Global Shipping Green Transformation Analysis
The size of the global green shipping equipment and systems industry, based on revenue, has shown rapid growth in recent years, increasing from RMB 58 billion in 2018 to RMB 347 billion in 2024, with a compound annual growth rate of 34.6%.
Looking ahead, the market is expected to expand further, with the market size projected to reach RMB 170.2 billion by 2030, with a compound annual growth rate of 30.3% from 2024 to 2030. This strong growth is driven by increasingly stringent decarbonization regulations, accelerated fleet renewal demand, and growing shipowner focus on fuel efficiency, operational optimization, and long-term asset performance.
Subsector Industry Size of Ship Energy Efficiency Enhancement Systems
The size of the subsector industry focusing on ship energy efficiency enhancement systems, based on revenue, has increased from RMB 15 billion in 2018 to RMB 94 billion in 2024, primarily driven by the accelerated application of fuel-saving and optimization technologies on ships.
It is estimated that this subsector industry size will increase to RMB 674 billion by 2030, with a compound annual growth rate of 39.0%, becoming an important engine driving overall market growth. As shipowners increasingly focus on cost efficiency and performance optimization, this sector will continue to grow.
As the core product in the subsector industry of ship energy efficiency enhancement systems, the annual delivery volume of ship shaft generator systems increased from 143 sets in 2018 to 556 sets in 2024, and is expected to further rise to 2,540 sets by 2030.
Subsector Industry Size of Ship Exhaust Emission Control and Purification Systems
The size of the subsector industry focusing on ship exhaust emission control and purification systems, based on revenue, increased from RMB 20 billion in 2018 to RMB 31.4 billion in 2020, mainly driven by the International Maritime Organization's 2020 sulfur limit regulations, which prompted shipowners to install desulfurization systems to save fuel costs.
After the peak period of compliance installation, the market size for ship desulfurization systems dropped to RMB 13.6 billion in 2024. The market is expected to experience a new round of growth in 2026, attributed to the International Maritime Organization delaying the implementation milestone of the net zero framework to 2026, as well as the continued growth in demand for diversified emission control equipment and systems such as carbon capture technology.
With increasing global focus on achieving net zero emissions, it is estimated that the size of this subsector industry will reach RMB 36 billion by 2030, with a projected compound annual growth rate of 17.6% from 2024 to 2030.
As the largest component in the subsector industry of ship exhaust emission control and purification systems, the annual delivery volume of ship desulfurization systems increased from 149 sets in 2018 to 707 sets in 2024, and is expected to further rise to 1,444 sets by 2030.
