China has recently kicked off a detailed strategy to develop its hydrogen economy, first rolling out 11 different types of demonstration projects. This task seeks to improve hydrogen production processes, storage methods, transportation systems, and hydrogen-use applications. It’s a key piece of the country’s overall plan to increase clean energy generation to 80 percent by 2035. The ambitious plan is emblematic of China’s pledge to lead in the development of sustainable energy technological revolutions and efforts to curb carbon emissions.
The endeavor consists of 68 unique pilot projects. Each one is strategically crafted to solve a piece of the hydrogen puzzle, from production to transportation. Of these eleven categories, three address production, two storage and transportation, and four end-use applications. By initiating these projects, China seeks to create a solid foundation for hydrogen use infrastructure through various sectors.
Key Production Initiatives
Of all the pillars within the hydrogen initiative, the production pilots are notable for their tough guidelines. Large-scale green hydrogen production facilities must achieve a minimum capacity of 100 megawatts or produce over 20,000 Nm3 of hydrogen per hour. Further, development pilots are required to demonstrate at least 1,000 tonnes per annum (tpa) of renewable hydrogen production.
Notably, Envision Energy’s 500 megawatt project in Chifeng commenced production last year, serving as a significant example of China’s commitment to scalable hydrogen generation. This project is a great example of the kind of big, transformative projects that the Reconnecting Communities Initiative is trying to encourage more of across the nation.
Storage and Transportation Requirements
The new initiative fleshes out parameters, including detailed criteria for storage and transportation pilots. These pipeline projects must exceed 20,000 Nm3 of capacity. This requirement ensures that they can efficiently and safely use hydrogen for these purposes today and for years to come. In the case of liquefaction plants, there’s an economic threshold whereby plants need to process a minimum of five tonnes per day. This requirement shows the initiative’s seriousness about advancing efficient hydrogen use.
Long-term energy storage pilots are an essential step in this innovation process. They are necessary to reach 1 megawatt output and maintain full load generation for a minimum of four continuous hours. This need for reliability highlights the crucial role of energy storage technologies that can be inherently reliable as China undergoes its hydrogen-based transformation to a powerhouse economy.
End-Use Applications and Power Generation
The end-use applications category includes four separate pilots, each researching a different approach to using hydrogen as a clean energy solution in various sectors. Key requirements for power generation pilots. Hydrogen or ammonia blended fuel gas turbines should be able to operate with a capacity as low as 10 megawatts, consuming a mix of 15% hydrogen or ammonia. Any coal-fired boiler greater than 300 megawatts capacity must operate on a 10% hydrogen or ammonia blend.
Each fuel cell project has to be at least 0.5 megawatts. This key provision strengthens the workability and flexibility of hydrogen technology to meet a broad array of use cases. China is methodically embedding hydrogen into its energy systems for strategic advantage. These initiatives help foster innovative solutions that advance clean energy.
