Volvo Penta has launched a new range of variable speed marine generator sets – a key enabler for electric propulsion for marine vessels.

The range of variable speed marine generator sets allows shipyards to install hybrid-electric modular propulsion systems. This enables operators to invest in new vessels knowing that they are ready for emerging alternative energy sources.

The variable speed marine generator sets make it possible to have smaller battery banks and charge them while on the move. This technology is already being used by the Swedish Transport Administration and MHO-Co.

Volvo Penta is offering the range with models starting from D8, 190 kWe and running up to 545 KWe for the D16. Also, all Volvo Penta diesel engines can run on HVO 100 fuel, instead of standard diesel, to reduce fossil CO2 emissions by up to 90 per cent.

A typical installation sees a modular series of variable speed marine generator sets installed to power electric drives with or without battery packs. This DC grid system is easy to upgrade with alternative power sources and has fewer components and weighs less – especially when compared to batteries as the sole energy carrier.

The new Volvo Penta variable speed marine generator sets are also the most compact to meet the latest IMO Tier III regulations.  They’re water-cooled, which means less noise and more efficiency too.
