"Actionable Insights to Fuel Your Growth"
Hybrid system for marine operations combines combustion engines with battery power for all types of vessels to save maintenance and engine life while increasing power and performance. As per the current scenario tugboats and support vessels are the major application of marine hybrid propulsion system. The shipping industry is responsible for most of the goods traded around the world. Many ships like cruise liners and tugboats travel in an environmentally sensitive area. To do so their engine needs to meet very strict emission regulation.
The global responsibility to the devastating effects of pollution and global warming has adopted tougher policies. Marine hybrid propulsion is the most developed technology used by leading giants in the shipping industry to meet the emission regulation laid down by the International Maritime Organization (IMO) regulates sulfur emission from a vessel. Marine hybrid propulsion systems offer a range of benefits like emission control and compatible with the marine environment, zero emission operation, high efficiency and flexibility of the propulsion system. Several countries across the globe are shifting towards the production of renewable energy. This has paved the way for the adoption of clean technology such as marine hybrid propulsion system in the existing traditional marine fleet.

The hybrid propulsion system is classified into three main categories viz. Diesel-Electric, Parallel Hybrid, and Serial Hybrid propulsion system mainly find its application in marine vessels to get optimal performance due to varying load. IMO has imposed a restriction on the emission of hydrocarbons, nitrogen oxides, sulfur content or particulate matter in sensitive marine zone. Hybrid propulsion offers a zero emission and makes it suitable to use in an environmentally sensitive zone. The major application of hybrid propulsion system are tugboats and all vessels along with yachts, cruise ships, ferries, and others.
The diesel engine is most widely used in the shipping industry and the fact is that it is more efficient when running to their maximum capacity. While the hybrid propulsion system offers flexibility and optimized performance which is key for the growth and adoption of the system. Many vessels do not operate at full power most of the time, and this is when it becomes necessary to shut down the main engine and generate power using a smaller generator. A more flexible system is to use battery storage system which results in zero emission. Emission regulations are getting stricter & marine environment is in danger due to huge pollution by the shipping industry. The system offers zero-emission which is a key factor in the growth and adoption of a marine hybrid propulsion system.
The growth of marine hybrid propulsion system is restrained due to its high development and implementation cost as compared tradition diesel system. It needs alternatives to store energy such as battery storage system which costs high. A high level of precautionary measures and care need to be taken while implementing marine hybrid propulsion system.
The leading giants in the marine hybrid propulsion system are Rolls Royce, Siemens, Volvo Penta, Cummins, Caterpillar, Fairbanks Morse, Danfoss, Nigata Power Systems, Kawasaki Heavy Industries, ABB, Man Diesel and Turbo, Masson Marine, Beta Marine, Steyr Motors, Schottel, and GE Power Conversion.
Segmentation of the Marine Hybrid Propulsion System
· Diesel-Electric Hybrid Propulsion System
· Parallel Hybrid Propulsion System
· Serial Hybrid Propulsion System
· Offshore Support Vessels (OSV)
· Cruise Ships
· Defence Vessel
· North America (USA and Canada)
· Europe (UK, Germany, France, Italy, Spain, Russia and Rest of Europe)
· Asia Pacific (China, India, Japan, Australia, Southeast Asia and Rest of Asia Pacific)
· Latin America (Brazil, Mexico and Rest of Latin America)
· Middle East & Africa (South Africa, GCC and Rest of Middle East & Africa)
The marine hybrid propulsion market has been segmented into North America, Europe, Asia Pacific, Latin America, and Middle East & Africa. The stringent emission regulations adopted by most countries in Europe leads to the potential of development for the marine hybrid propulsion system. The MEA and Asia Pacific operate the most number of offshore activities in the world. In this region, marine pollution is at an alarming level. Both the manufacturer and operator of the offshore activities have taken alternative ways to curb marine pollution. The North America region has the highest number of operating ships, cruises & yachts. Most of them are opting for marine hybrid propulsion due to high efficiency and flexibility of the system.
