Sustainable Marine Solutions

The maritime industry is on course to becoming greener.

Responsible for 2.5% of global CO2 emissions, growing concerns and regulations are putting pressure on the shipping industry to find cleaner fuel alternatives.

At Rolls-Royce, we’re enabling a greener maritime industry through new mtu marine solutions for propulsion, automation and service. Our expert teams are working with customers and partners to examine the best marine propulsion solution – from fuel infrastructure, drive profiles of ships to the propulsion system and its integration in the vessel.

Engines ready for the energy transition

Our Series 2000 and Series 4000 mtu marine diesel engines are on the road to achieving climate neutrality. Following successful trials spanning thousands of hours, the engines are on course to achieve approval for use with synthetic fuels such as BtL (Biomass to Liquid), HVO (Hydrotreated Vegetable Oil/renewable diesel) and PtL (Power to Liquid) such as e-diesel. What’s more, sustainable fuels can be used with zero modifications to the engines.

Future marine systems

While e-fuels – which are produced from renewable energy sources – can be converted into propulsion power in ways that are climate-neutral, finding the right future propulsion solutions for the maritime industry is a challenge.

At Rolls-Royce, we're dedicated to exploring the possibilities of sustainable propulsion, from adapting our existing products for the use of sustainably produced fuels to investing in innovative new systems that could help to achieve a carbon-neutral future.

The benefits of methanol

Methanol has a high energy density compared to other sustainable fuels, and its liquid state means it's easy to store and makes use of existing infrastructure. Unlike ammonia, methanol is environmentally safe, and its combustion can be shown to be climate neutral.

Methanol can also be used not just in diesel and spark-ignition combustion engines, but in conjunction with zero-emission fuel cells. This is an especially attractive proposition aboard ships where space is a premium commodity or not available at all.

Hybrid systems

Alongside new and additional fuel requirements, the architecture of propulsion systems is also changing. Vessels powered solely by combustion engines are becoming less commonplace, while hybrid systems are now more popular.

At Rolls-Royce, we’re focused on developing hybrid systems that can use combustion engines and fuel cells.
