Hydrogen, oh! Sweet hydrogen. You abound on our planet almost as much as envy and stupidity, and there are few who know how to take full advantage of you. Hey, that’s not a joke. 75% of the total matter on our planet has hydrogen present, isn’t that amazing?
Until recently, humanity always focused on the exploitation of hydrogen in the chemical and metallurgical industry, especially as a fuel. However, understanding that this element is not found in its pure form, it is necessary to “produce” it. This is where everything gets complicated.
The reason? Simple. There are many ways to get hydrogen. However, most of them (and the most used today) have a significant natural footprint.
SO WHAT IS GREEN HYDROGEN?
A few paragraphs ago we mentioned that hydrogen cannot be obtained pure from nature, correct? Therefore, a process or mechanism was needed to manufacture it.
Green hydrogen is simply that which is obtained through processes that do not compromise our planet. That is, those that use renewable energy or production processes with little impact on nature.
Its appearance and value in the fight against climate change is key, since it implies a way of obtaining energy that is different from highly polluting fossil fuels.
HOW DOES GREEN HYDROGEN WORK?
If you already know how hydrogen works as a fuel, it will not be difficult for you to understand how green hydrogen works. In a way, the process is the same.
To convert hydrogen into energy, it needs to be stored in tanks with the capacity to channel it into fuel. There, this element is combined again with oxygen, which is obtained from air and water.
WHAT SEPARATES US FROM THIS REALITY
Until now, it seems that humanity is foolish not to completely discard the classic fuel and adopt green hydrogen systems. However, it is important to know the barriers that prevent change from being immediate and imminent.
First of all, let’s talk about what interests most of the big companies in the world: money. Money moves everything and, in this aspect, tips the balance towards gray hydrogen. Why? Simple. It is much, much cheaper to produce tukif.
However, this could change in the coming years. Let us remember that the popularization and the fall in its application price opens new windows of opportunity. A key example is solar energy, which is currently 10 times cheaper.
However, this does not imply that the investment should not be gigantic. We live in a world that is currently adapted to fossil fuel, and changing that will not be cheap. Some 300,000 million dollars are estimated in the next few years ONLY for infrastructure and research.
But is it something impossible? No. Not even crazy. With private support and the right policies, by 2050 the demand for green hydrogen is expected to multiply and equal (or exceed) gray hydrogen.
That would mean a big change for our planet, and it would help us actively fight against climate change. However, it is something that, for the time being, we must continue to wait.
