Sekisui House, Noritz and Harman will begin joint research in November 2026 to evaluate residential environments using residential hydrogen stoves. The study will examine effects on indoor environments and cooking, among other factors, and explore the feasibility of installing built-in hydrogen stoves in homes.
The 3 companies will begin joint research to evaluate residential environments using hydrogen stoves, with the aim of expanding the use of hydrogen energy to help reduce CO₂ emissions in homes. The study will use residential hydrogen stoves fueled by hydrogen to assess their effects on indoor environments and cooking, as well as the feasibility of adoption.
The testing environment will be established at Sekisui House's Comprehensive Housing Research Institute in Kizugawa, Kyoto. The study will combine Noritz's and Harman's expertise in hydrogen combustion technology and equipment development.
Hydrogen does not emit CO₂ when burned and is said to generate large amounts of water vapor. The study will evaluate and analyze its effects on indoor air quality and human health, while also considering the creation of distinctive value in cooking.
The companies also plan to examine the use of hydrogen in homes, including for water heating, with the aim of creating new value in housing through evaluations of its effects on residential environments.
In this joint research, Sekisui House will establish the testing environment and evaluate the effects on residential environments, Noritz will assess heating characteristics and create new value in cooking, and Harman will be responsible for development and provision, as well as safety support.
