3500/42M-SIL2-09-05 Under the “double carbon” goal, the metallurgical industry, as one of the industries with high energy consumption and high emissions, is facing unprecedented pressure to reduce carbon emissions, and the industry needs to change from a high carbon process to a low carbon process, and increase the application of clean and low-carbon energy to replace coal. Among them, especially in the steel industry, in order to achieve near-zero emissions, steel enterprises in addition to actively adopt low-carbon zero-carbon fuel solutions, but also need to accelerate digital transformation, improve the overall energy efficiency and operational efficiency; At the same time, companies must combine transformative technologies such as hydrogen-based steelmaking, iron ore electrolysis, and carbon capture, utilization and storage (CCUS) to achieve efficient decarbonization
Hydrogen energy is a kind of clean energy that can be prepared and transported. Green hydrogen (GH2) produced by renewable energy helps to build a clean, low-carbon, safe and efficient energy system. At present, China is actively exploring the application space of hydrogen energy to replace fossil energy in metallurgy, chemical industry and other industrial fields. The National Development and Reform Commission and the National Energy Administration jointly issued the “Medium and Long-Term Plan for the Development of Hydrogen Energy Industry (2021-2033500/42M-SIL2-09-05 5)”, which proposed that the exploration of hydrogen metallurgy demonstration application will be one of the innovative application demonstration projects of hydrogen energy industry during the “14th Five-Year Plan” period.
The transition to green hydrogen fuel is undoubtedly one of the effective means to promote the “carbon reduction difficult” industries such as steelmaking to carbon neutrality. However, at present, the raw materials of hydrogen energy preparation in China are mainly fossil fuels, and green hydrogen preparation faces problems such as high production cost, incomplete special infrastructure, and large energy loss, and there is still a certain distance in large-scale commercial application. Schneider Electric believes that hydrogen production enterprises need to strengthen the integration capacity of renewable energy in an all-round way, to prepare green hydrogen with lower cost, higher efficiency and larger production scale, and help more enterprises in high-energy industries to implement carbon emission reduction. In this process, the digital operation capability of the green hydrogen plant becomes the key to high-quality hydrogen production.
Digital empowerment, efficient integration of green hydrogen preparation process
Based on the real needs of the industry, Schneider Electric provides green hydrogen 3500/42M-SIL2-09-05 integrated design and operational solutions to digitally help companies reduce their carbon footprint, reduce total capital and operating expenses, and maximize the efficiency of green hydrogen integration. Specifically, the full life cycle of “design engineering construction to production operation and maintenance” of green hydrogen plants is mainly enabled from the following four dimensions:
1. Integrated design and simulation: Green hydrogen preparation is a power-intensive production process, and its energy system design requires the ability to simulate and model power and process.
Relying on Schneider Electric AVEVA Pro/II & Process Simulation software and AVEVA E3D Design software, Green Hydrogen Plant can build digital twins of process production processes based on production process mechanism, and conduct integrated modeling of various designs and scenarios. With variables such as weather, equipment, processes, fluctuations in offtake demand and local infrastructure (current and future), we optimize the overall design from design to construction to production by simulating equipment attributes and online process behavior, maximizing return on investment and minimizing risk. Among them, digital twin solutions based on the integration of analog simulation with factory 3D design tools help to:
Achieve seamless transition of each link and reduce the construction time;
Reduce human error and the risk of rework resulting from it;
Integrate process and power design to build an engineering digital twin base;
Integrated energy management and process simulation to achieve end-to-end coupling and comprehensive analysis of process equipment;
Improve overall performance and ensure design integrity between process equipment and distribution equipment.
