Storage system, diversity of uses and combustion method
Hydrogen is normally a colorless, odorless and tasteless gas, consisting of diatomic molecules (H2). The hydrogen atom, H symbol, consists of a core unit of positive charge and one electron. It is one of the main elements of water and of all organic substance, and is widely distributed not only on Earth but throughout the universe. Industrialized hydrogen is needed for its use in certain sectors, where its application covers substantial industrial activities. It should be noted its application as energy vector ZERO EMISSIONS, a method to improve the environment and therefore, the health of people, through its introduction in the automotive sector and in the energy sector in general.
In this area, INDHO gathers all its efforts: the ability to produce renewable hydrogen for its later use as an automotive fuel, electric power and thermal energy and solution for the decarbonization of natural gas.
HYDROGEN AS ENERGY STORAGE SYSTEM
Types of hydrogen production
Hydrogen is a special chemical element for the energy storing, since the energy content of hydrogen has the highest energy density mass of all fuels: 120 MJ/kg.
For the production of storable and manageable hydrogen there are several technologies, such as:
Use of fossil fuels:
- Coal gasification.
- Reforming of natural gas.
- Reforming of partial oxidation of hydrocarbons.
They are cheaper but the most pollutants from fossil fuels.
Forms of hydrogen storage
Hydrogen storage as a pressurized gas
Liquid hydrogen storage
Hydrogen storage absorbed by metal hydrocarbons
Hydrogen storage absorbed on surface
VARIETY OF USES OF HYDROGEN
Hydrogen, as an energy vector, can store renewable energy and replace fossil fuels in many applications, managing to increase efficiency in the use of that energy.
HYDROGEN AS A FUEL
The fuel cell powered with hydrogen
The development of fuel cell powered with hydrogen is no longer an experimental application to become an alternative energy complement to conventional fuels. The use of hydrogen as an automotive fuel has become a reality, and is having a great interest because of its advantages; it removes external energy dependence and offers a high environmental commitment as it is a zero-emission fuel.
The modular nature of fuel cells, their easy installation, their usefulness for transportation and power generation sectors, areas where a quick response to a demand for constant energy is needed, make the use of the hydrogen technology highly attractive.
Hydrogen is the most efficient fuel since it has the highest heating value/weight relationship of all fuels. It produces double or triple energy than most of commonly used fuels, and reacts rapidly with oxygen.
Hydrogen is the cleanest fuel, because unlike fossil fuels, it does not produce harmful elements in combustion such as greenhouse gases, particles and nanoparticles in suspension. Only energy and clean water are produced when hydrogen is combined with oxygen in a fuel cell. In addition, it is a silent process. It should be noted that a hydrogen leak is immediately dispersed in the air and does not pollute neither soil nor water.
