The armed forced of the United States are definitely working hard to reduce their dependence on conventional fossil fuel to generate energy in different locations by making use of renewable energy whenever and wherever possible. Another similar product that should reduce US Navy’s dependence on diesel fuel is being field tested by the Naval Air Warfare Center Weapons Division at China lake Naval Air Weapons Station in Ridgecrest, California.
The one-of-its-kind system features a collection of photovoltaic panels and a hydrogen fuel cell and can be easily towed behind ground vehicles to generate about 5000W of on-demand power. The self-sufficient system requires just water and sunshine to operate. The operating process is pretty simple too – sunshine is used to produce hydrogen and oxygen by electrolyzing water. Oxygen is released into the atmosphere but hydrogen is stored in tanks. During daytime, the system produces electricity using solar energy, with all excess energy being used to produce hydrogen.
After dark, hydrogen from the tanks is made to enter a fuel cell where the fuel cell generates electricity and emits water. The released water is again captured and re-used during the next day to produce more hydrogen.
