ROLLS-ROYCE EXPANDS SUSTAINABLE MTU PRODUCT PORTFOLIO

ROLLS-ROYCE EXPANDS SUSTAINABLE MTU PRODUCT PORTFOLIO

Tuesday, September 7, 2021 

Rolls-Royce is launching a range of sustainable mtu propulsion solutions, targeted principally at the recreational market, and which include IMO Tier III compliant engines.

A Tier III version of the series 4000 has already been installed in large yachts, and this will be joined from April 2022 with mtu Series 2000 propulsion systems, equipped with exhaust gas aftertreatment.

Head of Yacht Competence Centre, Rolls-Royce’s Power Systems, La Spezia, Nicola Camuffo, said: “More new technologies will follow to help yacht manufacturers and operators achieve their sustainability goals and those of the Paris Climate Agreement.”

The new generation mtu 16V2000M97L engines will be available with an integrated exhaust aftertreatment system from April 2022, enabling vessels to sail in protected areas, for example in ECA zones such as the North American coast, the Caribbean and the North and Baltic Seas. The systems with SCR will significantly reduce particulate and nitrogen oxide emissions. Further engine variants of the mtu Series 2000 will gradually become available for IMO III operation.

From 2023, mtu plans to introduce hybrid propulsion systems for yachts in series production, initially with Series 2000 engines and variable electric power, which will cover a power range of about 1,000kW to 1,939kW per powertrain. In addition to the engines, the system includes electric motors, gearboxes, batteries, control and monitoring systems and other electronic components. Rolls-Royce's concept for an mtu series hybrid system comprises a modular building kit with standardised components and concepts for different vessel types and sizes.

Versions of both 2000 and 4000 series will be approved from 2023 for sustainable EN 15940 fuels such as e-diesel and second-generation biofuels including HVO (Hydrotreated Vegetable Oil), a biofuel that can be produced from waste in a CO2-neutral way, with low emissions and clean and efficient combustion. The company is additionally developing other new technologies such as fuel cell systems and methanol engines.

“There will be different propulsion concepts in the future, depending on the specific needs of yacht owners, shipyards and infrastructure. We are happy to exchange ideas with customers and other experts in order to jointly drive innovations forward, for example by means of pilot installations,” said Camuffo.
