A Hydrogen Electrolysis Rectifier is a specialized electrical device used to convert alternating current (AC) from the power grid into direct current (DC) for hydrogen production through electrolysis. In this process, the rectifier provides the stable and controlled DC voltage needed to split water into hydrogen and oxygen gases. This power supply is essential for efficient and reliable hydrogen production in various applications, including industrial hydrogen generation, fuel cell technology, and renewable energy storage. It features high efficiency, precise voltage regulation, and safety features to manage the electrolysis process effectively and support the growing demand for clean hydrogen energy solutions.
Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called electrolyze. Electrolyzes can range in size from small, appliance-size equipment that is well-suited for small-scale distributed hydrogen production to large-scale, central production facilities that could be tied directly to renewable or other non-greenhouse-gas-emitting forms of electricity production.
The DC power supply required for electrolyzing water to produce hydrogen generally has higher voltage and lower current. This means that in the rectifier transformer, the voltage will be greatly increased and the current will be reduced accordingly.
Therefore, the design of the rectifier transformer must take into account the voltage and current requirements to ensure that the process of electrolyzing water to produce hydrogen is as efficient as possible. In addition to voltage and current requirements, the stability of the rectifier transformer is also one of the key factors. This is because once the output of the rectifier transformer is unstable, it will affect the process of electrolyzing water to produce hydrogen and may cause equipment damage or other problems. Therefore, stability is a factor that must be considered when designing a rectifier transformer.
Electrolysis is a promising option for hydrogen production from renewable resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyze. Electrolyzes can range in size from small, appliance-size equipment that is well-suited for small-scale distributed hydrogen production to large-scale, central production facilities that could be tied directly to renewable or other non-greenhouse-gas-emitting forms of electricity production.
Nowadays, 96% of the global hydrogen produced comes from the use of fossil fuels (i.e., natural gas, oil); whereas production from water electrolysis represents only 4%. Indeed, the cost of hydrogen production by using fossil fuels is smaller than water electrolysis given that current electrolyzers are quite expensive and the cost of electricity as well. However, hydrogen production based on fossil fuels, namely gray hydrogen, suffers from lower purity and higher generation of greenhouse gases.
To face the intensive use and depletion of fossil fuels to respond to hydrogen demands, water electrolysis supplied by renewable energy sources (e.g., wind turbine, photovoltaic) is considered an attractive and promising alternative. Renewable energy sources combined with water electrolysis come within the scope of the development of environmentally friendly hydrogen production pathways to substitute current hydrogen production based on pollutant fuels. Water electrolysis can produce hydrogen at high gas purity but features high cost (electrolyzer, electricity) and lower energy efficiency due to a high specific energy consumption. For this reason, energy efficiency, cost of electricity, and water electrolysis systems remain major concern to the development of water electrolysis process at a large scale. The water electrolysis process consists of using electricity coming from the power grid or renewable energy sources to split pure water into hydrogen and oxygen.
Hydrogen electrolysis rectifier power supplies, typically referring to rectifiers or DC converters, act as the crucial link between the power grid and electrolyzers. They rely on power modules to convert AC or DC electricity into the direct current required for water electrolysis. As green hydrogen production scales up, improving conversion efficiency, adapting to various application scenarios, minimizing energy losses, and extending equipment lifespan have become the core focus areas in the technological advancement of hydrogen production rectifier systems.
In 2024, the global production of industrial and refining hydrogen remains predominantly reliant on fossil fuels, generating net direct carbon dioxide emissions exceeding 650 million tons and 200 million tons, respectively. Key industrial processes such as synthetic ammonia, methanol production, and refining utilize hydrogen as a primary feedstock. Given the maturity of these processes, significant carbon reduction potential exists by transitioning from conventional gray hydrogen to green hydrogen alternatives. Furthermore, regions worldwide are actively exploring innovative applications of hydrogen across diverse sectors to displace gray hydrogen and advance decarbonization efforts.
The integration of wind, solar, and hydrogen production is accelerating, leading to an increase in the scale of single-cell hydrogen production and driving the expansion of rectifier power supplies for hydrogen generation. Green hydrogen projects are experiencing rapid growth, with individual project capacities continually rising. On one hand, as the hydrogen output capacity of electrolyzers improves, the power requirements for rectifier systems are expected to increase accordingly. On the other hand, with the growing scale of wind and solar power generation and the expanded use of surplus renewable electricity for hydrogen production, the market share of PEM water electrolysis technology continues to rise. Against this backdrop, the market share of IGBT-based rectifier power supplies for hydrogen production is also expected to increase.
