WHY FUEL CELLS and HYDROGEN ?
◘ Fuel cells can be thought of as alternative energy devices.
– They convert chemical energy into electrical energy.
– Hydrogen fuel cells do this very cleanly, with no toxic emissions, and with a better efficiency.
– Fuel cells do not generate energy out of thin air.
– They use hydrogen.
– Hydrogen is an outstanding carrier of energy.
◘ Hydrogen is non-toxic, renewable, easily obtained, and packed with energy.
– When it combusts with oxygen, it turns into water.
– This water can again be split into hydrogen and oxygen via electrolysis.
– The generated hydrogen can be combusted once again, thus undergoing a limitless cycle without toxic emissions.
– With a fuel cell, you can convert hydrogen into electric current without combustion.
– Fossil fuels are converted into usable energy through combustion.
◘ The energy released during combustion is inherently difficult to capture and inefficient.
– It also produces carbon dioxide, which cannot easily be converted back into a usable fuel.
– A fossil fuel combustion engine at a power plant is only about 30 to 40% efficient.
– This means it coverts only 30 to 40% of the energy in the fossil fuels to usable energy (electricity).
– Engines in a car are even less efficient, and reach the level of 15 to 20% of efficiency.
– Where does the rest of the energy go? It escapes as heat, vibration, and noise.
