Honda to install stationary fuel cell power plant on California campus as first step toward commercializing zero-emissions backup power generation


Honda’s proof-of-concept fuel cell power plant will use fuel cell components from Honda Clarity fuel cell vehicles in a flexible quad-parallel stationary fuel cell power generation system capable of generating up to to 1152 kW-DC/1 MW-AC from an inverter. A unique advantage of the four-quad design is the ability to change the layout of the four individual fuel cell units to suit the installation environment, accepting a cuboid, L-shape, Z-shape or other packaging requirements.

The station will be connected to Honda’s US campus data center in early 2023, providing a real-world power generation application to verify performance. This will allow Honda to advance its power supply expertise, as well as supply chain development, grid connection access, construction specifications, AC connection requirements/ DC and other critical areas.

“We will leverage the expertise Honda has gained in creating several generations of fuel cell systems for the development of a fuel cell power plant, said Mitsuru Kariya, senior vice president in charge of the R&D Business Unit of the American company Honda. “This project is an opportunity to further utilize our strengths in fuel cell technology to create, evaluate and more rapidly advance a clean energy generation system for potential commercial customers.”

While Honda remains committed to developing fuel cell systems for passenger vehicles, the market for fuel cell systems to power large trucks and transport vessels, as well as stationary production, is growing rapidly in the United States. United and is expected to reach more than $86.7 billion every year by 2030. Data centers in particular require reliable, high-quality power, where any interruption in power supply can lead to downtime or issues such as data corruption and damage to servers.

Typical stationary standby generators use diesel fuel, which leads to increased carbon emissions and local air pollutants. Back-up power systems using hydrogen fuel cells offer a promising future for the production of clean, yet reliable, high-quality electricity, especially when operated with so-called “green” hydrogen made from from renewable sources, with water vapor as the only emission.

Honda Fuel Cell Technology Leadership
Honda has led the industry over the past quarter century in the development and deployment of fuel cell technology, including extensive real-world testing and customer deployments.

  • In July 2002the Honda FCX has become the first fuel cell vehicle certified by the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB).
  • In December 2002Honda introduced the world’s first production fuel cell vehicle in the United States and Japan markets.
  • In 2003, Honda became the first automaker with a fuel cell vehicle to start and operate in sub-zero temperatures.
  • In 2005, Honda became the first automaker to lease fuel cell vehicles to individuals.
  • In 2008, Honda became the first manufacturer to build and produce a dedicated fuel cell vehicle (FCX Clarity) on a production line specifically designed for fuel cell vehicles.
  • In 2013, Honda and GM began working together on the joint development of next-generation fuel cell system and hydrogen storage technologies.
  • In 2017, Honda introduced the Honda Clarity fuel cell vehicle.
  • In 2020, Honda Motor Co., Ltd. and Isuzu Motors Ltd. signed an agreement for joint research on the use of hydrogen fuel cells to power heavy-duty trucks, seeking to expand the use of fuel cells by applying zero-emissions technology to larger vehicles.
  • In 2021, Honda announced its collaboration with the Japan Aerospace Exploration Agency (JAXA) to develop a fuel cell system combined with a high differential pressure water electrolysis system that will help support a “system of circulating renewable energy” to supply space and lunar stations with electricity, oxygen and water.
  • At the FC Expo held at Japan, March 16-18, 2022Honda will show an FC power unit prototype co-developed with General Motors and a portable FC generator concept model.

Honda’s Commitment to the Environment
Honda is committed to solving global environmental and energy issues by striving to achieve carbon neutrality for all company products and operations by 2050.2 the emissions of any US automaker, according to the latest data from the US Environmental Protection Agency (EPA). To reduce CO2 Even greater emissions, Honda will strive to have battery-electric and fuel-cell vehicles account for 100% of auto sales in the United States and globally by 2040.

Honda also strives to reduce the environmental impact of its business operations. To reduce CO2 emissions from its North American manufacturing operations, Honda has entered into long-term Virtual Power Purchase Agreements (VPPAs) for renewable wind and solar power aimed at covering more than 60% of the electricity Honda uses in North America. This allows the company to fully offset the remaining carbon-intensive electricity supplied from the grid and used in its Ohio, Indianaand Alabama automotive manufacturing operations. Honda also promotes environmentally responsible business practices with its suppliers and dealer partners across North America.
