Although the reading passage lists three advantages of hydrogen energy, the speaker argues that these advantages are eclipsed by corresponding disadvantages.
The reading passage suggests that hydrogen energy is abundant to use because it originates natural resouces. However, this argument is shortsighted. Even though resouces are plentyful, it is very expensive to change to hydrogen. According to the speaker, the argument that hydrogen energy is relevant does not sound appealing.
The reading passage also maintains that using hydrogen source is friendly enviormental because it does not create harmful gases. This can certainly be the case, but it is also case that process of making hydrogen gas always rely on electricity. As the speaker points out, the claim that hydrogen energy is eco-product is not convincing.
Finally, the reading passage asserts that hydrogen source is easy to handle. The speaker, however, argues that it is complex to store and tranport because gas has a volatile possibility and it is too heavy to move. This reality renders the last argument for advantage of hydrogen energy in the reading passage unreasonable. |
