Rolls-Royce and Flanders Electric have agreed to develop a retrofit solution for hybridizing mining-class haul trucks with mtu engines, batteries and hybrid control systems, and Flanders drive train solutions. The two companies have signed a Memorandum of Understanding enabling them to offer a scalable retrofit kit for hybridizing mining trucks in a wide range of mining applications.
With its brand mtu, Rolls-Royce business unit Power Systems is a leading provider of advanced integrated and sustainable power solutions for a wide variety of applications, including mining equipment. Flanders is an industry leader in the development and sale of electric motors and generator systems, as well as automation and control systems for heavy industrial applications. The companies said they plan to offer customers hybrid solutions that aim to save fuel and reduce the CO2 footprint of mining trucks as well as optimizing vehicle power performance and efficiency, enabling more climate-friendly and safer mining operations.
“Improving our customers’ operations, lowering their costs while enhancing their energy footprint, is a win for the mining industry and for the environment as a whole,” Flanders Chairman and CEO John Oliver said. “We are excited to partner with Rolls-Royce Power Systems to deliver an industry leading hybrid power solution that will help our customers achieve their energy or carbon reduction goals.”
“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,” said Scott Woodruff, vice president for mining and oil and gas at Rolls-Royce Power Systems. “Together we will offer our customers integrated, future-oriented, hybrid solutions.”
The haul truck hybrid concept recovers braking energy using the mtu EnergyPack battery system. This energy is then fed back to power the wheel motors, allowing the diesel engine to be downsized. The smaller engine reduces fuel consumption and CO2 emissions by up to 30%, helping mining customers to achieve their emissions reduction targets, while optimizing their operations. The hybrid concept also includes the DC/DC converters, which interface the battery system with the DC link of the truck. The system is highly modular and scalable.
