According to Roydad Naft News Agency, green hydrogen is a new solution that plays a key role in dealing with the critical challenges of energy and global warming. Recent successes in renewable energy technology and electric vehicles have shown that policy and technology innovation have the power to create global clean energy industries.

But what is green hydrogen:
“Green hydrogen” refers to hydrogen that does not use fossil fuels during its production, and the hydrogen in water is separated from oxygen during the electrolysis process.

But like all fossil and non-fossil energy sources, this energy source also has advantages and disadvantages that we should be aware of.

First, we will discuss some of its most important positive points:

100% sustainable: green hydrogen does not emit polluting gases either during combustion or during production.

Storage: Hydrogen is easy to store, allowing it to be used later for other purposes at times other than immediately after it is produced.

Versatile: Green hydrogen can be converted into electricity or synthetic gas and used for commercial, industrial or transportation purposes.

However, green hydrogen also has negative aspects to consider:

Expensive: Energy from renewable sources, which are the key to producing green hydrogen through electrolysis, is more expensive to produce, which in turn makes hydrogen more expensive.

High energy consumption: Hydrogen production in general and green hydrogen in particular requires more energy than other fuels.

Safety issues: Hydrogen is a highly volatile and flammable element and therefore extensive HSE measures are required to prevent leaks and explosions.

Effects of green hydrogen:

Hydrogen as a fuel has become a practical reality in countries such as the United States, Russia, China, France and Germany. Some other countries, such as Japan, have gone even further and are looking to become a hydrogen economy.

Next, we examine the impact of green hydrogen on the future of the world:

Production of electricity and drinking water:

These two elements are obtained from the reaction of hydrogen and oxygen together in a fuel cell. This process has been very useful in space missions, for example, by providing water and electricity to the crew in a sustainable way.

energy saving:

Compressed hydrogen tanks are able to store energy for long periods of time and are also easier to operate than lithium-ion batteries because they are lighter.

Shipping and handling:

The great versatility of hydrogen allows it to be used in those applications where decarbonization is very difficult, such as heavy transport, aviation and maritime transport, there are currently several projects in this field. It is an implementation, such as Hycarus and Cryoplane, which is being carried out by the European Union (EU) and aims to introduce the use of hydrogen in passenger aircraft.

According to the forecast of the International Energy Agency, the production of hydrogen at the global level, which will be done using fossil fuels and renewable energy, will reach 30 million tons per year by 2030.

Although the countries of the Persian Gulf such as Saudi Arabia, Kuwait, Oman and the United Arab Emirates have started ambitious projects for hydrogen production, unfortunately, a comprehensive program related to the hydrogen industry has not yet been announced in Iran, and of course, recently the Ministry of Energy has announced that they are working to develop a national hydrogen document for approval in the government.

Considering the uncertain future of fossil fuels in the world and the thriving market of hydrogen and green hydrogen in particular, the Ministry of Petroleum and especially the National Petrochemical Company(NPC) should, by attracting domestic and foreign investors and providing the necessary incentives to the companies Petrochemical, encourage them to enter the field of hydrogen production.
