Energy: Short Essay on Energy - Your Article Library.
Methanol and ethanol fuel are primary sources of energy; they are convenient fuels for storing and transporting energy. These alcohols can be used in internal combustion engines as alternative fuels. Butane has another advantage: it is the only alcohol-based motor fuel that can be transported readily by existing petroleum-product pipeline networks, instead of only by tanker trucks and railroad.
Hydrogen fuel cells were once considered the future of green energy—until research on them was squeezed out of the U.S. budget. Today, producing hydrogen is cheaper and cleaner than ever before, and fuel cells are poised for a comeback.
Hydrogen can also be used to power a fuel cell and produce electricity. This is the solution many consider to be one of the best longer-term energy sources for cars: it produces zero emissions and overcomes the limitations of onboard batteries. Currently, however, fuel cell technology remains too expensive.
The major future markets for hydrogen depend primarily upon four aspects: (1) the future cost of hydrogen, (2) the rate of advances of various technologies that use hydrogen, (3) potential long-term restrictions on greenhouse gases, and (4) the cost of competing energy systems. Hydrogen holds the promise as a dream fuel of the future with many social, economic and environmental benefits to.
In my opinion, hydrogen will be the best alternative fuel energy for automotive in future due to its low cost and zero emission.But it will need a lot of research work to get its optimal.
Hydrogen, the lightest existing molecule, is a major building block in chemistry and widely used as a raw-material by the chemical sector. It is a potent but volatile source of energy, meaning that its use and handling should be done carefully.
Electrolysis is commonly used in energy for the production of hydrogen. Electrolysis uses direct current (DC) electricity to split water into its basic elements of hydrogen and oxygen. Since this process uses only water as a source, it can produce up to 99.9995% pure hydrogen and oxygen.
