Denyo Co., Ltd. (Head office: Chuo-ku, Tokyo; President: Shoichi Shiratori; hereinafter, "Denyo") has begun development of a dedicated hydrogen generator*1 equipped with an industrial hydrogen engine pioneered by the Kubota Corporation (Head Office: Naniwa-Ku, Osaka, Japan; President and Representative Director: Yuichi Kitao; hereinafter, “Kubota”). This research and development project strives to release this generator to the market despite the challenges arising from related laws and regulations and the preparation of hydrogen infrastructure.*1: A generator using only hydrogen as fuel to produce absolutely no CO2 emissions.
Background and Objectives
Easily portable generators are widely used to supply power on construction sites, at events and anywhere else that requires electricity. Most of the commonly used generators are generally diesel engine generators. Recognizing the world’s effort to push towards carbon neutrality, Denyo has been working to develop a hydrogen mixed combustion generator*2 and a fuel-cell portable generator*3.*2: Hydrogen mixed combustion generator use technologies to limit carbon dioxide (CO2) emissions through the combustion of hydrogen in combination with other fuels, such as diesel and city gas. *3: A fuel-cell portable generator produces electric energy through a chemical reaction between hydrogen and oxygen.
Regarding its initiatives for carbon neutrality in engines, Kubota has been researching engines for industrial machines with greater fuel efficiency and the application of carbon-free fuels such as hydrogen, bio and synthetic.
Whereas for its further decarbonization initiatives, Denyo started developing a dedicated hydrogen generator equipped with an industrial hydrogen engine pioneered by the Kubota Corporation, which eliminates CO2 emissions by using only hydrogen as a fuel. The development is making progress in a high-volume zone for portable generators by using a 45kVA diesel generator as a base. Denyo aims to release this dedicated hydrogen generator into the market early.
