What is a Marine Scrubber?

An exhaust gas cleaning system, a scrubber, removes particulate matter and dangerous compounds from ship exhaust gas streams, including nitrogen oxide (NOx) and sulfur oxide (SOx). Before the shipping industry implemented exhaust gas cleaning systems, all exhaust was released into the atmosphere, seriously endangering human health and the environment. Scrubbers, on the other hand, may remove up to 98% of the SOx emissions. China, Greece, India, Japan, Singapore, South Korea, Norway, and the United Kingdom are the top nations for maritime travel.

• In August 2024, twelve large gas carriers (VLGCs), four of which are dual fuel, will be purchased by Singapore-based BW LPG, the owner and operator of LPG boats, from Norwegian shipping company Avance Gas.

Market Scope

Market Dynamics

Driver

Growing maritime trade

The construction and development of critical commercial routes, such as the Suez Canal, Panama Canal, and Arctic shipping lanes, also influence the growth of marine trade. Because these routes are essential to international supply networks, more ships are operating in these areas due to the increased use of these routes. Aside from following the law, increasing pressure from stakeholders, the public, and environmental organizations has led many shipping businesses to switch to more environmentally friendly operations. In the interim, marine scrubbers are thought to help reduce emissions; longer-term options, such as alternative fuels (like LNG and hydrogen), are still being developed.

Restraint

High installation costs

Scrubber retrofitting is a costly and technically difficult process for already-built boats. The ship's construction frequently needs to be altered to install the scrubber system. This may entail rearranging the engine room, cutting and rewelding portions of the ship, and strengthening other locations. These adjustments must be made precisely to guarantee that the scrubber interfaces with the vessel's current systems without generating operational concerns. Because of this, ship owners must pay more for labor, engineering, and occasionally dry-docking the vessel, which drives up the installation's entire cost.

Opportunity

Growth of green shipping initiatives

Scrubber technology innovation is growing along with green shipping initiatives. The marine scrubber industry is seeing a rise in the development of more adaptable and efficient systems that can handle a range of ship sizes and kinds while maintaining compatibility with varied exhaust systems.
