New fuel for the world’s cars

Regarding the entry of hydrogen into the country’s fuel basket, Hashem Orei said: “The issue of energy transition, ie the transition from fossil fuels and the move to renewable and pollution-free fuels, is an issue that must be done. Recently, Cup 21” According to the Paris Agreement, global warming is set to be limited to 2 degrees by the end of this century, and countries around the world are preferably trying to keep it at 1.5 degrees. 1.2 degrees has risen, so more serious decisions must be made, and all this will make the revolutionary movement towards renewable energy more important, and as a result, investment in research and development of renewable energy technology will expand and hydrogen will become more important.

He added: “Hydrogen is very dependent on technology, so in this energy transition space that the world is in, it has become more important and is one of the claimants that along with wind, sun, etc. can replace fossil fuels, some to some extent hydrogen.” It is important to note that it can be an alternative, while wind and solar do not claim to be an alternative, but the point is that in terms of technology and confidence in the technology of this industry and hydrogen production, it is too early to draw definitive conclusions, in other words a new technology. Is.

“In any case, hydrogen technology is still immature, but it can be used a lot. It seems that the first place to be used publicly is in the transportation sector, but it has the capacity to be used in the electricity generation sector,” said the president of the Union of Iranian Energy Scientific Associations. And heating should be used, it has many pros and cons, and both are very sharp, some believe that this technology will come to fruition so soon and will provide good results that by the end of this decade in Europe we will see all the energy The required hydrogen will be supplied, some say it has disadvantages, for example hydrogen does not exist naturally in nature and must be produced. It is also costly and polluting, it must be pressed to be stored, and because the energy density is not high, It has to be moved, it can be transported in the form of a pipeline, but it is not painless.

He said: “It seems that the use of hydrogen in the transportation sector is ahead of the rest, it must be combined with oxygen to generate electricity, and in the process of hydrogen production we use heat and high pressure steam, the most common of which is methane gas during an industrial process.” Convert to hydrogen and carbon monoxide, meaning that in the process of producing hydrogen as a source of energy we must both consume energy and create pollution, if this is not the case with the sun, so when we look at hydrogen as a renewable fuel source We have to accept that we are looking at a longer horizon and it is not like wind and solar energy.

“We have to make sure that the use of hydrogen is economical and feasible, there are wind and solar power plants all over the world now, but hydrogen has not yet reached the maturity of technology,” said Klaus Schaefer, director of the Siemens hydrogen project, at the end of the tunnel. In the long run, when it comes to reducing fossil fuel pollution to zero, there is the potential to use hydrogen, so the fact that Siemens is using this fuel is a sign of hope.

“In any case, hydrogen technology is still immature and expensive, and as a result, it seems that we are still decades away from reaching this source of pollution-free energy, which is both practical and economical,” he said.

“Given that its technology is still in its infancy, no one can confirm or deny it, but in any case it is one of the competitors of the renewable scene, and in the path of the energy transition, hydrogen is definitely present and in transport,” said the professor of Sharif University of Technology. And shows its transportation because it has advantages, including its advantages for transportation and logistics; High efficiency, noise cancellation and long walking distance.
