[Haichuan New Energy] China’s first megawatt-class hydrogen energy comprehensive utilization demonstration station put into operation in Lu’an, Anhui

The plant utilizes a single-tank 250-kilowatt design with four-tank parallel control technology. It features China’s first megawatt-class proton exchange membrane (PEM) pure water electrolysis system for hydrogen production; at its rated hydrogen production capacity, it generates 220 cubic meters of hydrogen per hour. The system’s hydrogen production efficiency reaches 85%, exceeding the requirements for **Grade 1 energy efficiency, and it is capable of operating in response to fluctuations in renewable energy input

The system utilizes a technology that integrates 24 stacks, each with a capacity of 50 kilowatts, resulting in a maximum power output of 1.2 megawatts. It represents China’s first megawatt-class proton exchange membrane (PEMFC) fuel cell power generation system. This system features high conversion efficiency, no pollution, rapid startup at room temperature, no electrolyte leakage, easy water removal, long service life, as well as high specific power density and specific energy. It can provide controlled load and flexible power supply for power systems, assisting in peak shaving and frequency regulation to facilitate the utilization of renewable energy sources

Proton exchange membrane fuel cells offer advantages such as high energy conversion efficiency, high power density, low noise levels, and zero emissions, which has drawn significant attention from governments and research institutions around the world. In the future, they are expected to be used in various applications including vehicles such as cars, airplanes, and trains, as well as in fixed power plants. Currently, factors such as global warming and air pollution are continuously reducing the scope for the use of fossil fuels ； On the other hand, breaking free from dependence on non-renewable resources such as oil has become an important issue for future sustainable development. Therefore, the ability to develop and utilize various clean energy sources such as wind energy, solar energy, and tidal energy has become increasingly crucial. Hydrogen energy can precisely serve as an excellent medium for promoting the use of clean energy; through the conversion between electrical and chemical energy, it enables various methods such as decentralized production, storage, and utilization. Unlike pure electric vehicles, fuel cell vehicles achieve a \"separation\" in time between power generation at the upstream stage and power consumption at the end stage, which enhances hydrogen energy’s complementary role compared to wind and solar energy, which are subject to greater volatility (the technology approach used in pure electric vehicles). Therefore, the development of hydrogen energy and hydrogen fuel cells holds great strategic significance for energy. Currently, hydrogen fuel cell vehicles have entered the market introduction phase. Fuel cell cars such as Toyota Mirai from Japan, Honda Clarity, and Hyundai Nexo from South Korea are already available commercially, and their performance and range are comparable to those of conventional gasoline vehicles. The power level of fuel cell stacks used in passenger vehicles is generally around 100 kW, whereas that of fuel cell stacks used in commercial vehicles is usually in the range of 30 to 200 kW. Affected by various factors such as technical capabilities, infrastructure, and overall costs, fuel cell commercial vehicles in China have seen rapid development in recent years, at a pace significantly faster than that of fuel cell passenger vehicles. After more than a decade of investment in research and development, fuel cell technology in China has become more mature. Fuel cell buses represented by companies such as Foton Auman, Zhengzhou Yutong, and Foshan Feichi are gradually entering the market, and fuel cell logistics vehicles now also meet the conditions for commercial deployment. According to statistics from the China Association of Automobile Manufacturers, as of December 2018, the sales volume of fuel cell vehicles in China had reached 1,527 units.
