Energy storageA fuel cell is an electrochemical energy conversion device. A fuel cell converts the chemicals hydrogen and oxygen into water and in the process produces electricity but does not store any amount of electricity except a small amount for self-activation. This method allows the excess energy formed in wind farms and solar systems to be stored and recycled/converted, instead of being left unused. Accumulating the operation of renewable power plants helps to fully exploit the return on investment and reduce the cost of electricity. Fuel cell services have energy conversion qualities that can be used voluntarily to convert chemicals into electricity when needed. Thanks to their efficiency potential, hydrogen and fuel cells are among the best solutions to meet energy demand. Used alone or in fusion systems, fuel cells guarantee medium and long-term continuity of electricity supply, even in extreme environments. This technology provides reactions to specific needs, such as stationary power supply applications. By storing hydrogen, tapping it and converting it through fuel cells, it is likely that clean energy can be provided regardless of the immediate production rate of the energy source. Preferably, additional renewable energy created during periods of sufficiency can be stored for use during periods when adequate electricity is not available, using fuel cell technology. But storing this energy is a challenging task, batteries and similar technologies work well over short periods, but over longer periods; a modified tactic is needed. Energy storage in the form of hydrogen is one such option. The extra electricity is fed into an electrolyzer to split... half the paper... systems (hydrogen and synthesis gas) and molten antimony system (molten metal), all types ultimately produce the same product, energy storage of low-value electricity at off-peak hours. There are different types of fuel cells and each fuel cell has its pros and cons, but each fuel cell allows the consumer to increase energy production during peak demand hours, increase the elasticity of the plant and store energy in an ingenious way. Since the needs of two things are met in the same period, this is not only feasible for Kuwait, but on the other hand it is also feasible for other Arab countries. Running two mechanical systems with energy generated from a competent source is very effective because it reduces all kinds of additional and maintenance costs. Therefore, fuel cells can undoubtedly be used as a source of replacement power generation in Kuwait.
