Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On July 26, 2025, the world’s largest single-unit green ammonia production facility – the **Dian Tou Daan Wind-Solar Green Hydrogen to Ammonia Integration Demonstration Project** – was officially put into operation in Daan, Jilin. The project employs four world-first innovative technologies, including the world’s largest DC microgrid-based hydrogen production system and the world’s largest solid-state hydrogen storage system. The 48,000 Nm³ solid hydrogen storage system, jointly developed and overall contracted by Shanghai HETO Engineering Co., Ltd. (HOTO) and CECC Research (Xuzhou) Hydrogen Energy Technology Co., Ltd., has successfully achieved the functions of hydrogen absorption, storage, and release. The solid hydrogen storage technology used in this project enables hydrogen absorption and release at temperatures below 60°C, overcoming the limitation of conventional solid hydrogen storage technologies regarding hydrogen release at high temperatures. This expands the application possibilities of solid hydrogen storage technology. It features a significantly reduced footprint, greater safety in hydrogen storage, and lower overall costs, thus opening up new avenues for hydrogen storage. This large-scale demonstration serves not only as a test of the maturity of solid-state hydrogen storage technology but also as a key driver for overcoming the \"last mile\" challenge in the application of hydrogen energy. By verifying its safety, cost-effectiveness, and suitability for various applications, it paves the way for the widespread commercial use of solid-state hydrogen storage technology, holding transformative implications especially for sectors such as transportation and energy storage. HOTO has been dedicated to the development and application of engineering technologies in the field of renewable energy. It has completed the world’s first large-scale green hydrogen demonstration project, the green hydrogen supply project for the Beijing Winter Olympics, as well as the world’s largest green hydrogen-ammonia project… The successful commissioning of this world’s largest solid-state hydrogen storage demonstration project represents another breakthrough for HOTO in the field of renewable energy development and utilization.
As a **demonstration project for clean and low-carbon hydrogen energy as well as one of the 100 key projects in the strategic emerging industries sector, the project commenced construction in May 2023. It features an installed capacity of 800 megawatts in new energy sources (700 megawatts from wind power and 100 megawatts from solar power), with the ability to produce 32,000 tons of green hydrogen per year, as well as 180,000 tons of green ammonia from that green hydrogen. Once in operation, it will reduce carbon emissions by about 650,000 tons per year and save around 230,000 tons of standard coal, which is equivalent to offsetting the carbon emissions generated by nearly 500,000 ordinary households’ annual electricity consumption. The project innovatively adopts a full-industry-chain design approach that involves using green hydrogen to consume green electricity, and using green ammonia to consume green hydrogen, as well as integrating the power generation, transmission, load, and storage systems. It has yielded 1 invention patent and 33 utility model patents, and numerous significant technical breakthroughs have been achieved. Its most notable achievements include four world records: it is the largest project of its kind for the one-time production of green ammonia, with an annual production capacity of 180,000 tons of ammonia. This project has successfully established a complete industrial chain that goes from electricity to hydrogen and then to ammonia, providing a new pathway for the on-site conversion of renewable energy into useful products ； The world’s largest-scale hydrogen production via the combination of alkaline and PEM electrolysis: hydrogen production using alkaline methods at 36,000 cubic meters per hour and hydrogen production using PEM methods at 9,600 cubic meters per hour – these two technologies are integrated together, offering both scalability and flexibility and thus creating a combined advantage ； The world’s largest direct-current microgrid-based hydrogen production facility – overcoming the key technical challenges related to direct-current off-grid hydrogen production as well as the issue of local manufacturing of the necessary equipment; enabling hydrogen production through direct use of 40 megawatts of renewable energy, and exploring new models for wind and solar-powered off-grid hydrogen production ； The world’s largest solid-state hydrogen storage facility, featuring 48,000 cubic meters of such storage capacity, was built to demonstrate the feasibility of solid-state hydrogen storage in the production of hydrogen from renewable sources, thereby helping to overcome the challenges associated with hydrogen storage.
