Review of Wind-Solar-Hydrogen-Ammonia-Methanol Integrated Technologies and Industry

ObjectivesAs clean energy sources and chemical raw materials, green hydrogen, green ammonia, and green methanol play an important role in achieving the “dual carbon” goal. With the increasing demand for clean energy, wind-solar-hydrogen-ammonia-methanol integrated industry has emerged as an important new field of interest. However, the industry in China is still in its early stages of development, with numerous challenges in various links of the industry chain. Therefore, it is necessary to explore the technologies related to wind-solar-hydrogen-ammonia-methanol integration and to analyze the future direction of its development.MethodsFirstly, the technological routes of producing green hydrogen, synthesizing green ammonia, and synthesizing green methanol through water electrolysis are introduced, along with an overview of technologies addressing the instability of wind and solar power. Next, the economy of the wind-solar-hydrogen-ammonia-methanol integrated industry are analyzed, highlighting the implementation of key projects and related policies in recent years. Additionally, the electricity and water consumption for producing green ammonia and green methanol are analyzed and estimated, and the production costs of green hydrogen, green ammonia, and green methanol are predicted. Based on this, suggestions for industry development are proposed, including technological innovation, industry chain coordination, and policy support. Finally, the future development directions of the wind-solar-hydrogen-ammonia-methanol integrated industry are analyzed.ConclusionsIn the future, the integrated development of wind-solar-hydrogen-ammonia-methanol will show a trend of technological integration, diversified applications, regional coordination, and cost-effectiveness, making it one of the core pathways to achieve the “dual carbon” goals and transform the energy system.
