Lecture and reading discusses about substituting internal combustion engine with hydrogen based fuel cell engine. Reading talks about positive outcomes of using hydrogen based cell, while prefecture states that benefits of hydrogen based cell over internal combustion engine in reading are not logical.
First, reading states that petroleum is non-renewable source of energy, so in near future petroleum can no longer reproduced. Reading adds that hydrogen is easily available in the atmosphere in infinite quantity. Lecture casts doubt on this statement. She thinks that indeed hydrogen is always available in water, but can’t be used without processing. She thinks production of liquid hydrogen is very complicated and expensive process.
Second, reading points out that combustion of petroleum may contaminate environment. Furthermore, hydrogen based cell do not produce carbon dioxde. In contrast, lecture says that the process to obtain hydrogen in liquid form necessitates burning of coal and oil. She states that hydrogen cell might not reduce pollution because the factories to convert hydrogen emit smoke and harmful gases.
Third, reading implies that switching to hydrogen cell is cheaper option over internal combustion engine, as hydrogen cell is very efficient in producing energy. On contrary, lecture points out that platinum is used to form liquid hydrogen and its very expensive. However, other cheaper material failed to produce hydrogen. As a result she thinks that it is not economically feasible option. She successfully casts doubt on statements made in reading.
