Hydrogen Future Doubts
On the future of hydrogen in doubt
It is said that hydrogen can be the choice of future energy. However, upon closer inspection, there are many doubts that cannot be trusted.
The production of hydrogen is quite laborious. To obtain pure hydrogen, it is often necessary to borrow electricity or fossil fuels. If electricity is used to electrolyze water to produce hydrogen, a lot of energy has been lost in the power generation process, such as thermal power generation and coal combustion to generate heat and electricity. The energy conversion efficiency is limited and accompanied by environmental pollution. If hydrogen is produced by reforming fossil fuels, although the cost is slightly lower, it is still not off the dependence on traditional energy sources, nor does it reduce the risk of greenhouse gas emissions. It is difficult to call it a clean way.
Furthermore, the storage and transportation of hydrogen are difficult. Hydrogen is highly volatile and flammable, requiring special storage equipment. High-pressure gaseous storage requires a strong pressure-resistant container, which is expensive and safe to consider; low-temperature liquid storage, although it can increase the storage density, needs to maintain a very low temperature and energy consumption is huge. As for transportation, pipeline transportation requires special materials to prevent hydrogen embrittlement, and the construction cost is extremely high; vehicle transportation is limited by storage conditions, and the transportation volume is limited, making it difficult to meet large-scale energy demand.
The application field of hydrogen is not smooth sailing. In the automotive industry, although the theoretical prospects of hydrogen fuel cell vehicles are good, the practical promotion is blocked. Hydrogen refueling station infrastructure is scarce, few, far less than the convenience of gas stations. And the cost of hydrogen fuel cells remains high, technical stability still needs to be improved, consumers have many concerns, and sales are difficult to make great progress. In the industrial field, some traditional industries want to switch to hydrogen as energy, but also face the huge cost of equipment transformation and the problem of technical adaptation, which is difficult to see results in the short term.
To sum up, although hydrogen has potential, it still faces serious challenges in terms of production, storage, transportation and application. Looking at the current situation alone, it is too early to say that hydrogen is the future energy choice. The future of hydrogen can only be discussed after major technological breakthroughs, significant cost reductions, and complete infrastructure.
