Researchers from Ohio University have developed an efficient way to produce hydrogen from urine. The technique could fuel vehicles while cleaning up wastewater from sewage plants.
Producing hydrogen from urine could be done at a fraction of the cost of producing it from water, as the hydrogen atoms are less tightly bound to nitrogen than they are to the oxygen atoms in water, thus taking less energy to break them apart.
However, urea quickly turns into ammonia, and produces emissions which can cause health problems such as chronic bronchitis and asthma attacks.
