What is materials science?
The advancement of technology, facilitation of daily life, examining the properties, structures, and behaviors of materials in accordance with the needs and researching new types of materials, natural or artificial raw materials of living or lifeless origin, ceramic, polymer-like and metal engineering materials production, behavior of these materials, structure, property and workability is the branch of science.
With the advancement of material science and the emergence of new structures, the use of new technologies in energy storage has become inevitable.
In this context, there are different ideas that arise and different subjects that are tried in cooperation with materials science.
One of them is to use "Carbon Nanotube", as an energy storage unit, as a hydrogen storage unit using the cooling capabilities of "Carbon Nanotube)(CNT)".
What is materials science? What is a Carbon Nano Tube?
Nanotubes are cylindrical structures formed by carbon atoms in hegzagonal mesh consisting of crystal graphite. They exhibit superior mechanical and electrical properties.
By comparison, they are 10 times stronger and 6 times lighter than steel. Up to 3000C can continue its functionality without breaking the stable mold.
In addition, their conductivity can reach up to 1 Billion Amps/m^2. One of the best conductors, copper has 1 million Amps/m^2 conductivity.
As an issue where material science has been working extensively recently, carbon nanotubes continue to gain importance in many areas such as Ni-Co coatings and energy storage units.
What is Hydrogen Storage?
The fact that there is still no suitable method for storing large amounts of energy today further increases the importance of hydrogen.
Its storageability is perhaps the most important feature of hydrogen. It would be more appropriate to explain this with an example.
The energy produced in hydroelectric power plants or different systems must be used from the moment it is produced, so the energy produced is given directly to the lines and it is mandatory to use even if it is not needed.
Research has shown that under current conditions, hydrogen is about three times cheaper than other fuels and its use as a common energy source will depend on cost-lowering technological advances in hydrogen production.
However, storing surplus electrical energy as hydrogen is a valid alternative for today. The widespread use of energy stored in this style depends somely on the development of fuel cell-based automotive technologies.
Although hydrogen is important, its storage is a major problem.
Hydrogen somehow shows liquid properties and is as a result fixed by experimental findings that carbon can be stored in and around nanotubes.
Nanotubes activated by transition elements (Pt, Pd, Ti, V, etc.) have shown that they can be stored by absorbing hydrogen in it.
This invention is thought to use hydrogen energy, one of the energy sources of the future, to design efficient fuel cells and catalysts to be used in automobiles.
The hydrogen-cooling capabilities of carbon nanotubes are a very new issue, but research is still under way on them.
Experimental studies have indicated that they have different rates of hydrogen cooling capacities according to different pressure and temperature situations.
The process of absorbing nanotubes is due to Van Der Waal's force, which carbon atoms apply to hydrogen molecules.
So it's not a chemical, it's a physical event.
However, the high production costs of carbon nanotubes are difficult to use today.
With advances in materials science, time will tell when production will be cheaper and the future could be energy storage products.
