GLOBAL CRISES IMPACTING RECTIFIERS FOR HYDROGEN ELECTROLYSIS MARKET

COVID-19 IMPACT

Rectifiers for Hydrogen Electrolysis Industry Had a Negative Effect Due to supply disruptions and delayed hydrogen projects during COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The Rectifiers for Hydrogen Electrolysis Market was impacted negatively during the COVID-19 pandemic, primarily due to interruption in global supply chains and shutdown of production. Lockdowns and bans resulted in delayed industrial projects like hydrogen manufacturing plants that reduced the demand for rectifiers. Labor shortages and transport disruptions slowed down production and installation activities of several firms. Besides, lower investment in renewable energy projects during the initial pandemic phase also postponed market growth accordingly. Overall, the pandemic suspended market movement temporarily and slowed down its growth significantly during this period.

LATEST TREND

Market Growth Driven by Sic/Gan Tech and Modular Rectifiers

One of the more recent advancements in the Rectifiers for Hydrogen Electrolysis Market is the increasing use of even broader-bandgap semiconductors like silicon carbide (SiC) and gallium nitride (GaN) to increase rectifier efficiency and thermal performance by a significant margin. The materials enable rectifiers to operate at increased voltages and temperatures using fewer energy losses, a desirable attribute as systems become increasingly coupled with variable renewable energy sources such as wind and solar. The other trend is the need for small, modular rectifier modules that will be sized proportionally with various electrolyzer sizes and site conditions. Also on the rise is the application of high-pulse configurations of 12-pulse and 18-pulse rectifier sets, since they are capable of handling increased power loads and harmonics reduction. Emphasis is especially laid on SiC/GaN-enabled rectifiers since these technologies not just render energy consumption more efficient but also support more sustainable and scalable green hydrogen production.

RECTIFIERS FOR HYDROGEN ELECTROLYSIS MARKET SEGMENTATION

BY TYPE

Based on Type, the global market can be categorized into 6 Pulse, 12 Pulse & 18 Pulse

6 Pulse Rectifiers: 6 Pulse rectifiers are the easiest to use in hydrogen electrolysis, presenting a cheap and simple low to medium power application solution. They create higher harmonic distortions, however, something that would deflate system power quality and efficiency. The rectifiers are extensively used in miniaturized electrolysis systems where expenses are of utmost concern. As much as they are limited, they continue to experience widespread popularity in developing nations as well as pilot hydrogen projects.

12 Pulse Rectifiers: 12 Pulse rectifiers are an improvement over 6 Pulse systems with improved power quality and significantly lesser harmonic distortions. They are more suitable for medium- to large-scale hydrogen production plants since they are efficient and have more stable DC output. Phase-shifting transformers are utilized in the system to enhance performance and reliability. With increased hydrogen production, 12 Pulse rectifiers are being given greater attention for their cost-performance ratio.

18 Pulse Rectifiers: 18 Pulse rectifiers form the top-of-the-line product range, offering high-quality power and extremely low harmonic content for heavy and continuous hydrogen electrolysis loads. The rectifiers ensure stable operation and increased compatibility with sensitive electrical equipment. While expensive, their efficiency, grid standard compliance, and minimal maintenance needs justify investment for heavy or mission-critical hydrogen applications. Their uses are increasing in utility-grade green hydrogen plants and advanced industrial processes.

BY APPLICATION

Based on application, the global market can be categorized into Electrolyser Manufacturers & Hydrogen Producers

Electrolyser Manufacturers: Electrolyser producers depend on high-performance rectifiers for the provision of reliable and efficient DC power required by electrolysis.

With manufacturers designing to ramp up hydrogen production, there is an increased demand for smaller and modular-style rectifier systems. Advances in rectifier technology are allowing electrolyser producers to provide more energy-efficient and affordable solutions to numerous end-use industries.

Hydrogen Producers: Hydrogen producers utilize rectifiers as a critical part for the conversion of renewable electricity into hydrogen via electrolysis. Hydrogen producers, in order to have high reliability, low harmonic distortion, and low energy loss, need rectifiers to facilitate economically sound operations. As the world goes green with hydrogen, producers are moving towards superior rectifier systems that can be easily integrated into variable renewable energy sources. The scalability and efficiency of rectifiers directly affect the viability and profitability of hydrogen production facilities.
