Green Hydrogen Disadvantages
The disadvantages of green hydrogen energy
Today's hydrogen energy is respected by the world for its cleanliness, but green hydrogen energy also has various disadvantages.
First, the production of huge consumption. Green hydrogen energy is mostly obtained by hydrolysis, and in order to achieve this, a large amount of electricity is required. And in order to obtain a sufficient amount of electricity, it is often relied on renewable energy such as wind and photovoltaics to generate electricity. However, such power generation is subject to the weather and terrain, and it is difficult to supply energy consistently. To obtain sufficient green hydrogen, large-scale power generation facilities need to be built, which are expensive and expensive to operate and maintain. The cost of green hydrogen production is high and difficult.
Second, storage is difficult. When hydrogen is in the gaseous state, its density is extremely low. To store enough, it needs to be in a high-pressure or low-temperature environment. High-pressure hydrogen storage has extremely high material and safety standards for containers, and if it is slightly careless, it is easy to cause explosion; low-temperature hydrogen storage requires cryogenic technology, which greatly increases energy consumption, and the equipment is complex and costly. Even emerging methods such as solid-state hydrogen storage are still in the research stage, and they are not mature, and large-scale applications are blocked.
Third, the difficulty of transportation. The special properties of hydrogen make its transportation quite difficult. Long-distance transportation of gaseous hydrogen requires high-pressure pipelines, which are expensive to build pipes, and the risk of leakage along the way is inevitable; although liquid hydrogen transportation is relatively convenient, its low temperature requirements are harsh, and the transportation process consumes a lot of energy and loses a lot. In addition, the current lack of transportation infrastructure makes it difficult to provide strong support for the wide application of green hydrogen.
Fourth, the dilemma of efficiency. From electricity to hydrogen, and then from hydrogen to usable energy, there is a lot of energy loss in the process. The efficiency of hydrogen production by water electrolysis and the efficiency of hydrogen fuel cell power generation are not ideal. This multiple conversion loss results in low overall energy utilization efficiency, limiting the effectiveness of green hydrogen in the energy field.
To sum up, although green hydrogen energy has the advantages of cleanliness, its drawbacks in various aspects such as production, storage, transportation, and efficiency need to be overcome urgently in order to be widely used in the world and make every effort to improve the energy revolution.
