Which is a major drawback to the use of hydrogen power?

the high cost

Explanation:

The hydrogen power has few key advantages when it comes to its usage. It is environment friendly, and the only thing released in the atmosphere from its usage is water vapor, which can be very useful especially in arid and semi-arid regions. Also, the fuel economy that it will propel is around two times more than that of the gasoline vehicles. But unfortunately, as most of the environment friendly energy sources, the same problem occurs with the hydrogen power, the cost of it. This power is still very expensive for production, thus it is also very expensive when it reaches the consumers, so at the moment it is not economically justifiable.
