  According to Sinochem New Network, recently, the 5-megawatt alkaline-proton exchange membrane hybrid system developed through collaboration between **Energy Group’s Beijing Low-Carbon Clean Energy Research Institute** and **Energy Group’s Guohua Investment (Hydrogen Energy Company)**, Guoneng Hydrogen Innovation Technology (Beijing) Co., Ltd., as well as the Kay Gung Innovation Laboratory and Xi’an Jiaotong University, passed the evaluation of scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation. The experts present agreed that this achievement is at an internationally leading level overall.   It is reported that this achievement was made possible through the **Key Research and Development Program project “Key Technologies and Demonstrations for 10 MW-class Alkaline-Proton Exchange Membrane Hybrid Hydrogen Production Systems”**. It enables stable operation over a very wide range of loads, from 16% to 160%, with a response time as low as 10 seconds. The overall energy consumption is as low as 4.3 kWh per standard cubic meter, while the accuracy in tracking renewable energy sources reaches 96.7%. This solution addresses two key technical challenges: adapting to fluctuations in wind and solar power output and controlling the energy consumption associated with hydrogen production. Project 1 led by the Energy Storage Center of the Low-Carbon Institute, titled “Design of a Hybrid Electrolysis Hydrogen Production System,” introduces an innovative approach to the coordinated design of processes and controls for alkaline-proton exchange membrane hybrid systems that takes into account uncertainties in energy supply and demand. It also incorporates AI-driven fault-tolerant control techniques based on multi-source information, thereby creating a design framework for hybrid hydrogen production systems that integrate electricity and hydrogen production. This framework provides essential technical support for the implementation of such systems, significantly enhancing the capacity for on-site utilization and efficient conversion of wind and solar renewable energy, and contributing to the development of a new type of energy system that makes use of both electricity and hydrogen.   Currently, this achievement has been successfully applied to the Qingshuiying hydrogen production plant in Ningdong, Yinchuan, Ningxia, where operational tests in summer and winter were carried out to fully verify the stability and reliability of the system under different climate conditions. Next, the project team will focus on promoting the large-scale application of the **major new energy project involving coal-to-oil and gas production by energy groups, in order to support the implementation of the strategy related to coal-to-oil and gas production.
