Tokyo is working to expand demand for hydrogen energy within the city and to quickly implement it in society.
Promoting the use of hydrogen derived from renewable energy electricity (green hydrogen) is important to ensure a stable supply of energy while achieving decarbonization, and we have established a system to certify businesses that have taken the lead in the use of green hydrogen within Tokyo. We publicize these certified businesses and provide subsidies for the amount of green hydrogen they use.
We are now accepting applications for this system.

Overview of the Green Hydrogen Leading Business Certification Scheme (applications accepted from today)

Subject

Businesses that have used a certain amount of green hydrogen in the previous fiscal year within Tokyo
*This time, we will certify businesses that have a track record of use in fiscal year 2024.

Certification category	Overview	Requirements		Subsidy *Base amount: 300 yen/normal cubic meter
		Period	Usage amount
On-site type (local production for local consumption)	Generate renewable electricity and use green hydrogen at a facility within a Tokyo office	Usage record of more than 2 months per year	Usage record of more than 100 normal cubic meters per year	2/3 of the standard amount × usage amount
On-site type	Receive renewable energy electricity from other parties and produce and use green hydrogen at a facility within a business office in Tokyo			3/5 of the standard amount x usage amount
Off-site type	Procure green hydrogen produced domestically and use it at business facilities in Tokyo *Transportation using ZEV (EV or FC vehicle) *If transported by any other method, greenhouse gas emissions must be offset		Usage record of more than 500 normal cubic meters per year	1/2 of the standard amount x usage amount
(Newly constructed) Small-volume use type	Businesses that use green hydrogen produced by themselves or domestically at facilities within their business premises in Tokyo	Usage record of one month or more per year	ー	ー

Remarks

This applies to green hydrogen used by the applicant within the applicable business premises.
The certification is valid from October 1, 2025 to September 30, 2026.
(Certification is given annually based on the performance of the previous year.)
A logo mark is available for certified companies to use. Details of subsidy payment will be provided separately.

Reception period

From Wednesday, April 30, 2025 to Thursday, July 31, 2025

Key points of the FY2025 system expansion

Hydrogen ST operators added to certification list

Commercial hydrogen station operators who fill and supply green hydrogen will be added to the existing category of certification targets.
*Subsidies are not included in the payment

Establishment of a new category for “small amount of use”

A new category will be established to certify usage methods that consume less hydrogen, such as for research purposes and BCP purposes in emergencies.
*Subsidies are not included in the payment

Certification results for last year (2024)

Obayashi Corporation

Certification category

On-site type (local production for local consumption)

At the Technical Research Institute (Kiyose City), green hydrogen is produced using solar energy, and the hydrogen energy produced there is used to power facilities within the base.
By combining the results of other hydrogen projects both domestically and internationally, we aim to build a supply chain for the provision of high-quality, low-cost hydrogen.

Shimizu Corporation

Certification category

On-site type (local production for local consumption)

At Onko Soushin no Mori NOVARE (Koto Ward), we have constructed a hydrogen utilization system called “Hydro Q-BiC(R)” that produces green hydrogen using solar power, stores it inside the building in an absorbing alloy with a low risk of ignition, and optimally manages the energy within the facility, including for power supply and heat utilization.
We have begun implementing this system in multiple buildings, with the aim of further expanding its use.

This project is an initiative to promote the“Tokyo 2050 Strategy.”
