Device developed to hoard Solar Energy, operate Hydrogen fuel Cell cars
A device is developed by a research team that can utilize solar energy to reasonably and efficiently generate and accumulate energy, which can be utilized to power electronic devices and to produces hydrogen fuel for the eco-friendly vehicles. Hydrogen cars can be made more affordable by the device for several customers as it generates hydrogen from cobalt, nickel, and iron—components that are much more plentiful and less costly than the platinum and other valuable metals that are at present used to generate hydrogen fuel.
Professor at the UCLA (University of California, Los Angeles), the United States, Richard Kaner, said, “For vehicles, hydrogen is a good fuel. It is the cleanest recognized fuel, it is less costly, and it does not release any contaminants into the air—only water. And this can plummet the price of hydrogen cars dramatically.” The technology can be, in particular, helpful in rural regions or to military units located in remote areas.
Kaner said, “Individuals require electricity to operate their devices and fuel to operate their vehicles. Now, it is possible to produce fuel and electricity with one device.” It can also be a section of a solution for huge cities that require means to store additional electrical energy from their electrical grids, according to the scientists. He added, “If you can transform electrical energy to hydrogen, you can stock it up indefinitely.”
Conventional supercapacitors and hydrogen fuel cells have 2 electrodes: 1 negative and 1 positive. A third electrode within the device functions as both a device for splitting water into oxygen and hydrogen, a procedure known as water electrolysis as well as a supercapacitor that stores energy. All 3 electrodes unite to a single solar cell that functions as the power source of the device and the electrical energy produced by the solar cell can be stocked up in 1 of 2 means: chemically as hydrogen or electrochemically within the supercapacitor.
Also, the device is a breakthrough as it generates hydrogen fuel in an environmentally friendly manner. At present, around 95% of hydrogen generation globally comes from transforming fossil fuels, for example, natural gas into hydrogen—a method that liberates huge amounts of carbon dioxide into the air, as per the co-author of the study, Maher El-Kady.
El-Kady said, “Hydrogen power is not ‘green’ if it is generated from renewable resources.” He further said that using solar cells and plentifully obtainable elements to divide water into oxygen and hydrogen has huge prospective for decreasing the price of hydrogen generation and that the advance can ultimately substitute the existing techniques that depend on fossil fuels.
