(3) How a hydrogen society works

This zone explains the mechanisms for using hydrogen energy, from manufacturing to use.

In order to achieve hydrogen-energy society, we need to build the supply chain including production, storage, and transportation to the consumption area.

Making hydrogen

Manufacturing

There are several methods for producing hydrogen, from fossil fuels like coal, oil and natural gas, biomass like wood chips and food waste and so on. Also, it becomes usual decomposing water through electrolysis, using electricity from renewable energy like solar and wind power. Also, it is growing increasingly common to use electricity generated with renewable energy, such as solar or wind energy, to separate water and make hydrogen.

Saving and moving hydrogen

Storage and Transport

Hydrogen is stored until the time it is used.

The methods include making it compressed gas and liquid cooled to –253 °C. Then, it’s transported to the place where it will be used by appropriate form on the state.

1. Hydrogen is stored as liquid and moved using a liquid hydrogen trailer

2. Hydrogen is stored as gas and moved with a high-pressure gas trailer

Using hydrogen

Supply

Hydrogen is supplied in appropriate methods for the ultimate use.

One of them is by hydrogen station, particularly for fuel-cell vehicles. The construction is currently spreading in various areas.

Stationary Hydrogen Station

Mobile Hydrogen Station

Use

Hydrogen is used for cars like fuel-cell vehicles, also in houses through household fuel-cells and by other means. The goal for hydrogen energy is to be safely and securely utilized in various scenes of our future life.
