Most of the cars running on the street today use petroleum products as fuel, the problem with petroleum is that it’s a finite resource and causes pollution when used. The passage suggests hydrogen fuel cells as a better alternative for petroleum. However, the lecturer believes hydrogen is not a practical solution yet and refutes all the benefits of Hydrogen fuel cell discussed in the passage.
First, Hydrogen required to make fuel cells is not readily available. The hydrogen from atmosphere has to be converted into pure liquefied Hydrogen, this is a complex process and requires sophisticated cooling technologies. Incorporating such technologies practically for mass manufactured cars in not yet possible. Hence, the passage’s claim of Hydrogen fuel cells being an alternative is overly optimistic.
Morevoer, the purification process of converting Hydrogen into pure liquefied Hydrogen is also a high energy task, fuels such as coal or oil would have to be used. Hence, although the Hydrogen powered car may not contribute to pollution, but the process to make Hydrogen fuel cells will release many harmfull green house gasses such as co2. The passage’s assessment that Hydrogen fuel cells are environment friendly, does not stand ground.
There is no doubt that present internal combustion engines are very inefficient, and a hydrogen fuel cell can easily achieve double the efficiency of an internal combustion engine. However, an increase in efficiency does not correspond to cheaper operation of the car. The sophisticated hydrogen fuel cell technology is very expensive, components have to be made up of rare earth metals like platinium. Hence, it is unlikely for such expensive technology to be incorporated in cars any time soon.
Both the lecturer and the reading passage agree on the negative impact of using fossil fuel for cars. However the reading passage grossly overestimates the practicality of using Hydrogen fuel cells as an alternative. The lecturer highlights that there are numerous challenges that Hydrogen fuel cells need to overcome, for them to be part of mass produced cars.
