Alternative Fuels | Presentation Topics | Mechanical Seminar Topics

First element in the periodic table. In normal conditions it’s a colorless, odorless and insipid gas, formed by diatomic molecules, H2. Hydrogen is the lightest and most abundant chemical element, constituting roughly 75% of the Universe’s chemical elemental mass. Non-remnant stars are mainly composed of hydrogen in its plasma state.

The interest in hydrogen as an alternative transportation fuel stems from its clean-burning qualities, its potential for domestic production, and the fuel cell vehicle’s potential for high efficiency (two to three times more efficient than gasoline vehicles). Hydrogen is considered an alternative fuel under the Energy by U.S.

Alternative fuels - hydrogen

The energy in 2.2 lb (1 kg) of hydrogen gas is about the same as the energy in 1 gallon of gasoline. A light-duty fuel cell vehicle must store 11-29 lb (5-13 kg) of hydrogen to enable an adequate driving range of 300 miles or more. Because hydrogen has a low volumetric energy density (a small amount of energy by volume compared with fuels such as gasoline), storing this much hydrogen on a vehicle using currently available technology would require a very large tank—larger than the trunk of a typical car. Advanced technologies are needed to reduce the required storage space and weight.

Huge quantities of hydrogen are used as rocket fuels, in combination with oxygen or flour, and as a rocket propellant propelled by nuclear energy.
Hydrogen can be burned in internal combustion engines. Hydrogen fuel cells are being looked into as a way to provide power and research is being conducted on hydrogen as a possible major future fuel. For instance it can be converted to and from electricity from bio-fuels, from and into natural gas and diesel fuel, theoretically with no emissions of either CO2 or toxic chemicals.

Hydrogen gas (now known to be H2) was first artificially  produced in the early 16th century, via the mixing of metals with strong acids. In 1766–81, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance, and that it produces water when burned, a property which later gave it its name, which in Greek means “water-former.”


Hydrogen can be produced from diverse domestic resources, with the potential for near-zero greenhouse gas emissions. Once produced, it generates power without exhaust emissions in fuel cells. It holds promise for economic growth in both the stationary and transportation energy sectors.


The India imports more than 90% of its petroleum, two-thirds of which is used to fuel vehicles in the form of gasoline and diesel. The demand for petroleum imports is increasing. With much of the worldwide petroleum reserves located in politically volatile countries, India is vulnerable to supply disruptions.

No matter how efficient conventional vehicles become, some of the gasoline and diesel needed to fuel them will need to be imported. Hydrogen can be produced domestically from resources such as natural gas, coal, solar energy, wind, biomass, and nuclear energy. Used to power highly efficient fuel cell vehicles, hydrogen holds the promise of an end to the nation’s “addiction to oil.”


About half of the India population lives in areas where air pollution levels are high enough to negatively impact public health or the environment. Emissions from gasoline and diesel vehicles—such as nitrogen oxides, hydrocarbons, and particulate matter—are a major source of this pollution. Hydrogen-powered fuel cell vehicles emit none of these harmful substances. Their only emission is H2O—water.

The environmental and health benefits are even greater when hydrogen is produced from low- or zero-emission sources such as solar, wind, and nuclear energy and fossil fuels with advanced emission controls and carbon sequestration. Because the transportation sector accounts for about one third of India carbon dioxide emissions, which contribute to climate change, using these sources to produce hydrogen for transportation can slash greenhouse gas emissions


The potential market for hydrogen vehicles is enormous, but the opportunities don’t stop there. Hydrogen and fuel cells can power stationary applications such as backup generators, and grid electricity production. They can also compensate for the indeterminacy of renewable energy production. For example, wind generators can produce hydrogen when winds are high and electricity demand is low. When the wind slackens or electricity demand peaks, fuel cells consume the stored hydrogen to provide grid electricity.


Hydrogen poses a number of hazards to human safety, from potential detonations and fires when mixed with air to being an asphyxiant in its pure, oxygen-free form. In addition, liquid hydrogen is a cryogenic and presents dangers (such as frostbite) associated with very cold liquids.  Hydrogen dissolves in many metals, and, in addition to leaking out, may have adverse effects on them, such as hydrogen embrittlement, leading to cracks and explosions.  Hydrogen gas leaking into external air may spontaneously ignite. Moreover, hydrogen fire, while being extremely hot, is almost invisible, and thus can lead to accidental burns.

Even interpreting the hydrogen data (including safety data) is confounded by a number of phenomena. Many physical and chemical properties of hydrogen depend on the para-hydrogen / orthohydrogen ratio (it often takes days or weeks at a given temperature to reach the equilibrium ratio, for which the data is usually given). Hydrogen detonation parameters, such as critical detonation pressure and temperature, strongly depend on the container geometry.


The simple element abundant in nature is a real alternate energy source and its potential is sensed by human kind at the right time. The application of the hydrogen is also vast. Not only that it’s eco-friendly and produces only water in form of steam during combustion which is peculiar from other energy sources. So development in hydrogen based technology will sure lead human kind to a great and wonderful future. Since our generation has the responsibility to pass the world to the next generation in sustainable form to live, hydrogen will make our responsibility possible.

    nice presentation,was just wondering,why hasnt hydrogen gas become more practical in its use as an ic engine fuel?is it only because of the storage problem,cant it be stored as compressed air?maybe using hydraulic accumulators?if hydrogen fuel can be used in automobiles it would be of great advantage…
