Tokyo Suiso-miru

What is the
Tokyo Hydrogen Museum (Tokyo Suiso-miru)?

Toward the realization of a carbon neutral society by 2050, hydrogen attracts attention as a decarbonized alternative energy source, along with renewable energy including solar power and hydropower.
The Tokyo Hydrogen Museum is a facility that enables children and adults alike to learn the value of hydrogen energy toward the realization of a hydrogen-based society, which is a goal of the Tokyo Metropolitan Government (TMG).

Target year 2030. First step toward decarbonization.

In 2020, Japan declared that by 2050, it aims to have achieved carbon neutrality, or to have reduced CO2 emissions to net-zero.
TMG recognized the period until 2030 as an especially important process and established two important objectives related to its hydrogen policy. The first is to expand the use of green hydrogen, and the second is the establishment of infrastructure in the transportation sector.
As the city that consumes the largest amount of energy in Japan, Tokyo has set the pace as the city with the highest demand for hydrogen energy as well as renewable energy.

The key to the use of hydrogen energy is its combined use with renewables.

In Japan, which relies heavily on fossil fuels to meet its electricity generation needs, the hardest challenge is to switch to renewable energy.
With respect to renewable energy, which is dependent on the conditions of nature, stable supply is the key issue to be solved. Thus, if surplus electricity generated by renewables can be stored in the form of hydrogen, its potential will further increase.
This is the reason why hydrogen is now attracting attention.

The hydrogen energy-based society that TMG aims at.

By 2030, TMG aims to increase the use of hydrogen in the transportation and other sectors.
It will regulate the sales of new gasoline-fueled cars and motorbikes, utilize hydrogen-fueled buses and trains, improve hydrogen stations, etc. to expand both the demand for and supply of hydrogen energy.
In addition, TMG will improve the supply system in Tokyo by importing hydrogen from overseas and building pipelines.

Promoting the installation of fuel cells that supply electricity generated by hydrogen energy.

TMG is currently focusing its efforts on the installation of fuel cells in Tokyo, both for industrial and household use, and TMG provides support for their installation.
TMG is also promoting the installation of fuel cell units with which hydrogen production facilities operated by solar power generation are established.
Visitors to the Tokyo Hydrogen Museum can see a demonstration of actual electricity supply equipment as a hydrogen-based energy management system.
