogen Generation Tech Claims "Thousands of kW" Potential

Japanese automotive supply giant Denso teams up with power generation company Jera to jointly develop hydrogen generation technology using waste heat.

The pair plan to solidify oxide electrolyzer cell (SOEC) technology to generate sustainable green hydrogen during tests at a Jera thermal power station.

In a company statement, Denso says hydrogen production will be “essential in addressing energy use” and envisages applying the SOEC technology to automotive fueling systems because of its advantage of “high stability and efficiency.”

Jera says it is taking on the challenge of building a hydrogen and ammonia supply chain as part of its efforts to achieve net-zero CO2 emissions from its domestic and international operations by 2050. Its efforts with internal-combustion-engine powertrains see it developing greener fuels at commercial scale.

The pair will start testing Denso’s 200 kW SOEC technology next year. Depending on the outcome, the companies aim to scale up the technology to a multi-thousand-kW level by integrating multiple SOECs.
