On November 24, the ammonia-hydrogen storage system at Qinghai Asia Silicon Polysilicon Co., Ltd., which was overseen by Tianhua Institute as the general contractor, was successfully commissioned in one attempt, with the purity of the liquid ammonia meeting the required standards. This achievement not only marks a significant breakthrough by Tianhua Institute in the industrial application of ammonia-based hydrogen storage technology, but also opens up new pathways for the cross-regional storage, transportation, and efficient utilization of green energy, thereby providing strong impetus for energy transformation in pursuit of the \"dual carbon\" goals. As an important carrier of clean energy, the challenges associated with the storage and transportation of hydrogen have long been a bottleneck restricting the large-scale development of the hydrogen industry. Ammonia-based hydrogen storage technology has become a key approach to solving this problem, thanks to its unique advantages such as high hydrogen storage density, low storage and transportation costs, strong safety, and compatibility with existing chemical infrastructure. The ammonia hydrogen storage system that was successfully operated this time uses hydrogen produced by electrolyzing water with renewable energy as raw material, and converts hydrogen energy into green liquid ammonia through advanced synthesis processes, thereby achieving efficient \"solidification\" and stable storage of hydrogen energy. The green liquid ammonia produced is not only a high-quality chemical raw material, but it can also serve as a carrier for \"liquid sunlight\"; by undergoing decomposition reactions when needed, it can release hydrogen to provide clean energy for industries, transportation, and other fields. As the global energy structure accelerates its transition toward cleaner and lower-carbon sources, the development and utilization of green energy have become a key area of competition in this industry. The successful operation of this device is a vivid example of responding to the **\"dual carbon\" strategy and putting the concept of green development into practice. Compared to ammonia production using traditional fossil fuels, this system relies on renewable energy for power throughout the entire process, resulting in zero carbon emissions during production. The green liquid ammonia produced eliminates environmental pollution at its source, achieving true cleanliness across the entire life cycle from start to finish. The implementation of this technical approach has effectively established a closed-loop industrial chain that connects \"renewable energy – hydrogen – green ammonia – hydrogen\", enabling unstable renewable sources such as wind and solar energy in remote areas to be converted into stable energy products that can be transported over long distances and deployed flexibly. This has greatly improved the efficiency and economic value of green energy utilization.
