Outside the box... Obtain renewable energy using cans and coffee

The importance of renewable energy in human life is no longer in doubt after environmental problems have increased. We have become more in need than before of types of clean energy that preserve the environment’s resources and help humans with climate change and the effects of global warming. This strongly raises the need for usto listen to science, and to address our environmental problems with it, through unconventional ideas. Familiarity; That is why we will explore with you - in some detail - one of these ideas; So continue reading the article.

The importance of renewable energy in human life

A large percentage of the world’s population still lives on fossil fuels, which pollute the climate, deplete environmental resources, and destroy human health. That is why experts who are aware of the seriousness of what planet Earth is facing are trying to spread awareness of the importance of renewable energy everywhere, a role that Earth Guards has been playing since its founding.

If fossil energy is represented by gas, oil, and coal, then renewable energy is represented by solar energy and wind energy, as well as green hydrogen energy. This type of clean energy is low-cost, maintains health, and provides decent job opportunities.

Many of us may not realize that renewable energy sources are everywhere around us and easier to access. As we mentioned previously, they are energy derived from nature and capable of reducing carbon emissions. This is what engineers at the Massachusetts Institute of Technology thought, who came up with an “outside the box” idea that engines could be powered by environmentally friendly hydrogen fuel, by extracting it from the sea with the help of some waste and a little coffee.

A humble method and promising results

In the city of Cambridge, researchers were trying to make use of soft drink cans. They were able to extract the pure aluminum contained in these cans, then mix it with seawater, and the result was the release of hydrogen. To speed up the rate of this reaction between aluminum and seawater, these researchers added caffeine, which is found in coffee.

The researchers reported in their research published in the journalCell Reports Physical Science that they are able to produce hydrogen gas, and this is after they clean the aluminum and make it pure so that a reaction can occur between it and seawater. Then they add imidazole (colorless crystals that contain two nitrogen atoms) to accelerate the reaction, which is the substance found in Caffeine.

The question now: How does a person benefit from extracting hydrogen from the sea? Researchers believe that this new method is capable of providing ships and submarines, for example, with low-cost hydrogen energy, and in a way that can recycle waste. Here, scientists suggest that the ship carry aluminum extracted from cans - as well as other aluminum products - in addition to caffeine, and direct the hydrogen produced from these components - periodically - to the engines.

This new method will then become easier to use, especially for ships; Because there is water around it, it will not have to carry the hydrogen directly, but rather it will transport the aluminum, then add seawater to it.

The matter will not stop at developing ship energy - something that greatly supports the field of maritime shipping - but rather the new method will be useful in supplying cars with clean hydrogen energy, which is what the Massachusetts Institute of Technology team tried to implement, by developing effective and sustainable methods for producing hydrogen gas, without there being a need for a hydrogen tank in the car, but pure aluminum will be combined with water directly inside the car engine, which keeps us far from a hydrogen tank that may cause many disasters. possible; Therefore, the innovative method will be a revolutionary method in the future, as cars will become more sustainable and help recycle waste. To benefit man in many ways.

Pure Aluminum Challenge

Until this moment, the new method is considered capable of providing humans with renewable energy. However, there is a challenge that must be taken into account when implementing such a reaction, which combines seawater with aluminum and caffeine. This challenge is that the experiment requires that aluminum be at its highest level of purity, and this is the condition for it to be mixed with water.

To understand the truth of the matter, you have to imagine that when aluminum meets water with the presence of oxygen in the air, it immediately forms a thin shield of oxide that prevents the reaction from completing. This barrier is the reason why hydrogen bubbles do not appear immediately when a can of cans is dropped into the water.

The solution to this problem lies in gallium and indium (two rare metals, used in semiconductors). By using fresh water, the team found in another research that it is possible to penetrate the aluminum shield, and maintain interaction with water by treating the aluminum with a specific concentration of gallium and indium, which work to remove any accumulation of oxide, and create a surface of pure aluminum, which is free to interact with water.

Since gallium and indium are extremely rare and expensive, the team addressed this problem by recovering them back from the reaction; Thus, they can be reused without the need for other quantities.

This way we can obtain renewable energy in a sustainable manner, which is expected to benefit the areas of transportation both at sea and on land. Thus enhancing the economy and preserving the environment. It is also expected that the new method will be useful in supplying trains and airplanes with green fuel, so that the entire transportation sector will shift to renewable energy, and this may be - in the future - by extracting water from the moisture present in the air surrounding us.

The above was an idea that comes from outside the box and is capable of reducing carbon emissions. Which makes us able to combat climate change, reduce environmental degradation, and preserve our natural resources. So that our lives are sustainable.
