Marine
The marine industry stands in the center of international trade and commerce. However, the use of traditional heavy fuel oil as marine fuel has left a significant environmental footprint in the industry due to its association with high GHG emissions. The vast adoption of alternative fuels for use in seagoing vessels currently stands as a key priority to decarbonise this sector.

The use of alternative replacement marine fuels have significant potential to reduce the sector’s greenhouse gas emissions. However, widespread adoption will require overcoming obstacles related to infrastructure, fuel availability, and cost-effectiveness.
Our Focus Areas
Biofuels
PROS:
- Biofuels can be used as a drop-in fuel without major changes to existing infrastructure
CONS:
- Limited feedstock supply
LNG
PROS:
- Benefit from low infrastructure investment costs as they can be used as drop-in fuels and delivered via existing LNG bunkering infrastructure
- LNG vessels comprise of the largest share of the global alternative-fuelled vessel fleet
CONS:
- Methane slip, which may offset the benefits of LNG consumption compared to traditional fossil fuels.
Green Ammonia
PROS:
- Green ammonia offers a greater carbon emission reduction potential from a well-to-wake basis compared to grey LNG
CONS:
- Adoption as a bunker fuel is logistically challenged as it require significant infrastructure investment across the entire supply chain.
- Low energy density.
Green Methanol
PROS:
- Green methanol offers a greater carbon emission reduction potential from a well-to-wake basis compared to grey LNG
CONS:
- Existing green methanol production remains limited
Market Share Size
In a net zero emissions (NZE) scenario, the market share size of alternative maritime fuels increase significantly from 2030, and eventually taking a majority share over traditional fuels by 2050.
