Recently, the launch ceremony for the full-power testing of the world’s first offshore 1,000-square-meter proton exchange membrane (PEM) electrolyzer and hydrogen production system was held at the testing facility in Nantong, Jiangsu Province. It is reported that this electrolyzer was independently developed by Shanghai Hydrogen Morning New Energy Technology Co., Ltd., which is funded by Shenneng Group Co., Ltd., and its subsidiary, Shanghai Hydrogen Shengchuanghe Energy Technology Co., Ltd. The electrolyzer features new materials and a highly reliable packaging design, with a hydrogen production capacity of 1,000 standard cubic meters per hour, enabling it to meet the demands of large-scale hydrogen production. At the same time, designed for offshore floating platforms, the system reduces its overall weight to 1/6 that of traditional alkaline hydrogen production systems through an integrated and modular architecture. It also incorporates various innovative technologies such as high-durability materials, efficient mass transfer flow fields, precise assembly, and high-efficiency control. These features enable it to operate stably over long periods in harsh marine environments, offering resistance to corrosion, wind and waves, as well as being lightweight. It is worth noting that this electrolyzer also supports remote intelligent control and unmanned operation and maintenance; its dynamic response time is reduced to 5 seconds, and its direct current power consumption is below 4.3 kWh per cubic meter. This enables it to adapt perfectly to the fluctuations in power output from offshore wind turbines, thus achieving integration between wind power generation and hydrogen production. A responsible official from Shenneng Group said that converting offshore wind energy into hydrogen for transmission can reduce costs by more than 30% compared to traditional undersea cables, and the economic advantages become more significant as the transmission distance increases. Technological breakthroughs in high-power PEM hydrogen production systems capable of adapting to deep-sea environments and the volatility of wind power have provided a new approach for the large-scale development of deep-sea wind energy resources. This offshore hydrogen production system will be demonstrated next year at the Sheneng Hainan CZ2 offshore wind farm, converting currently difficult-to-develop deep-sea wind energy resources into carbon-free fuels such as green hydrogen and green ammonia, which will then be transported by pipelines or ships to coastal areas or for export, thereby supporting the energy transition and the implementation of the strategy to build a strong maritime nation. Similar approaches are also expected to become one of the mainstream technical routes for exploiting offshore wind energy resources. In the future, SHENENG Group will continue to increase its investment in technological innovation in the field of hydrogen energy, promote the high-quality development of the hydrogen energy industry, and provide new solutions to help China achieve its \"dual carbon\" goals.
