1. technical problems: the hydrogen energy industry needs to solve the technical problems of hydrogen production, storage, transportation and utilization, and these technologies are not mature enough at present.
2. Cost: The cost of hydrogen energy industry is high, which requires a lot of investment and support. At present, a complete industrial chain and market have not been formed.
3. It is difficult to transform the energy structure: At present, China's energy structure is dominated by coal, oil and natural gas, so it is very difficult and challenging to transform into hydrogen energy.
4. Insufficient market demand: At present, the market demand of hydrogen energy industry is still insufficient, which needs the joint promotion of the government and enterprises to realize the development of the industry.
5. Environmental protection: The hydrogen energy industry needs a lot of clean energy to produce hydrogen. If traditional fossil energy is used, it will have a great impact on the environment.
