Sekisui House, Noritz and Harman will begin joint research in November 2026 to expand the use of hydrogen energy in homes, which could help reduce household CO2 emissions. Using a newly built-in hydrogen stove, the companies will assess its effects on indoor conditions and cooking.
Sekisui House, Noritz and Harman will begin joint research to assess the potential for using hydrogen energy in homes. The research will use a household hydrogen stove that directly burns hydrogen as fuel to evaluate and examine its effects on the residential environment and its characteristics during cooking.
The testing will be conducted at the Sekisui House Comprehensive Housing Research Institute in Kizugawa, Kyoto Prefecture, where a testing environment will be established. The initiative is described as Japan’s first to target a built-in hydrogen stove for a newly built home. The companies aim to expand the use of hydrogen energy in homes as a means of reducing CO2 emissions.
Hydrogen does not emit CO2 when burned and generates a large amount of water vapour. In light of these characteristics, the companies will evaluate and analyse its effects on indoor air quality, the human body and cooking, and identify technical issues.
The research is expected to build knowledge that could support the introduction of hydrogen into homes and expand its household applications. It will begin in November 2026 and will proceed with testing focused on the household use of built-in hydrogen stoves.
