China Completes World's First Green Ammonia Ship Refueling

The shipping industry just took its biggest leap toward clean oceans in decades, and it happened in the waters off Zhoushan, China.

On October 13, 2026, a converted vessel called Shenghang Yongle pumped 1,000 metric tonnes of green ammonia into the Mineral Europa, a massive 210,000-tonne bulk carrier. It marked the world's first commercial ship-to-ship refueling using ammonia as fuel, moving zero-carbon shipping from laboratory dreams to working reality.

The ammonia wasn't just any fuel. It came from a facility in Jilin Province powered entirely by wind and solar energy, making it truly zero-carbon from creation to consumption.

The Shenghang Yongle started life as a regular ammonia carrier with a 5,547 cubic meter capacity. Jiangsu Andefu Energy Development led the conversion work, transforming the workhorse vessel into a specialized refueling station that can operate while both ships are at sea. The China Classification Society issued the world's first ammonia bunkering certificate for the project.

The technical challenges weren't small. Ammonia requires handling at temperatures as low as -48°C, poses toxicity risks, and demands completely new safety protocols. Engineers rewrote emergency response procedures and installed specialized leak detection systems to make ship-to-ship transfers safe.

Belgium's CMB.TECH owns the Mineral Europa, which received the historic refueling. The company is simultaneously building an entire fleet of ammonia-powered vessels and securing Chinese green ammonia supplies for the future.

The Ripple Effect spreads far beyond one successful refueling. Shipping accounts for nearly 3% of global greenhouse gas emissions, and the industry has struggled to find clean alternatives to diesel that actually work at sea. This breakthrough proves ammonia can slash emissions by over 90% in real commercial operations, not just controlled tests.

The Nanjing Maritime Safety Administration plans to use lessons from this operation to create standardized supervision procedures for ammonia-fueled vessels. That regulatory framework will help other shipping companies adopt the technology faster.

Other pioneering ammonia bunkering projects are already underway in Singapore, supported by companies like ITOCHU and MOL. The race to clean up one of the world's dirtiest industries just shifted into high gear.

The conversion of an existing vessel, rather than building from scratch, shows the transition can happen faster and cheaper than many experts predicted. Thousands of similar carriers could potentially be retrofitted using the same approach.

China's "dual carbon" strategy aims to peak emissions before 2030 and achieve carbon neutrality by 2060, and maritime fuel is a crucial piece of that puzzle. This refueling demonstrates the country is turning policy promises into physical infrastructure.

The Shenghang Yongle now operates as the world's only commercial ammonia bunker vessel, but it won't hold that distinction for long.
