Our Future with Hydrogen
Hydrogen is gaining public attention as one of the candidates for the next-generation of energy.
Environmentally friendly Hydrogen is expected to make a major contribution to sustainable societies.
Fuel Cell
A power generation device that produces electricity continuously by the chemical reaction of hydrogen with oxygen.
Fuel cell vehicles (FCVs) and Fuel cell buses use the electricity generated by fuel cells to power motors.
Residential Fuel Cell Systems
The cogeneration system that produces electricity by the chemical reaction of hydrogen reformed from fuel gases with oxygen in the air using fuel cells.
The heat generated simultaneously by the fuel cell can be used for hot water, underfloor heating, etc..
Hydrogen Engine
An internal combustion engine that uses Hydrogen as a substitute for fossil fuels. Its main emission is water vapor.
The hydrogen engine emits no carbon dioxide and is expected to be used in vehicles or aircraft.
Hydrogen fuel stations
This station is for refueling FCV or Hydrogen Engine vehicles. Produced and purified Hydrogen is compressed by the compressor and stored temporarily in a tank at high air pressure until refueling.
- Expected roles of Hydrogen -
Contribution to diversification of energy sources
Hydrogen can be produced not only from water, but also from fossil fuels such as oil, natural gas, industrial by-products, biomass and other resources.
Contribution to decarbonization
When hydrogen is burned or reacts with oxygen to produce electlicity, no CO2 is released.

Features
Hydrogen leaks and spreads easily but is difficult to detect.
The hydrogen atom (H) is the lightest atom on earth. Commonly referred to as Hydrogen, a hydrogen molecule is normally a gas with two hydrogen atoms bonded together. Because the molecular size of hydrogen is extraordinarily small, it can leak and spread very easily.
Hydrogen is a colorless and odorless gas, making it difficult for humans to detect. -
Safety hazards
More explosive than Natural gas or Propane gas
Wide explosive concentration range with the lower explosion limit at 4.0 vol% and the upper explosion limit at 75.6 vol% of hydrogen. (For more details)
The explosive concentration range of hydrogen is about four times greater than that of common combustible gases such as methane, propane, or isobutane. This is what makes hydrogen so dangerous. -
Presence
Everywhere, but Nowhere
Hydrogen is one of the most abundant elements in the universe, making up 70% of it. It is also known as the first-born atom in the universe.
Hydrogen makes up a huge part of the universe. But there are hardly any hydrogen gas molecules in the air on Earth. 99% of the air is made up of Nitrogen (78%) and Oxygen (21%). Most of the hydrogen atoms on Earth do not exist as hydrogen gas, but as an element in water, fossil fuels, organic compounds, or other chemical compounds.
Hydrogen is sometimes referred to as the ultimate energy. But it is also known as a gas with flammable and explosive properties.
To ensure safety in a hydrogen society, Figaro Engineering offers hydrogen sensors to meet a wide range of application needs.
