Marine Gensets Industry News

  • In April 2026, Mitsubishi Heavy Industries announced it has been granted Approval in Principle by Class NK for a methane oxidation catalyst system for LNG‑fueled marine engines, a technology directly applicable to next‑generation marine gensets fueled by gas. The system will be designed to reduce dramatically methane slip from LNG engines, which is one of the most important environmental issues with gas-fired marine generator sets, and thus enhance overall generator set emissions performance and support ship operators to meet increasingly tightened IMO decarbonization goals. The innovation comes on the heels of a trend in the marine genset market of incorporating emissions‑control equipment and fuel flexibility into auxiliary power systems to make gensets as much a part of low-carbon shipping operations as they are a part of the ships' power systems.

  • In November 2025, Wärtsilä received a repeat contract to supply an integrated hybrid propulsion system for a series of bulk carrier vessels under construction for Aasen Shipping, which is a close follow-up to today's modern marine genset applications. This system features an onboard 25 kW company engine, which can be used as a primary power source or as an auxiliary power source, as well as a DC hub, a 620 kWh battery energy storage unit and advanced energy management systems for optimizing energy use on board. This hybrid system provides vessels with better efficiency in various operational scenarios, which should help to lower fuel consumption and emissions, and be future-proof for the switch to low and zero carbon fuels. Ongoing shift toward electrified and low-emission auxiliary power solutions in the maritime sector, the project emphasizes its approach towards the integration of gensets with hybrid and battery systems.
