The Chemical Engineering Institute's "Specialized, Fine, and Novel" Green Hydrogen-Ammonia-Alcohol-Oil Technology Project Series has been approved as three major science and technology initiatives by China Electric Engineering Corporation.

        Recently, ‌ China Power Engineering Consulting Group Co., Ltd. (referred to as "CPECC") officially released its 2025 annual science and technology project approval plan. Among the projects, the Chemical Engineering Institute and China Energy Engineering Hunan Institute have been approved to lead one major science and technology special project and participate in two others. These projects cover key research areas and cutting-edge industry fields, including the critical technology for low-temperature, low-pressure green ammonia synthesis based on "three flexible couplings" in off-grid scenarios, as well as a 100-ton-scale CO2 hydrogenation technology for producing olefins and aviation fuel.

This time, the institute has been approved to lead a major science and technology project titled "Key Technologies and Demonstration Application of 'Triple Soft Coupling' Green Ammonia Synthesis at Low Temperature and Pressure Based on Off-Grid Scenarios," under China Electric Engineering Corporation. Additionally, it will participate in two other significant projects: "Research on Key Technologies and Equipment for Flexible SAF Synthesis via Microreactor Integrated FTS-HC Process" and "Research and Demonstration of 100-Ton-Scale CO2 Hydrogenation Technology for Producing Aviation Fuel Olefins." These research initiatives are closely aligned with cutting-edge emerging industry trends, enabling the Institute of Chemical Engineering and China Energy Engineering Group Hunan Institute to further advance the practical application of core technologies. They will also drive forward R&D efforts in areas such as chemical-energy integration and low-carbon transformation, ultimately supporting the vision of China Energy Engineering Group Hunan Institute to become "industry-leading and domestically first-class."

The Institute of Chemical Engineering, as the sole chemical design institute under China Energy Engineering Group's China Electric Engineering Corporation, along with China Energy Engineering Hunan Institute and its affiliated chemical institute, is the only domestic entity holding dual Class-A engineering design qualifications—covering both power and chemical industries. They possess unique advantages in large-scale new-energy base projects combined with green hydrogen-ammonia-methanol production, including "superior base-planning capabilities, advanced energy-chemical technology expertise, and robust system-integration strengths." The institute also boasts a solid theoretical foundation and practical application in optimizing power-source capacity allocation, enabling flexible, coordinated, and optimized configurations across the entire wind-solar-storage-hydrogen-ammonia-methanol process flow. Additionally, they bring extensive experience in traditional ammonia and methanol synthesis design. In the burgeoning field of hydrogen energy, particularly in integrated electro-hydrogen-ammonia-methanol technologies, the institute has been placing significant emphasis in recent years on Efforts are underway to tackle key technologies in areas such as multi-stable green ammonia synthesis, flexible green ammonia synthesis under low temperature and pressure, biomass gasification integrated with green hydrogen for producing sustainable methanol, and the production of methanol from non-fossil CO₂ combined with green hydrogen. In 2024, the "Integrated Technology Platform for Hydrogen-Electricity-Ammonia-Methanol in the Emerging Energy Sector," jointly submitted by China Energy Engineering Group Hunan Institute and the Chemical Engineering Institute, was successfully selected as a project under Hunan Province's 2024 Central Government-Funded Local Science and Technology Development Program. This milestone marks a significant breakthrough for the green hydrogen-ammonia-methanol strategy, securing central government funding to support local scientific research initiatives.

In the area of green hydrogen. The Institute of Chemical Engineering's research and development in the green hydrogen field began with fundamental studies on water electrolysis technology, gradually expanding into system integration and application technologies. Currently, its work covers the two mainstream technologies—alkaline water electrolysis (ALK) and proton exchange membrane water electrolysis (PEM)—and the institute has successfully initiated and participated in multiple research projects related to green hydrogen. The State Intellectual Property Office has authorized the Institute of Chemical Engineering, together with China Electric Engineering Corporation, to jointly engage in "Invention Patent: A Proton Exchange Membrane (PEM) Hydrogen Production System and Control Method Capable of Switching Between Balanced and Differential Pressure Operating Modes" This technology breaks through the single-operation limitations of traditional hydrogen production systems, enabling seamless switching between balanced and differential-pressure modes, thereby injecting new momentum into the proton exchange membrane (PEM) electrolysis hydrogen production industry.

        Regarding green ammonia: (1) The direction of multi-stable green ammonia synthesis technology. Building upon traditional ammonia synthesis techniques, we have developed a proprietary, full-system, multi-stable green ammonia synthesis process package along with specialized technologies. We can provide comprehensive technical services, including project planning, feasibility studies, basic design, and detailed engineering for related projects. The co-authored "Technical Requirements for Integrated, Multi-Stable, Flexible Ammonia Synthesis Technology Combining Wind, Solar, Hydrogen, and Ammonia/Ethanol Storage" green ammonia group standard has been officially released and implemented. (2) Research is also underway in the direction of low-temperature, low-pressure, flexible green ammonia synthesis processes. The design of a reactor, green ammonia process, and advanced control system tailored for 10,000-ton-scale low-temperature, low-pressure flexible green ammonia has been completed. Building on the completed static simulation calculations, dynamic simulations of the process system and reactor have been conducted to verify the compliance, safety, and economic viability of the synthesis reactor, process design, advanced control system, and the entire integrated system—aiming for optimal performance, intrinsic safety, and cost efficiency. Based on the dynamic simulation results, refined and optimized designs will be implemented in subsequent engineering projects.

Regarding green methanol. (1) In the area of biomass gasification coupled with green hydrogen for producing green methanol, the Syr-Daq project has demonstrated the operational flexibility of integrating conventional methanol synthesis processes with green hydrogen. During the later stages of project implementation, a proprietary process package and engineering design for biomass gasification integrated with green hydrogen to produce green methanol were developed. The co-authored group standard "Technical Specification for Biomass-to-Methanol Production," formulated by the China Inspection and Testing Association, has been officially released and put into effect. (2) From non-fossil sources CO ₂ + Regarding green hydrogen-to-methanol production, we have completed surveys and technical exchanges with several catalyst production research units, enabling us to select suitable catalyst research institutions for collaborative technology partnerships. We now possess the capability to integrate process technology routes and catalyst systems into comprehensive design solutions, as well as develop proprietary key technologies.

Especially in the integrated technology for green ammonia production via the flexible coupling of electricity, hydrogen, and ammonia, Based on the characteristics of the large-scale new energy hydrogen project, there is a highly integrated and collaborative effort involving China Energy Engineering Group Hunan Institute’s power system planning department, the New Energy Engineering Company, and other relevant divisions—spanning from the power system and new-energy front-end all the way to the backend hydrogen-ammonia-alcohol chemical processing section, ultimately creating A Set of Three Soft Craft Techniques (Flexible microgrid, flexible hydrogen production, flexible ammonia production) Two types of AI models (Electric-Hydrogen-Ammonia Synergistic Flexible Interaction System Configuration Model, Optimization Control Model Adapted for Three-Flex Processes) Three typical microgrid solutions (Grid-connected, Interconnection Switch Type, Standalone Type) — Promote multiple real-world application scenarios 。
