The author states that the hydrogen based fuel-cell engines are better than petrol and diesel engines and he presents three hypotheses to prove his point. However, the lecturer rebuts his view point by providing following justifications.
First, the author says that though the hydrogen is plentiful in the environment and petrol is a finite source of energy but it cannot be the substitute of petrol. The lecturer refutes this point and explains that although the hydrogen is present in the environment in a huge amount in natural gas and water but it cannot be utilized in its original form. In fact it has to be obtained in liquid form which is intricate. To produce and to store hydrogen in liquid form requires -200 degree Celsius temperature which is not at all a practical solution.
Second, the professor challenges the point said in the passage that hydrogen based fuel-cell engine will not cause pollution. He clears the doubt by telling that the factories burn coal and oil in the process of transforming the hydrogen into pure usable form that causes massive pollution. Thus, all the points made in the reading are contraindicated by the lecturer.
Last but not the least, the lecturer challenges the statement made in the passage that the hydrogen based fuel-cell engine are more economical than petrol engines. He tells that the energy used to undergo the process to generate the energy to run the engine requires components that are made up of platinum which is extremely expensive. Hence, it is not true o say that using hydrogen is cheaper.
