(Shanghai, China) – Technology company Envision Energy is participating in the AEA ammonia certification system. The project, developed by the US-based Ammonia Energy Association (AEA) in conjunction with the US institute MiQ, which specializes in methane certification, launched in October 2025 and is now entering its pilot phase. The AEA now has more than 270 members – a veritable "who's who" of the global hydrogen, ammonia, and energy industries.

Certification is a voluntary system that allows producers, traders, and consumers to verify environmental attributes such as the carbon footprint and origin of the energy carrier using independently verified data. An ammonia registry is intended to ensure transparency and traceability along the entire supply chain, from certificate issuance and trading to decommissioning. Envision uses the "book-and-claim" model: This enables trading of environmental attributes without physical transport and decoupled from the physical supply chain; comparable to models in the renewable energy sector and for SAF (Sustainable Aviation Fuel). "This allows our customers to decarbonize their operations regardless of their geographical proximity to our production centers, accelerating the adoption of green ammonia as a bankable, carbon-neutral commodity," says Frank Yu, Senior Vice President of Envision Energy.

In March 2026, Envision completed the first end-to-end commercial shipment of green ammonia from its "Net Zero Industrial Park" in Chifeng, China, to the port of Ulsan, South Korea, validating the entire value chain, including international maritime logistics. The company had commissioned this world's largest production facility for green hydrogen and ammonia, with an annual capacity of 320.000 tons, in July 2025 ( more information here ).
In Ulsan, at the beginning of April 2026, the South Korean chemical company Lotte Fine Chemical Co. Ltd. used the ammonia from China to fill its new mid-sized dual-fuel gas tanker, the "Antwerpen." The 600 tons of fuel will be used for sea trials off the South Korean coast, although the vessel has already completed initial voyages using conventional diesel. Developed by a consortium of HHI-EMD, Wärtsilä Gas Solutions, WinGD, and Lloyd's Register, and built by HD Hyundai Heavy Industries, it had only recently been commissioned. At the end of May, it will be officially handed over to the Belgian gas transport specialist Exmar Group and put into commercial operation.
In July 2025, Envision commissioned the world's largest production plant for green hydrogen and ammonia, with an annual capacity of 320.000 tons. Plans are in place to expand the capacity to 1,5 million tons, which, according to the company, will achieve price parity with gray ammonia. © Envision Energy
Utilizing its existing (and Asia's largest) ammonia terminal near the Port of Ulsan, Lotte Fine Chemical became South Korea's first registered supplier of ammonia as a marine fuel in 2025. In May 2025, the city of Ulsan was declared an "Ammonia Bunkering Regulatory Free Zone," reducing regulations for the development and demonstration of ammonia bunkering in and around the port. Support was provided by the Korean Ministry of Oceans and Fisheries, the Port Authority, and the Korean Register. These institutions assisted with tasks such as registering ammonia fuel suppliers, developing safety management guidelines, and establishing safety standards.
