1 Global Ship Exhaust Gas Scrubber Market Size (Value) and CAGR (2024-2033)
In 2024, the global Ship Exhaust Gas Scrubber market was valued at USD 4160.9 million, with a CAGR of 23.2% from 2024 to 2033.
Ship Exhaust Gas Scrubber is a device installed onboard marine vessels that, quite literally, “scrubs” harmful sulfur oxides from exhaust gases. Ship Exhaust Gas Scrubber exhaust gas cleaning reduces Sulphur (SO2) and particulate emissions from ship engines, generators, and boilers. Scrubbers enable vessels to consume cheaper, high-sulfur fuel oil (HSFO) while still complying with mandated emissions levels. Vessels with scrubbing technology installed will be able to consume high-sulfur fuel at a significant discount to low-sulfur fuel.

2 Ship Exhaust Gas Scrubber Market Drivers
The continuous advancement in scrubber technology is a primary driver for the market. Modern scrubbers are becoming more efficient and reliable, with innovations such as hybrid systems that can operate in both open-loop and closed-loop modes. These hybrid systems offer flexibility and adaptability to different operational conditions, making them highly attractive to ship owners. For example, Wärtsilä’s IQ Series scrubber is designed to be lighter and smaller, reducing the space required on vessels while maintaining high efficiency. Such technological advancements not only enhance the performance of scrubbers but also reduce operational costs, making them a more viable option for compliance with environmental regulations.
Stringent environmental regulations imposed by international bodies such as the International Maritime Organization (IMO) are a major driving force. The IMO’s sulfur cap regulations, which require ships to use low-sulfur fuel or install exhaust gas cleaning systems, have significantly increased the demand for scrubbers. Since January 1, 2020, ships sailing globally must use fuel with a sulfur content of less than 0.5% m/m, or they must install approved exhaust gas treatment systems. This regulatory push has led to a surge in scrubber installations, as it provides a cost-effective solution for compliance compared to switching to low-sulfur fuels, which are often more expensive.
The economic benefits of installing scrubbers are another significant driver. By allowing ships to continue using high-sulfur fuel oil (HSFO), scrubbers help ship owners save on fuel costs. The price differential between HSFO and low-sulfur fuel can be substantial, making the investment in scrubber technology a financially attractive option. Additionally, the return on investment (ROI) for scrubbers is relatively short, often within 1-2 years for vessels operating in Emission Control Areas (ECAs). This financial incentive encourages more ship owners to invest in scrubber technology.
3 Ship Exhaust Gas Scrubber Market Challenges
One of the most significant challenges is the high upfront cost associated with installing scrubbers. The equipment itself can cost between $1 million and $5 million per vessel, with additional labor and installation costs adding to the total expense. This high initial investment can be a barrier for many ship owners, especially those operating older vessels or smaller fleets. Moreover, the installation process can be complex and time-consuming, often requiring the vessel to be out of service for extended periods, leading to lost revenue.
While scrubbers are effective at removing sulfur oxides (SOx) from exhaust gases, they have limitations in addressing other harmful emissions such as nitrogen oxides (NOx), particulate matter (PM), and carbon dioxide (CO2). This limitation means that scrubbers may not be a comprehensive solution for future emissions regulations, which are expected to become even more stringent. The need to address these other pollutants could require additional investments in complementary technologies, adding to the overall cost and complexity of compliance.
The process of scrubbing sulfur oxides from exhaust gases generates waste, which must be properly disposed of. This waste, often in the form of sludge, can pose environmental risks if not managed correctly. The disposal of this waste can be challenging and costly, adding to the operational burden of using scrubbers. Additionally, concerns about the overall carbon footprint of scrubbers, including the energy required to operate them and the potential for increased CO2 emissions, are also areas of concern that need to be addressed.
4 Global Ship Exhaust Gas Scrubber Market Size and Share by Type in 2024
Open Loop Scrubbers are the most common type of exhaust gas scrubbers used in the maritime industry. These systems utilize seawater to neutralize sulfur oxides (SOx) in exhaust gases. The seawater, which is naturally alkaline, reacts with the sulfur oxides to form harmless byproducts that are then discharged back into the sea. This type of scrubber is highly effective and relatively simple in design, making it a popular choice for many ship operators.
In 2024, the market value for Open Loop Scrubbers is estimated to be $2,174.8 million. This represents a significant portion of the total market, highlighting the widespread adoption of this technology. Open Loop Scrubbers are particularly advantageous for vessels operating in open seas where there is an abundant supply of seawater.
Closed Loop Scrubbers operate by treating exhaust gases with freshwater mixed with alkaline chemicals, typically sodium hydroxide (NaOH). This process converts sulfur oxides into harmless sodium sulfate, which is then removed from the system. Unlike Open Loop Scrubbers, Closed Loop Scrubbers recycle the wash water, adding fresh water only as needed to compensate for evaporation and blowdown. This closed-loop system ensures that no harmful substances are discharged into the sea, making it an environmentally friendly option.
The market value for Closed Loop Scrubbers in 2024 is projected to be $126.1 million. While this is a smaller segment compared to Open Loop Scrubbers, the demand for Closed Loop Scrubbers is growing due to their ability to operate in any water condition, including those with low alkalinity.
Hybrid Scrubbers combine the benefits of both Open Loop and Closed Loop systems, offering the flexibility to switch between seawater and freshwater-based operations. This dual functionality allows vessels to optimize their scrubber operations based on the specific conditions of their voyage, ensuring compliance with environmental regulations while minimizing operational costs.
In 2024, the market value for Hybrid Scrubbers is expected to reach $1,860.1 million. This significant market share reflects the growing preference for Hybrid Scrubbers due to their adaptability and efficiency.
