The content of the leading and the listening is totally opposing to each other in whether or not the hydrogen-based fuel-cell engine will replace the internal-combustion engine.
To begin with, the reading indicates that hydrogen is easily available, which is contradictory to the speaker who says that the reading is way too optimistic. The hydrogen that is derived from natural gas and water isn't directly usable until it is purified into a liquid state which is technically hard to produce and store.
In the second place, it is suggested from the reading that hydrogen-based fuel cells could solve the pollution problems. The speaker refutes this idea because the process to generate the hydrogen and to purify it will lead to harmful by-products due to the burning of fossil fuels.
Lastly, the reading points out that a fuel-cell powered car is much cheaper than the internal-combustion powered car because they are more efficient. Nevertheless, the speaker disproves it by putting forth the idea that it is not necessary for a fuel-cell automobile to be cheaper. The manufacture of hydrogen will cause more money because it requires additional material that is very expensive.
