GREEN HYDROGEN: THE NEW RENEWABLE ENERGY

GREEN HYDROGEN: THE NEW RENEWABLE ENERGY


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?

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.

TREES THAT FIGHT AGAINST CLIMATE CHANGE

TREES THAT FIGHT AGAINST CLIMATE CHANGE
QUILLAY

For decades, scientists and experts in the field have warned us: we are at a point of no return regarding climate change. We push our planet Earth to its limits, and we have little time left to attack the problem before the damage is beyond repair.

Given the call for attention from the United Nations Organization in one of its latest reports from the Intergovernmental Panel on Climate Change (IPCC), very interesting proposals have begun to emerge.
One of the most striking, due to its use of natural resources and support for reforestation, is the use of trees as a tool to clean the atmosphere.

The first of our great heroes is originally from Chile and 100% natural. It turns out that, among many other species, the Quillay stands out for its ability to actively contribute to the enrichment of soils and the renewal of forests.

This endemic species of Chile is proposed as a solution to protect cultivated areas that are cleared and aggressively subjected to the action of the weather and rain.

Being a sclerophyllous Mediterranean species, it does not require the excessive irrigation that other species do, such as avocados, eucalyptus or pines.

Trees can also be very useful for other tasks besides saving water and protecting crops. Being plants that absorb carbon dioxide in large quantities during their respiration, they can become tools to minimize the damage of climate change.

The Living Carbon company is aware of this, and therefore decided to undertake a project: to create a genetically modified sub-species of hybrid poplars. And what makes them different? Its accelerated speed of reproduction and growth, in addition to faster and more efficient photosynthesis.

The idea is that they are capable of, on their own, absorbing the excessive amount of carbon dioxide in the atmosphere.

According to a report by Living Carbon, one of his modified specimens managed to accumulate 53% more mass during five months of growth. According to the company, this could translate into 27% more carbon absorption.

By 2019, the company has raised approximately $15 million, money that is expected to double the number of currently modified aspens.

Yes, we know. Perhaps the third on our list is not a tree as such, but it is giving something to talk about. They call it “M-TREE”, a revolutionary idea that was born in Misiones, Argentina; and that promises to revolutionize this province.

But what is the “M-TREE”? It started as a local project idea, which consisted of metal trees strategically distributed by the province to capture CO2 in the air and transform it into clean video porno, breathable air, recovering the oxygen within it.

Imagine it: a huge air conditioner every few kilometers, set to clean the air using turbines and filters. Sounds futuristic, right? Natalia Romero, in charge and founder of the project, began preparing it in 2014, long before the issue of climate change began to take center stage in the public arena.

SOLAR ENERGY: AN ALTERNATIVE TO CLIMATE CHANGE?

SOLAR ENERGY: AN ALTERNATIVE TO CLIMATE CHANGE?

Every morning, when you leave home and look up at the sky, you inevitably find it: there it is once again, our faithful and giant sun. An imposing and very powerful celestial body, whose rays provide us with one of the most powerful sources of renewable energy.

Solar energy reaches the Earth’s surface in the form of electromagnetic radiation to be captured and stored by solar panel systems. Although currently its use is not comparable to that of fossil fuels, many consider that this form of energy could be the key to saving our planet from climate change.

SOLAR ENERGY AS AN ECO FRIENDLY ALTERNATIVE

Let us remember that, as is the case with most alternative energy sources proposed as a way to combat climate change, solar energy is a renewable resource. What does this mean? Unlike fossil fuels and other polluting energy sources, solar energy does not depend on a finite resource whose extraction process is aggressive with our porno planet.

On the contrary, solar energy is used in a clean and efficient way, without producing gases that promote the “Greenhouse Effect”. Therefore, it does not contribute in any way to global warming.

This form of energy also does not emit toxic substances into the air, water or environment, avoiding the acidification of terrestrial and aquatic ecosystems that trigger heart, respiratory or cancer diseases. This is especially valuable today, when we see that little by little the natural resources for survival begin to diminish in some countries.

SOLAR ENERGY AS AN ECO FRIENDLY ALTERNATIVE

All this without mentioning that, in addition to being good for the environment, it is good for large companies and the economy. After all, within the group of alternative energy sources, this is among the cheapest to implement at the home and corporate level.

WHAT ARE THE LIMITATIONS AND OBSTACLES?

Not everything that shines like the sun is really gold. As expected, solar energy also has its obstacles and limitations in mass application.

One of the first limitations is the initial cost. Yes, it is true, in the medium or long term it may be a profitable and low-cost investment compared to other renewable energies. However, this does not mean that its cost is not high, especially in its initial phase.

Let us remember that, after all, to be able to capture and store solar energy, it is essential to have solar panels installed by professionals. These panels also require a lot of space to accumulate a significant amount of energy, capable of satisfying the needs of the communities.

Also, let’s take into account that the sun only visits us during the day, and its intensity and exposure fluctuates with the passing of the hours. All this without taking into account how excessive heat, humidity or cloudy periods affect its performance.

So, solar energy may not be the ideal ally? At least it is when we think about what we have available. What do you consider to be the most efficient alternative energy source that exists?
