1. cost: especially the initial construction cost is still higher than that of generators, so it is difficult to popularize. Although the cost has also decreased with the progress of technology, there is still a way to go. 2. High technical threshold: manufacturers, sellers and consumers all need certain skills or training, which is not easy to achieve at present. 3. Infrastructure coordination: the focus is on fuel supply. Whether upgrading with natural gas or oil and gas, or directly using hydrogen, supporting infrastructure is needed, which is also a big expense.
