What SCREEN Can Do for the Earth and Society
At SCREEN, we are stepping up our environmental initiatives to pursue
both the creation of cutting-edge technologies and solutions
and the establishment of a prosperous and sustainable society.
We offer solutions based on hydrogen energy, which is friendly to the environment.
What is a hydrogen society?
A hydrogen society is a society where hydrogen is used as an energy source or fuel.
It is also called a hydrogen energy society.
Hydrogen can be produced from various sources, such as water and fossil fuels including oil and natural gas, and it emits no CO2 when used.
Hydrogen has come to worldwide attention as a next-generation energy source for its potential contribution to resolving energy issues by increasing the diversity of energy sources and for its high power generation efficiency, which leads to lower energy costs.
History of energy
People have long adapted energy sources to social needs, taking advantage of technological evolution.
The scope of energy use and production has also changed dramatically, with the use of fuel cells and photovoltaic power generation spreading at an accelerated pace in recent years.
In the not-so-distant future, hydrogen is expected to become a common energy source, and SCREEN is developing and producing technologies and devices that would fit such a world.

Renewable energies
Clean energy sources already in use
Hydrogen is the most abundant and smallest molecule in the universe. It is all around us in the form of compounds such as water, methane and hydrocarbons.
Being lighter than air and able to turn into a combustible gas once a specific concentration is exceeded, hydrogen has found many industrial applications in areas such as semiconductor processing, fertilizer manufacturing and petrochemical production. More recently, new uses have emerged, such as rechargeable batteries and residential fuel cells known as Ene-Farms, currently being developed in Japan.
Hydrogen can be produced using eco-friendly energy generation methods like hydropower and wind power and be used without CO2 emissions. This makes it an ideal energy source for resource-scarce countries as well as for regions facing energy procurement issues or pursuing carbon neutrality. Expectations for the wider use of hydrogen are growing for these reasons.

Hydrogen life cycle and SCREEN’s focus
The use of hydrogen energy primarily consists of four steps. Among them, we focus on the key phases of production and use and develop technologies and components useful for these applications.
- Step 1Production
- Step 2Storage
- Step 3Transportation
- Step 4Use
