Marine Propulsion and Auxiliary Power Market Outlook:
Marine Propulsion and Auxiliary Power Market size was over USD 11.59 billion in 2025 and is projected to reach USD 35.36 billion by 2035, witnessing around 11.8% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of marine propulsion and auxiliary power is evaluated at USD 12.82 billion.
The shipping industry is committed to cutting back on CO2 emissions and fuel use. In order to comply with strict energy restrictions, they are implementing engineering adjustments and implementing renewable and alternative energy sources. The International Maritime Organization (IMO) will implement new rules in January 2020 that will restrict the sulfur content of marine fuels used by ships in international seas to 0.5% by weight. This represents a decrease from the prior worldwide cap of 3.5% established in 2012. Therefore, it is expected that the imposition of strict energy requirements will boost the market value of auxiliary power and marine propulsion in the coming years.
The increase in the marine industry's use of fuel-efficient technologies and the long-term growth of global trade and commerce depends on the marine and shipping sectors is set to boost the marine propulsion and auxiliary power market growth
