COVID-19 IMPACT

"Marine Ammonia Engines Industry Had a Negative Effect Due to supply chain disruption during COVID-19 Pandemic"

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The COVID-19 pandemic negatively impacted the Marine Ammonia Engines marketplace by disrupting global delivery chains and inflicting shortages of uncooked materials. Delays in the manufacturing and the transportation of the components of ammonia engines, labor crisis, and restrictive measures in shipping affected import/export access and thereby caused product lockdowns. Original equipment manufacturers of raw materials and auto engine components reported declining production processes cover the entire auto industry. This slowed down work on the application of ammonia-burning marine engines so as to also affect project schedules. Moreover, the unpredictable market demand due to the presence of COVID-19 disrupted the revenues of shipping services which in turn creates significant pressure on the manufacturers and other stakeholders involved in the marine ammonia engine market industry.

MARINE AMMONIA ENGINES MARKET SEGMENTATION

By Type

Based on Type, the global market can be categorized into Spark Ignition, Compression Ignition:

• Spark Ignition: The spark ignition (SI) ammonia engines function in a rather conventional manner insofar as typically an air-fuel mixture is ignited through the spark plug as with any common gasoline engine. Here, ammonia is injected and a combination with air in the combustion chamber and then fire is applied in order to start the combustion. Additional support such as hydrogen or pilot fuels may be needed in ammonia fired burners as ammonia is known to have a high ignition temperature but low flare one relative to other fuels. The spark ignition ammonia engine is considered more suitable to the smaller vessels or as a system mixed of ammonia with other fuels to boost up it’s capacity and durability. SI ammonia engines are important in applications where the fuel-air mixture needs to be well controlled and the engines offer a relatively cleaner and controlled burn environment.

• Compression Ignition: The compression ignition (CI) ammonia engines on the other hand enable a compressor to squeeze air to high pressure and temperature at which the ammonia fuel when injected ignites. This process is like the working of the diesel engines in that no spark is required from outside the engine. Nonetheless, ammonia’s low cetane number which determines the self-ignition characteristics of the fuel are some of the issues encountered in CI systems. Due to this reasons, CI ammonia engines typical utilize pilot fuels such as diesel or methanol to assist in ignition of the charge. These engines are normally employed in large vessels as the vessels usually demand for higher power and effectiveness. Current research developments of CI ammonia engines involve understanding how to optimise the factor that affects ammonia combustion and its complete inability to use pilot fuel so as to enable full-scale, carbon neutral maritime operations.

By Application

Based on application, the global market can be categorized into Ammonia Fueled Carrier, Ammonia Bunkering Vessel

• Ammonia Fueled Carrier: Ammonia-fueled carriers are ships intended to run on ammonia as their main energy supply. Since ammonia is a carbon-free fuel, the maritime industry can consider ammonia as the best solution to their strict emission requirements. Carriers relying on ammonia as a fuel source are well adapted to international large-scale shipping as decarbonisation is crucial but difficult due to the energy intensity of such vessels. These carriers are designed to combust ammonia in internal combustion engines or combined with fuel cells to realise near-zero emission levels. Some primary uses of ammonia fueled vessels are in dry bulk Own, container, and liquefied gas ships. The use of ammonia as a carrier is a recent development, but it has been proved efficient in reducing emissions through eliminating sulphur oxides and particle emissions, this means satisfying the quack demand from the international regulators and environmentally conscious clients.

• Ammonia Bunkering Vessel: Ammonia bunkering vessels are crucial to the market development of ammonia as a marine fuel. They involve in carrying and delivering ammonia fuel to the ships at sea or at anchorage similar to the concept of oil bunkering vessels. Because ammonia-fuelled engines will be increasing in number owing to rising demand for ammonia as marine fuel, the ammonia bunkering equipment is only possible with these vessels. They come equipped with specific containment facilities due to the dangerous nature of the product, which is liquid ammonia, and its handling needs considerable attention with reference to the pressure and temperature. Ammonia bunkering vessels are needed to create the larger environment for ammonia-fueled propulsion, it will enable ports and shipping lane access to the fueling ammonia-powered vessels. This infrastructure is prerequisite to the operational and commercial practicality of ammonia as a marine fuel.

MARKET DYNAMICS

Market dynamics include driving and restraining factors, opportunities and challenges stating the market conditions.

Driving Factors

"Environmental Regulations to Boost the Market"

A factor in the Marine Ammonia Engines market growth is the environmental regulations. The constraints to release greenhouse gases and the growing global demands to conform with international environmental standards are some of the most influential drivers for the Marine Ammonia Engines market. There are rules by agencies, for example, International Maritime Organization (IMO) that seeks to reduce the amount of carbon emissions and encourage resourceful options in marine fuel. Since ammonia does not emit any carbon during combustion, it has become one of the best options for ship operating companies that are being forced to reduce their emissions to the environment.
