Denyo and Toyota Jointly Develop and Start Verification
Tests for Fuel Cell Power Supply Vehicle that Uses Hydrogento Generate Electricity
Environment-friendly vehicle reduces CO2 emissions, supplies continuous power for
approximately 72 hours during disasters
Toyota City, Japan, September 17, 2020―Denyo Co., Ltd. (Denyo) and Toyota Motor Corporation(Toyota) announce today that they have jointly developed a fuel cell power supply vehicle that useshydrogen to generate electricity. As a leading manufacturer of mobile (portable) generators, Denyo
will work with Toyota to start verification tests with the aim of commercializing it and to help create asustainable society, which is one of the aims of the Sustainable Development Goals (SDGs)*1. The
project has been selected by Japan’s Ministry of the Environment as a “Low Carbon Technology
Research and Development Program.”
Denyo and Toyota are both actively engaged in efforts for the global environment as they see related
problems as important issues for management. As such, they have jointly developed the fuel cell
power supply vehicle based on a belief that making efforts to apply fuel cell technologies tocommercial and industrial vehicles is needed to further reduce CO2 emissions. Together, the twocompanies have also pursued further possibilities wherein electrified vehicles, considered one
important way that they can demonstrate their belief and provide back to society, are able to provide
added value as a large-scaled power supply, delivering electricity when and where it is needed in arange of scenarios including disaster-stricken areas without power and entertainment venues suchas outdoor concerts.

Many of the current generation of power supply vehicles use diesel engines to provide power to thevehicle on the road and when generating electricity. Using fossil fuels as energy, they emit substancesof environmental concern when driving and generating electricity, including the greenhouse gases,
carbon dioxide (CO2) and nitrogen oxide (NOx). Fuel cell power supply vehicles, on the other hand,use fuel cells to provide power. This eliminates the emission of substances of environmental concern,
enables up to approximately 72 hours of continuous power supply, and provides water for showers
and other uses as a by-product of power generation.

The Toyota/Denyo fuel cell power supply vehicle that was jointly developed this time is based on
Toyota’s “Dyna” light-duty trucks, equipped with the fuel cell system of Toyota’s Mirai Fuel Cell ElectricVehicle (FCEV) as its power source. For its power supply unit, it uses a fuel cell power supply
equipment developed by Denyo under a program subsidized by the Ministry of the Environment*2. Thevehicle also carries about 65 kilograms of hydrogen (in 27 hydrogen tanks) for traveling long distancesand generating power for long periods of time.
Verification tests for the vehicle will start in September 2020. It will be compared against conventional
engine-based power generators to verify the unique characteristics of fuel cell power supply vehicles,
including their impact on various load equipment and reductions of CO2 emissions.
As a socially responsible company, Denyo is actively engaged in business activities that are inharmony with the environment, and will also continue to actively develop fuel cell-based products as
a leading manufacturer of mobile (portable) generators.
Toyota wants to dramatically reduce on-road CO2 emissions, which is one of its activities to help create
the sustainable society targeted by the SDGs. To do so, the company will continue working hard todevelop and promote the use of electrified vehicles, moving forward.
