“…However, the technology maturity of PEM with high cost is slightly lower than AWE. Compared with AWE technology, PEM electrolyzer has the following advantages [17,18]: (1) the solid electrolyte membrane enables a large pressure difference to be borne on both sides, which unidirectionally permits hydrogen ion conduction, isolates hydrogen and oxygen, and improves safety and conversion rates; (2) the thin PEM electrolyte film reduces the electrode spacing, resulting in lower voltage and energy consumption and a more compact tank structure; (3) the electrolyte is pure water, which is non-corrosive; (4) the electrolytic products are also kept clean; and (5) there is more flexible operation (load range 5~120%) [19].…”

Under the background of the power system profoundly reforming, hydrogen energy from renewable energy, as an important carrier for constructing a clean, low-carbon, safe and efficient energy system, is a necessary way to realize the objectives of carbon peaking and carbon neutrality. As a strategic energy source, hydrogen plays a significant role in accelerating the clean energy transition and promoting renewable energy. However, the cost and technology are the two main constraints to green hydrogen energy development. Herein, the technological development status and economy of the whole industrial chain for green hydrogen energy “production-storage-transportation-use” are discussed and reviewed. After analysis, the electricity price and equipment cost are key factors to limiting the development of alkaline and proton exchange membrane hydrogen production technology; the quantity, scale and distance of transportation are key to controlling the costs of hydrogen storage and transportation. The application of hydrogen energy is mainly concentrated in the traditional industries. With the gradual upgrading and progress of the top-level design and technology, the application of hydrogen energy mainly including traffic transportation, industrial engineering, energy storage, power to gas and microgrid will show a diversified development trend. And the bottleneck problems and development trends of the hydrogen energy industry chain are also summarized and viewed.
