The reading and listening passages discuss about Hydrogen energy. According to the reading passage, Hydrogen energy has been an attractive new source. On the contrary, the lecturer contradicts this by asserting that there are some disadvantages in the energy.
First of all, the professor claims that the cost of the energy is costly. To be specific, people should use more money in order to make the energy. This refutes author’s claims that the energy would be widespread availability and much cheaper.
Secondly, the author asserts that hydrogen energy is environmentally and rarely makes emission. However, the lecturer refutes this by insisting that there could be emission during the process of using it. In addition, it is not always feasible to use wind and sun.
Finally, the lecturer insists that storing and transporting are too dangerous. Moreover, the tank in a car will be very heavy. To be specific, it could be more than 3 kg so that the car could bring the energy. This refutes author’s claim that the advent of new technology to store allow people to be able to transport.
To sum up, about the energy, the professor maintains that the hydrogen is not good as much as the author think.
