3 new ways to store solar energy:
As solar energy experts and researchers are trying to develop solar panels to become less expensive and make panels more effective to gather as much sunlight as possible.
It is also necessary to make a breakthrough in the ways of storing this energy so that we can get energy in the absence of the sun for as long as possible.
Here are some recent ways to shorten:
First / Flow Batteries:
The metal flow batteries, which have been in use since 1980, use vanadium ions to store electrical energy and then reuse (ie, rechargeable) is one of the most important types of flow batteries and there are also types of very high capacity and their general form are tanks Fill it with vanadium ions and increase its storage capacity. Simply increase the amount of vanadium, but unfortunately the vanadium component is not cheap.
So the researchers presented another idea. This idea is inspired by fuel cells. The fuel cells that are used in the capsules and the space shuttle to supply them with energy, which are based on the idea of taking advantage of reactions in organic compounds such as methanol and turning the chemical energy into electricity. , And the idea was whether we could recharge the fuel cells with electricity again, taking advantage of solar energy. It is known that the components of fuel cells are organic components are not expensive, so we get high storage capacity at a lower cost.
This idea has been developing since 2013 so far and has achieved amazing success as the cost of kilowatt hours is less than 1/4 cents, and this type of batteries can do more than 5000 deep discharge cycles, and in 2015 was Use of non-toxic materials. Unfortunately, I do not know whether we can find them in the markets or not, and I hope that any of our dear readers will know about this and benefit us.
II / Hydrogen:
At the University of North Carolina, Professor Tom Mayler said, "There are so many wonderful people doing great things in energy storage."
In early 2014, Tom Mayler announced another new method of storing solar energy in the form of hydrogen instead of electricity. The idea is to use water, break down the bonds between its elements to get hydrogen, then put the hydrogen in special tanks and burn it for energy.
Tom Meyler's idea does not stop there. He finds a way to reduce carbon emissions in the air by using carbon dioxide to store energy by converting it into methanol and then burning methanol as fuel to get energy from it and then reuse the resulting carbon dioxide Of the combustion process again to store energy by converting it to methanol again in a closed process, the process of converting carbon dioxide to methanol by using solar energy.
III / Salt:
Another way to store solar energy in solar thermal plants is by storing thermal energy in thermal tanks using molten salts which can store a large amount of heat energy without changing its condition. This method has become widespread and has already been implemented in a number of solar thermal power plants .
