Green hydrogen industry is an organic part of the modern industrial system
Under the constraints of the carbon neutrality goal, the green hydrogen industry is an essential part of the modern industrial system. The role of green hydrogen in carbon neutrality in the industrial sector is mainly reflected in three aspects: decarbonization of industrial processes, balance of new power systems, and decarbonization of transportation.
1. Green hydrogen is a weapon for some industrial processes to achieve carbon neutrality
“Hydrogen” is an important industrial raw material, material and fuel, and is widely used in industrial production processes. The current industrial hydrogen is “gray hydrogen”, and its carbon dioxide emissions are also an important source of carbon emissions from these industrial production. According to statistics from the China Hydrogen Energy Alliance, my country’s hydrogen production is 40 million tons, of which 80%, or 32 million tons, are used in industrial production processes. 78% of the hydrogen produced comes from coal or natural gas. Therefore, the production of green hydrogen through electrolysis of water from renewable energy gradually replaces these gray hydrogens, which has become an effective way to decarbonize these industrial production processes. In addition, in the steel industry, the current process technology innovation and improvement is difficult to achieve deep decarbonization. Hydrogen metallurgy is the most feasible way to replace carbon reduction. Therefore, green hydrogen plays a decisive role in the deep decarbonization of the steel industry.
2. Hydrogen storage plays a key role in balancing seasonal fluctuations in new power systems
Unlike the current power system, the new power system based on fluctuating renewable energy sources will face unique seasonal balance problems. For example, Europe has long sunshine hours from April to October, and solar power generation has increased significantly, resulting in excess electricity. From October to April of the following year, the sunshine hours decrease, and solar power generation decreases significantly, resulting in insufficient power supply. The minimum power generation during this period is even only half of the maximum power generation during the period from April to October. This creates the need for seasonal balance of power supply and demand. Green hydrogen energy storage systems can store energy for long periods of months or quarters due to their large capacity, long cycle, clean and efficient characteristics, and are considered to be a storage method that can well match renewable energy power. Moreover, compared with pumped storage, hydrogen energy storage is less restricted by geographical factors, and its storage capacity can be expanded at a lower marginal cost by increasing the size of hydrogen storage tanks.
3. Green hydrogen is an important path to achieve decarbonization of transportation
Transportation is an important application area of hydrogen energy. At present, electrification and electrification of ground transportation are the main ways to decarbonize transportation, but there are still some areas where electrification is not dominant, such as heavy-duty trucks, ocean shipping and aviation, which may eventually need to rely on green hydrogen to achieve decarbonization.
The decarbonization of heavy-duty transportation, long-distance shipping and aviation transportation currently mainly uses fuels produced from biomass, waste or other renewable resources to partially replace the current fuels from fossil energy. For example, the EU stipulates that the proportion of biofuel added to all aviation kerosene must reach 2% in 2025, and will be increased every 5 years thereafter until it reaches 70% in 2050. However, the supply of bio-based fuels is ultimately limited. In the medium and long term, the decarbonization of these areas may also be inseparable from technical routes related to hydrogen energy.
Hydrogen production by electrolysis of water is the most advantageous method for producing hydrogen. Utrasonic coating systems are ideal for spraying carbon-based catalyst inks onto electrolyte membranes used for hydrogen generation. This technology can improve the stability and conversion efficiency of the diaphragm in the electrolytic water hydrogen production device. Cheersonic has extensive expertise coating proton exchange membrane electrolyzers, creating uniform, effective coatings possible for electrolysis applications.
Cheersonic ultrasonic coating systems are used in a number of electrolysis coating applications. The high uniformity of catalyst layers and even dispersion of suspended particles results in very high efficiency electrolyzer coatings, either single or double sided.
