Rolls-Royce to launch Mtu marine engines in 2023 for sustainable fuel
Rolls-Royce is taking another step on the path to climate-neutral shipping with the approval of its 2000 Series and 4000 Series mtu marine diesel engines in 2023 for use with sustainable fuels. After successful bench and field testing, Rolls-Royce’s Power Systems business unit will gradually certify its mtu 2000 and 4000 series marine engines for EN15940 synthetic diesel fuels from early 2023. These fuels include sustainable fuels BtL (Biomass to Liquid), HVO (Hydrotreatment Vegetable Oil/renewable diesel) and PtL (Power to Liquid) such as e-diesel. They can all replace conventional diesel fuel, which is made from fossil oil, without any adjustments to these engines. Rolls Royce last year
is committed to proving that the 2000 and 4000 series, its most popular production engines, can be run on sustainable fuels.
“There is already a lot of interest from many marine industry customers who want to improve their carbon footprint, especially with HVO,” explained Denise Kurtulus, Vice President Global Marine at Rolls-Royce Power Systems. . “Results from pilot customers show significant reductions in greenhouse gas, nitrogen oxide and particulate emissions by using HVO instead of fossil diesel.” Engines are used, for example, in ferries, work boats and large yachts.
41,000 hours with HVO: mtu engines at the Golden Gate Ferry with convincing performance
“Since 2019, we have successfully tested the use of HVO (renewable diesel) with mtu engines in six ferries in our fleet,” said Jim Swindler, general manager of Golden Gate Ferry in San Francisco, California. Testing over 41,000 hours of operation has confirmed that when HVO is used, mtu engines perform as remarkably well as diesel – in terms of maximum power, load acceptance and fuel consumption. “And the visible smoke that was seen on the dock with conventional diesel has been reduced with the switch to HVO.” Four other shipping companies in the United States are currently testing the use of HVO with their mtu engines. HVO is an alternative fuel, which means that the infrastructure of the previous diesel system can be used as is for its use, and no hardware or software modifications to the engine are required.
The use of HVO significantly reduces CO2, nitrogen oxide and particulate emissions
Waste vegetable and animal fats and waste vegetable oils can be used as feedstocks for HVO, which are converted into hydrocarbons by means of a catalytic reaction with the addition of hydrogen. Through this process, vegetable fats and oils are adapted in their properties to diesel fuel and can supplement it as an additive or completely replace it. The benefits of HVO are clean combustion with reductions in particulate emissions of up to 80%, nitrogen oxide emissions by an average of 8% and (depending on manufacturing process and raw material) CO2 emissions up to 90% compared to fossil diesel. Because HVO fuel is produced from renewable raw materials, its production, transportation and combustion only generates about as much greenhouse gas as what was absorbed by plants during the growth of the biomass.
Target: 35% greenhouse gas reduction with new mtu fuels and technologies by 2030
Rolls-Royce announced in 2021, as part of its sustainability program, that it would realign its product portfolio so that by 2030 new fuels and new mtu technologies can save 35% of gas emissions greenhouse effect compared to 2019. “We have realigned our offer for the maritime industry to actively support ship operators in their journey to Net Zero”, explained Denise Kurtulus. The company is currently working on methanol engines and fuel cell systems for shipping and developing electrolysers to produce green hydrogen.
