Eco Factor: Urine broken down into hydrogen using electrolysis.
With the dearth of low-emission fuels and the high cost of renewable energy generating system such as photovoltaic cells have tempted automobile manufacturers to look towards sources which are present in abundance. Being the most abundant in the universe, hydrogen has always fantasized car manufacturers as a green fuel which doesn’t bring any performance issues along as well. However, conventional process used to generate hydrogen from water and finally transporting it, aren’t as ecofriendly as the fuel itself is.
Researchers at the Ohio University are trying to solve the riddle by generating hydrogen from a cheap and readily available waste – urine. These researchers believe that electrolyzing urine for hydrogen is easy as compared to generating hydrogen from water as in urine, hydrogen molecules aren’t as tightly held as in water. The system breaks down urea at a voltage of just 0.37 volts, which
