Hybrid offerings

Northern Lights Hybrid Electric Power Generation and Propulsion Systems use both electric motors and generators combined with internal combustion engines in order to increase vessel performance, comfort and reliability. Hybrid electric systems have the potential to significantly increase vessel fuel efficiency and to reduce emissions in order to comply with ever increasing green house emissions regulation while reducing cost. This makes hybrid electric systems more sustainable in today’s sophisticated market place.
