Volvo Penta has launched a portfolio of new variable-speed marine generator sets. The range – designed for hybrid and electric applications – will enable vessels to be built with smaller battery packs that can be charged during operations. This makes the transition to cleaner forms of propulsion more cost-efficient.
Volvo Penta’s latest generator sets are already being utilized in real-world applications and range from the D8 model with 190kWe up to the more powerful D16 with 454kWe. To further improve its sustainability credentials, the company’s diesel engines are capable of running on Hydrotreated Vegetable Oil (HVO) 100 fuel, a renewable diesel fuel alternative that can reduce fossil CO2 emissions by up to 90%.
Typically, a modular series of variable-speed marine generator sets are installed with or without accompanying battery packs to power electric forms of propulsion. Volvo Penta’s direct current (DC) grid system can be upgraded easily by adding alternative forms of power. It also weighs less due to fewer components. The modular installation setup enables fewer engines to deliver the necessary power, allowing the marine generator sets to run at the most efficient speed.
Each of the variable-speed marine generator sets meets the latest IMO Tier III regulations and is water-cooled to ensure less noise and more efficiency for vessels.
“By making our Volvo Penta variable-speed marine generator sets more widely available, it takes us further forward in our journey toward more electric and fuel-cell propulsion for the marine industry,” said Johan Inden, head of marine business at Volvo Penta. “Now, more vessels will be able to install modular hybrid propulsion systems ready to be adapted to future energy choices, meanwhile delivering important sustainability and fuel-efficiency gains from day one.”
