Rolls-Royce and Flanders partner on hybrid retrofit solution

Engine developer Rolls-Royce and electrical motor company Flanders Electric plan to partner on development of a retrofit solution for hybridising mining trucks with mtu engines.

The mining truck hybrid concept would involve braking energy being transferred into storage in the mtu EnergyPack battery system.

Energy is then fed back to power the wheel motors, allowing the diesel engine to be downsized - reduces fuel consumption and C02 emissions by up to 30%.

The hybrid concept also includes the DC/DC converters which interface the battery system with the DC link of the truck. 

Scott Woodruff, Vice President for Mining and Oil & Gas at Rolls-Royce Power Systems, said: "We are excited to shape the mining industry's sustainable future together with Flanders and further leverage our advanced hybrid technologies, which are already proven in the rail industry. Together we will offer our customers integrated, future-oriented, hybrid solutions." 

The news of the partnership comes a day after Power Systems announced it has been developing a hybrid haul truck mtu concept that it plans to exhibit at Minexpo 2021.

The company said the concept features a 12V 2000 mining engine, together with an mtu EnergyPack battery system - as a result, it reduces emissions by up to 30%.

Rolls-Royce also said it had also simulated operations with a haul truck using a 16V 2000 engine  with an output of 1163 KW ,  as a replacement for a mtu 16V 4000 engine, with an output of 1865 KW.
