Global Marine Scrubber Market Growth 2025-2031

The global Marine Scrubber market size is predicted to grow from US$ 4444 million in 2025 to US$ 7553 million in 2031; it is expected to grow at a CAGR of 9.2% from 2025 to 2031.

The overwhelming majority of ships around the world operate using engines and boilers powered by heavy fuel oil. The resulting combustion exhaust gases that are emitted contain soot and sulfur oxides that pollute the environment. Ship Exhaust Gas Scrubber exhaust gas cleaning reduces sulphur (SO2) and particulate emissions from ship engines, generators, and boilers. Ship Exhaust Gas Scrubber should enable ships to meet sulphur emission limits as required by IMO MARPOL Annex VI regulations without switching to low-sulphur fuel. This report mainly covers the Ship Exhaust Gas Scrubber product type: Open Loop Scrubbers, Closed Loop Scrubbers, and Hybrid scrubbers.

The maritime industry has faced increasing scrutiny regarding its environmental impact. Heavy fuel oil, commonly used in ships, is high in sulfur content, which when burned, generates sulfur oxides that contribute to acid rain and respiratory issues in humans. The introduction of the IMO 2020 regulations, which limit the sulfur content of marine fuel to 0.5%, has prompted ship operators to either switch to low-sulfur fuel or invest in exhaust gas cleaning systems. Marine scrubbers present an efficient alternative to changing fuel types, allowing ships to continue using HFO while effectively reducing harmful emissions.

Marine scrubbers can be categorized into three main types: Open Loop Scrubbers, Closed Loop Scrubbers, and Hybrid Scrubbers.

1. Open Loop Scrubbers

Open loop scrubbers utilize seawater to wash the exhaust gases. The sulfur oxides are absorbed by the seawater, which is then discharged back into the ocean, often with a slight increase in pH. While this system is simple and cost-effective, it has faced criticism for its environmental impact, particularly in ecologically sensitive areas.

2. Closed Loop Scrubbers

Closed loop scrubbers, on the other hand, use a closed system where water is recirculated and treated to remove pollutants. The resultant brine is stored and disposed of properly, minimizing environmental impact. This type of scrubber is often preferred in areas where discharge into the sea is prohibited or regulated, making it more suitable for inland or sensitive marine environments.

3. Hybrid Scrubbers

Hybrid scrubbers combine the features of both open and closed loop systems, allowing operators to switch between modes depending on regulatory requirements and environmental conditions. This versatility has made hybrid scrubbers the largest segment in the marine scrubber market, as they offer flexibility and compliance with various regulations.

Wartsila, Yara Marine Technologies (Okapi), HHI Scrubbers, Alfa Laval, and Panasia are the top five manufacturers, accounting for approximately 52% of the global market share. Their strong presence is attributed to their innovative technologies, extensive experience, and strong customer relationships.

Applications of Marine Scrubbers

The marine scrubber market is primarily driven by two application segments: retrofitting existing vessels and equipping new ships.

Retrofit

Many shipping companies are opting to retrofit existing vessels with scrubbers rather than replacing engines or switching fuel types. This option is often more cost-effective and enables compliance with new regulations without significant alterations to operational procedures. Retrofit projects are gaining momentum, especially as the economic benefits of maintaining the use of HFO become evident.

New Ships

In addition to retrofitting, there is a growing trend towards equipping new ships with marine scrubbers from the outset. Shipbuilders are increasingly incorporating scrubber systems into the design of new vessels to meet future regulatory requirements and enhance sustainability profiles. This shift reflects a broader industry move towards greener technologies and operational practices.

Europe is currently the largest consumer of marine scrubbers, driven by stringent regulatory frameworks and a high concentration of shipping activity. The European Union has implemented strict emissions regulations, making scrubbers an essential part of compliance strategies for ship operators in the region. As awareness of environmental issues grows globally, other regions, particularly Asia-Pacific, are also beginning to adopt marine scrubbers more widely.

The marine scrubber market is expected to witness significant growth in the coming years, driven by several key trends:

Increased Regulatory Pressure: As global environmental regulations become more stringent, the demand for marine scrubbers is likely to rise. Compliance with IMO regulations will be a primary driver, encouraging more shipping companies to invest in EGCS.

Technological Advancements: Ongoing innovation in scrubber technology will enhance efficiency and effectiveness in removing pollutants. Manufacturers are investing in research and development to improve existing systems and develop new solutions that meet changing regulatory requirements.

Sustainability Initiatives: The maritime industry's focus on sustainability will continue to grow, pushing operators towards greener technologies. The adoption of scrubbers aligns with corporate social responsibility goals and public demand for cleaner shipping practices.

Economic Considerations: With the rising costs of low-sulfur fuel, many ship operators are finding it economically viable to install scrubbers as a long-term investment. The financial benefits of maintaining HFO usage, coupled with the reduction of compliance costs, will drive further adoption.

Hybrid Solutions: The trend towards hybrid scrubbers will continue as operators seek flexibility in complying with varying environmental regulations across different jurisdictions. Hybrid systems offer the advantage of switching modes based on operational needs and regulatory environments.
