Partners to share performance data, R&D initiatives, training programs for sustainable propulsion upgrades

The new partnership will involve mutual sharing of system performance data, research & development initiatives, technical training, and the establishment of best practices for smooth installations. Providing climate friendly propulsion solutions will be key to lowering the climate footprint of the industry in a relatively short timeframe. The two partners see potential both in equipping existing yachts with environmentally friendly engines that also have particulate filters and SCR exhaust gas aftertreatment and in performing retrofits with hybrid drives.
'We want to be the proactive ambassadors for a clean and climate friendly superyacht operation and with the alternative fuel like HVO and others it's easy to take the first step', Rolls-Royce and MB92 stated.
Focus will initially be directed towards moving the fleet towards synthetic fuels such as BtL (Biomass to Liquid), HVO (Hydrotreated Vegetable Oil) and PtL (Power to Liquid) such as e-diesel, also known as EN15940 fuels. All of them can replace conventional diesel fuel in mtu Series 2000 and 4000 engines without any adjustments - most of them are already released for EN15940 use.
HVO provides an up to 90% decrease in emissions with no compromise on power output, providing the fuel is available. An existing yacht with engines that are not HVO-compatible can be refitted with modern mtu engines and thus be operated in a much more climate-friendly way than before. In parallel, the partners will look to integrate more advanced solutions as soon as possible in alignment with Rolls-Royce's ongoing R&D efforts on methanol-based solutions and other innovative alternatives.
Benefits of HVO
HVO is already available to buy.*
As HVO is a drop-in fuel, no adjustments are necessary for most diesel engines that are approved for HVO use. It is advisable however, to check elastomer seals regularly in the first four weeks following a switchover to HVO.*
The storage stability of pure HVO is substantially higher than that of pure Fatty Acid Methyl Ester (FAME) biodiesel, or HVO / FAME mixtures, and even fossil diesel fuel B7. That makes HVO particularly attractive to operators of standby power systems.*
Our tests have confirmed that there are usually no differences in the released mtu common rail engines in terms of their maximum power, load acceptance and fuel consumption - regardless of whether they are fuelled with HVO or diesel.*
Depending on the fuel manufacturing process, CO2 emissions fall by up to 90%. Particulate emissions fall by over 40%. Nitrogen oxide emissions are up to 8% lower.
