The key to using hydrogen as power is the fuel cell. A hydrogen fuel cell converts the hydrogen energy into electricity. Fuel cells can be used in cars, and to provide electricity to rural areas with no power lines. To power a car, the electricity produced from hydrogen energy flows into the battery, acting much like today''s hybrid electric cars.
About 10% of the energy is lost in this phrase. When hydrogen is converted to electricity inside the fuel cells, up to 50% of energy is lost. Although papers have shown differences in the data on the percentage decrease of energy in each phase of manufacturing, all of them agree that hydrogen is far from being efficient.
In fact, like lithium-ion batteries, hydrogen is a method for storing energy instead of generating energy.
