Honda, Tokuyama, and Mitsubishi Corporation to Conduct Joint Demonstrationof Decarbonizing Data Center Using By-product Hydrogen and Stationary FuelCell Power Station designed to Reuse Fuel Cell Systems from FCEVsTOKYO, Japan, December 25, 2023 – Honda Motor Co., Ltd. (Honda), Tokuyama Corporation(Tokuyama), and Mitsubishi Corporation (MC) (“Project Members”) will conduct a joint
demonstration to operate a data center using by-product hydrogen and a stationary fuel cell(FC) power station designed to reuse FC systems from fuel cell electric vehicles (FCEVs).
(“Demonstration Project”).
This Demonstration Project was proposed to and adopted by the New Energy and Industrial
Technology Development Organization (NEDO) as one of the projects for the “Developmentof Technologies for Realizing a Hydrogen Society / Development of Technologies for Regional
Hydrogen Utilization.”
This Demonstration Project will be conducted in Shunan City, Yamaguchi Prefecture, Japan
using by-product hydrogen produced by Tokuyama's salt water electrolysis business to supply
electricity to a distributed data center operated by MC from a stationary fuel cell power stationthat Honda will develop based on the assumption of reusing fuel cells from FCEVs.
Project Members will explore the potential of reusing automotive FC systems in a stationaryapplication. The objective of the Demonstration Project is to reduce the economic burden on
customers installing and operating stationary FC systems, which will contribute to thedecarbonization of the electric power.
A further increase in power demand for data centers is expected in the long run due to theadvancement of technologies that require large-volume data processing, such as generative
AI and automated driving. In the face of this market environment, by utilizing by-producthydrogen and FCs to power distributed data centers, the Project Members aim to facilitate thedecarbonization of data centers and the digital transformation of municipalities and localbusinesses.
Based on the knowledge gained from this Demonstration Project, the Project Members will
look into the feasibility of the installation and expansion of data centers using clean power inthe region, as well as explore further business opportunities both inside and outside Japan.

<Overview of the joint demonstration>
The official title of the Demonstration Project:
Decarbonizing data centers using by-product hydrogen and a stationary FC power station
reusing fuel cell systems from vehicle applications
Points of Demonstration:
 Verify the use of fuel cells in 1) primary and backup power sources for data centers; and2) grid-balancing (Balancing Market)
 Verify the economics and feasibility of integrated hydrogen business models operating
fuel cells and supplying hydrogen.
Demonstration period:
From the fiscal year ending March 31, 2024 through the fiscal year ending March 31, 2026.
