Do you believe ammonia-powered shipping is a viable solution for reducing global carbon emissions?

Höegh Autoliners has successfully completed factory acceptance testing for its new ammonia-powered dual-fuel engine at HD Hyundai Heavy Industries in South Korea. The milestone marks a key step in equipping its upcoming 9,100-CEU capacity carrier to support future zero-emission shipping operations.

Why it matters

Ammonia serves as a critical potential fuel source for the maritime industry to achieve carbon-neutral logistics without relying on fossil fuels. This engine advancement provides a tangible pathway for scaling zero-emission operations within the global car transport sector.

The B&W 7S60ME-LGIA engine is a two-stroke, slow-speed ammonia unit designed for 9,100-CEU pure car and truck carriers. Following this success, the firm plans to install the same model on four additional upcoming Aurora-class vessels.

The players

Höegh Autoliners

This Norwegian shipping company specializes in the global transportation of automobiles and heavy machinery.

HD Hyundai Heavy Industries

Headquartered in South Korea, this massive conglomerate is one of the world's largest shipbuilding and heavy equipment manufacturers.

China Merchants Heavy Industry

This Chinese state-owned enterprise operates major shipbuilding facilities and provides industrial engineering solutions for global maritime clients.

The details

The engine utilizes Liquid Gas Injection Ammonia technology to power large-scale car carriers currently under construction at China Merchants Heavy Industry in Jiangsu. These vessels are being engineered specifically to accommodate the hardware for zero-emission maritime transit.

Timeline

  1. Factory acceptance testing was completed in September 2026.

  2. The initial vessel is scheduled for launch in 2027.

Roadmap

This development follows the International Maritime Organization's 2023 Greenhouse Gas Strategy, which mandates significant industry-wide emissions reductions. The adoption of ammonia-fueled propulsion signals a major technological pivot for international logistics, positioning carriers to move away from conventional heavy fuel oil.

The adoption of zero-emission engine technology may eventually reduce the carbon footprint associated with the international transport of new vehicles. While daily buyers will not notice immediate differences, these structural changes are essential for lowering the total environmental cost of the global automotive supply chain.

The takeaway

Advancements in ammonia-powered shipping demonstrate that heavy-duty maritime transport is prioritizing long-term sustainability to meet global climate mandates. Industry observers should track the 2027 vessel launch as a benchmark for the viability of alternative clean fuels at sea.
