Oxygen, nitrogen and hydrogen are essential small molecules for life, matter and energy. They embody Air Liquide's scientific territory and have been at the core of the company's activities since its creation in 1902.
Hydrogen sulfide generated from sewage sludge is a major odorous substance that causes complaints from neighboring inhabitants and health hazards of workers. In order to solve the problems, deodorizing agents are applied in many facilities.
From the viewpoint of reducing the environmental burden, hydrogen is an ideal fuel, but it is not been clear how hydrogen fuel will be developed, that is, how it will be produced, stored and transported.
Hydrogen is highly reactive, and the materials currently used to store it pose problems because it is difficult to get the hydrogen into and out of the material, and the storage material breaks down over time.
The problem is that hydrogen rarely exists in its pure form in nature, so to get H2, you have to put water through electrolysis or put natural gas through a chemical reaction such as steam reforming.
Two types of gases were used in this system, hydrogen was used as a reacting gas and the argon for flashing the air from the system, and both of them were controlled by a flow meter.
For example, knowing that the composition has four atomscarbon and ten hydrogens, we can conclude that this substance belongs to the class of saturated hydrocarbons having the general formula CnH2n+ 2.
The hydrogen sulfide that is included in the sulfur is beneficial for improved blood circulation, and at altitudes higher than 1000 meters, the heart rate goes up and the metabolism becomes energized.
The hydrogen delivers more than 2,600kWh of electricity to power the engine or recharge the batteries enabling an additional range of up to 6 days at 5 knots.
On the other hand, we can expect to reduce the sourcing and supply risks as hydrogen can be obtained from a wide variety of sources, along with greater storage and transport potential.
The hydrogen supplied for this purpose is of a natural form, which can be realized from water or the atmosphere through already established, known technologies.
The oxygen is released back into the atmosphere, while the hydrogen is set apart and transferred to a synthesis reactor where it reacts with CO2 supplied by a nearby facility.
Because the hydrogen used for the reduction is extracted from the gas released during the coking(coke production) process, this method effectively utilizes a source of hydrogen inherent to the steelmaking process.
The hydrogen for fuel cells, at least in the near term, will come ultimately from the hydrogen available in hydrocarbon sources through a process called reforming.
It is present in large amounts on the earth in the form of water(H2O), a compound of hydrogen and oxygen, and the oceans account for approximately 70% of the earth's surface.
The new hydrogen refueling station will adopt an offsite supply method using liquefied hydrogen, by which the hydrogen fuel for the station will be transported by tank trucks from the liquefied hydrogen production plant HydroEdge in Sakai-shi, Osaka Prefecture.
The hydrogen system, delivers more than 2,600 kWh of electricity to power the engine or recharge the batteries enabling an additional range of up to 6 days at 5 knots.
