Fuel flexibility may be a key driver for recent developments in gensets, but the perennial goals of lowering CapEx and OpEx remain.Fuel flexibility is one of the pillars of decarbonization that is being embraced by genset OEMs. Fuel efficiency, a second pillar, goes hand in hand with that because new fuels will be more expensive, but these concerns come in addition to the on-going drive to reduce CapEx and OpEx for shipowners.MAN Energy Solutions introduced its auxiliary MAN 35/44DF CD engine in June 2023. It is designed to be future-proof and will be ready for methanol operation by 2026.
