Sample Essay on Fuel-Cell Vehicles Preferred to Conventional Ones

It is indisputable that technology has today become the greatest agent of change in the world. Despite the associated detrimental impacts, valuable technological breakthroughs offer remedies to various challenges experienced throughout the world. The recent invention of fuel-cell vehicles (FCVs) is a good example. They appear similar to the conventional vehicles but incorporate cutting-edge technology to produce energy (electricity generated from hydrogen gas). Therefore, the main issue here regards the efficiency and climate concern the development of FCVs would bring. After analyzing the working of FCVs, I support the statement that; Fuel cell vehicles are more efficient and environmentally safe than any of the existing conventional vehicles in the market.

Developers of fuel-cell vehicles say that they have the capability to decrease human reliance on imported oil effectively. In addition, it reduces to a great extent the level of dangerous emissions which have resulted in global climate change. It is because FCVs run on hydrogen gas which is converted into electricity. Therefore, the dependence on gasoline that emits harmful emissions to the atmosphere would significantly decrease. The technology would begin to reach the point where automotive industries launch it in the market. During the launching process, the highest prices go up to seventy thousand U.S dollars. However, the price is anticipated to decrease as their supply increases in the subsequent years.

Fuel-cell vehicles are distinguishable from conventional vehicles because of their high-output battery which stores energy generated from the regenerative breaking. The energy is meant to serve as a supplement providing power to the electric motor. There is a component which propels vehicle quite efficiently. Fuel-cell vehicles do not require the internal combustion engine which is used by conventional vehicles. Thirdly, there is a part that controls the flow of the electricity generated from the hydrogen gas. The last and the main feature in FCVs is the fuel cell stack which turns hydrogen gas into electricity. All these features make fuel-cell vehicles more efficient and cost-effective to operate than most current conventional vehicles.

Conventional vehicles use batteries that have to be charged with the help of an external source. It takes quite a long time of about five to twelve hours based on the vehicle and the charger used. However, the production of electricity utilizes utilizing hydrogen gas stored onboard with oxygen from the air. Practically, batteries and fuel cells are attached to fuel cells producing electricity while batteries store it until it is required by electric motors that power the vehicle. As a result, fuel-cell vehicles are hybrid and apply the regenerating braking system. The system is meant to recover energy in the wasted heat which is the reason these vehicles show great ability to maximize efficiency and range as desired by consumers.

Apart from the high efficiency attributed to fuel-cell vehicles, they are believed to be environmentally friendly. For example, these vehicles do not release dangerous emissions that have significantly contributed to the global climate change. Hydrogen gas burns smoothly, and it is clean. It produces only water in the form of vapour as waste. Therefore, fuel cell vehicles using hydrogen gas as their source of fuel do not release harmful gases into the atmosphere. It is the most important factor since this reduces environmental pollution (air pollution). Also, unlike conventional vehicles are driven by electricity generated from batteries, fuel-cell vehicles that use compressed hydrogen have a long cruising of up to six hundred and fifty miles for each tank.

There is also an argument that points to the difficulty of producing a pure hydrogen gas that fuel-cell vehicles need to generate electricity. These vehicles only utilize hydrogen gas which is clean-burning fuel yielding water as the only by-product when it is burnt in oxygen. However, pure hydrogen gas is hardly harvested by simply drilling the ground. It has to be generated from other sources which are most likely to be a fossil fuel. Fossil fuel contains carbon, and thus hydrogen gas produced when combusted in oxygen would emit carbon dioxide which causes global warming. Therefore, it is argued that; like the conventional vehicles, fuel-cell vehicles would still result in global warming.

In a way to dispel the claim that the production of pure hydrogen gas is difficult, there are various alternative methods used to generate the gas without carbon being released into the atmosphere. The common method involves the use of renewable sources of electricity. For example, there is electricity produced from wind and solar which can be used to electrolyze water. Also, hydrogen gas can also be obtained by splitting water in high-temperature nuclear reactors. The resulting element of carbon can be captured and isolated without releasing into the atmosphere. The argument which states the difficulty in producing pure hydrogen gas is, therefore, rendered baseless.

In conclusion, it is important to note that the mass-marketing of fuel-cell vehicles is an attractive prospect that should take effect immediately. It would provide the benefit of sustainability in the transport sector such as fueling efficiency and reduced air pollution. However, realizing these benefits would require the economic and reliable production of hydrogen gas from low-carbon sources. In addition, its distribution using fleet vehicles should be reliable. Therefore, fuel-cell vehicles are more efficient and environmentally safe than any of the existing conventional vehicles in the market.
