Real applications of hydrogen
The new trend in the renewable energy sector is green hydrogen, but hydrogen is not a source of energy by itself, instead it accumulates chemical energy in its molecule and delivers it in chemical combustion or electrochemical processes. So we ask ourselves: What are real uses for hydrogen?
The most well-known use in the renewable energy sector is its capacity to store energy, which is one of its most remarkable features. Hydrogen is an ideal vector functioning as an energy storage system in isolated facilities that require long-term self-consumption systems. Its use improves the current battery facility system in several ways: It prolongs the life of the facilities, reduces the price of the photovoltaic installation and does not pollute the environment.
Hydrogen injection into the natural gas network
This process, which sounds very complicated, actually only involves mixing hydrogen with natural gas. A very useful process that helps the National Decarbonization Plan by avoiding the annual emission of 6 million tons of CO2 into the environment.
Public and private vehicle fleets
Hydrogen-powered vehicles add to the boom of electric and hybrid vehicles, which are considered 0-emission vehicles. While it is true that society has standardized electric vehicles as a sustainable alternative to diesel or gasoline, hydrogen vehicles however have a number of features that are an improvement on electric vehicles, such as, it only takes 3 to 5 minutes to refuel these vehicles.
Use in industrial processes
Hydrogen has already been used for decades in the manufacturing processes of some elements that, in themselves, are highly polluting, such as fertilizers, ammonia, steel manufacturing, fuel refining, and others.
Residential and domestic use
Hydrogen is used in high-temperature fuel cells to generate electricity and heat domestic water by replacing the consumption of natural gas.
Maritime transport, whether due to cargo or passenger transport, is among the most polluting. In this case, the use of hydrogen as a zero-emission propulsion system is particularly attractive for short to medium distance travel needs.
