A new study from engine manufacturer WinGD and renewable ammonia producer Envision has found that, with the right regulatory settings, low-carbon ammonia marine fuel can achieve cost parity with VLSFO and LNG at current prices, even before additional subsidies or rewards associated with zero-emission fuels are applied.
The study explores in-depth operations costs of bulk and container vessels shipping between Jinzhou in northeast China (a port where Envision is developing export and ammonia bunkering infrastructure) and Melbourne in Australia – one of the APAC region’s longest vessel routes. Using already-certified lifecycle fuel carbon intensities and current estimated bunkering pricing along the coast of China, by 2050, renewable ammonia fuel is projected to outperform LNG on a cost basis, with a predicted 5-6% lower lifecycle operating cost. The findings assume that a global regulatory regime like the IMO’s net-zero framework is adopted.
For the purposes of the analysis, fuel consumption, costs for NOX (and other) emissions abatement, and tank-to-wake emissions are all based on real-life performance of existing engines in WinGD’s portfolio: the ammonia-fueled X‑DF‑A, methanol-fuelled X‑DF‑M and LNG-fuelled X‑DF engines.
Through this joint study with WinGD, we have mapped a clear economic pathway for renewable fuels. By leveraging AI-driven optimisation at our Chifeng facility to harmonise renewable energy harvesting with fuel production, we have already reached a tipping point where green ammonia competes with VLSFO and LNG.
Green ammonia can be fully electrified and using green ammonia as bunkering fuel creates more certainty. As we further scale and refine these intelligent technologies, green ammonia will become the most practical and cost-effective choice for the next generation of shipping. This is the certainty we bring to an uncertain market.

This shows what it means to lead with innovation and collaboration. Using real fuel pricing, engine performance and emissions data, we show how green fuels can become commercially viable options for ship operators. With global policy on pause, now is the time for the industry to show how it can overcome the obstacles to decarbonisation using the fuels and technologies that already exist today.
