Megawatt-Class PEM Electrolyzer-BriLyzer®-R200 Gen 2 of BriHyNergy Achieves Successful Operation
Industry newsThe 200standard cubic meters PEM electrolyzer independently researched and developed by BriHyNergy has a rated hydrogen production capacity of 200 standard cubic meters/hour in a single tank. The electrolyzer can operate stably within a wide power input range of 5%-125% to directly produce 3.5MPa high-pressure hydrogen, realizing minute-level start-stop and second-level dynamic response, which is highly adapted to the fluctuating nature of wind power, and is suitable for large-scale PEM electrolysis of water for hydrogen production.
The BriLyzer®-R200 Gen 2 employs a flexible and scalable automated PEM electrolyzer stacking platform (R Platform), capable of expanding unit hydrogen production capacity of 600 standard cubic meters per hour. Thanks to the application of BriPEM® dual-enhanced proton exchange membranes, multi-level self-sealing technology, highly consistent stacking process, and other technological innovations and process optimizations, the BriLyzer®-R200 Gen 2 achieves a significant reduction in energy consumption compared to the first-generation electrolyzer. At a current density of 2.5 A/cm², the rated energy consumption reaches 4.2 kWh/Nm³ H₂. Additionally, the BriLyzer®-R200 Gen 2 can stably produce hydrogen at a pressure of 3-4 MPa and withstand a peak pressure drop of up to 5 MPa, representing an improvement of over 40% compared to the industry average. By directly producing high-pressure hydrogen through the BriLyzer®-R200 Gen 2 electrolyzer, saving the cost of downstream hydrogen compression, which leads to an overall reduction in the investment cost of hydrogen storage and transportation.
The fully independently developed and produced BriPEM® dual-enhanced proton exchange membranes plays a key role in the successful operation of BriLyzer®-R200 Gen 2. The BriPEM® dual-enhanced PEM employ perfluorosulfonic acid resin as the solid electrolyte, offering excellent chemical stability and high proton conductivity. On the physical reinforcement level, the addition of a high-strength polymer reinforcement layer enhances the compressive strength of the membrane, improving its mechanical strength and dimensional stability. Simultaneously, on the chemical level, BriHyNergy ‘s proprietary dehydrogenation technology significantly reduces the hydrogen content in oxygen, ensuring the safety of the electrolyzer. Moreover, the unique scavenger employed can mitigate membrane aging, extending its service life. As core materials and components in PEM water electrolysis, proton exchange membranes and membrane electrode assemblies have high technical barriers, not only determining the performance of PEM electrolyzers but also influencing their cost. As the first domestically mass-produced dual-enhanced proton exchange membrane, BriPEM® dual-enhanced proton exchange membranes already commenced mass production and delivery in 2023, aiming to address the “bottleneck” issue of domestic supply of core materials for PEM water electrolysis.
BriHyNergy’s BriLyzer®-R200 Gen 2 has recently successfully obtained the EU CE certification. This certification marks both the recognition of BriHyNergy’s technological prowess and an authoritative endorsement of its product quality and safety. Renowned for its stringent standards and comprehensive testing procedures, the EU CE certification signifies that BriHyNergy’s MW-class PEM electrolyzer has reached international advanced levels in terms of design, manufacturing, performance, safety, and reliability. The acquisition of this CE “passport” for the European market has significantly enhanced the competitive advantage of BriHyNergy’s large-scale PEM electrolyzers in the global market, enabling the company to provide customers with more efficient, safer, and more reliable PEM hydrogen production products.
BriHyNergy is committed to developing PEM electrolyzers with higher efficiency, lower energy consumption, and greater reliability and durability in the future and will aim to accelerate the global adoption of green hydrogen technology and contribute to building a greener and cleaner world.
