COVID-19 IMPACT

Decreased Demand Due to Travel Restriction and Lockdowns

The COVID-19 pandemic has been unprecedented and staggering, with the fuel gas supply systems market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. However, the market is now showing signs of recovery, and the projected high CAGR is attributed to the market's growth and demand returning to pre-pandemic levels.

The COVID-19 pandemic had a significant impact on the fuel gas supply systems market. The global shipping industry faced disruptions and reduced demand due to lockdowns, travel restrictions, and the overall economic slowdown. Shipbuilding activities and new vessel orders were put on hold or delayed, affecting the demand for the fuel supply systems.

However, as economies gradually reopen and international trade resumes, the market is witnessing a rebound. The increasing focus on sustainability and the transition towards cleaner energy sources are expected to drive the demand for advanced system for gas and fuel in the post-pandemic period.

LATEST TRENDS

Growing Demand for Green Hydrogen to Fuel Market Growth

The latest trend in the fuel gas supply systems (FGSS) market is the growing demand for green hydrogen as a sustainable energy source. Green hydrogen is produced by using renewable energy sources, such as wind or solar power, to electrolyze water and separate hydrogen from oxygen. This clean and versatile fuel has gained significant attention as a key solution for decarbonizing various sectors, including transportation and energy generation.

• According to the International Maritime Organization (IMO), by 2024, over 300 LNG-fueled vessels were in operation globally, leading to an increased demand for FGSS integration in marine propulsion systems.

• As per DNV’s Alternative Fuels Insight (AFI) platform, 58% of dual-fuel engine installations in newbuild ships during 2023 were supported by integrated FGSS, reflecting a major trend in green retrofitting and future vessel designs.

The increasing demand for green hydrogen is primarily driven by the urgent need to address climate change and reduce greenhouse gas emissions. As countries and industries aim to transition to a low-carbon economy, green hydrogen has emerged as a promising alternative to fossil fuels. It can be used as a clean fuel for transportation, energy storage, and power generation, offering a carbon-neutral or even carbon-negative solution.

The growing focus on green hydrogen has a direct impact on the market. FGSS play a crucial role in the storage, distribution, and utilization of hydrogen as a fuel. These systems ensure the safe and efficient supply of hydrogen to various applications, including fuel cell vehicles, industrial processes, and power plants. As the demand for green hydrogen increases, the need for robust and reliable FGSS also rises.

FUEL GAS SUPPLY SYSTEMS (FGSS) MARKET SEGMENTATION

By Type

According to type, the market can be segmented into low pressure and high pressure.

• Low Pressure FGSS: These systems typically operate at pressures below 16 bar and are commonly used in vessels where space and simplicity are prioritized. According to the Japan Ship Technology Research Association, low-pressure systems account for over 60% of installations in LNG-fueled vessels as of 2023.

• High Pressure FGSS: High-pressure systems, operating above 250 bar, are essential for vessels using high-pressure dual-fuel engines. As per DNV, nearly 40% of newbuild dual-fuel ships ordered in 2023 adopted high-pressure FGSS for performance efficiency and compact engine room layout.

By Application

Based on application, the market can be divided into cargo ship, cruise ship, and others.

• Cargo Ships: FGSS in cargo ships is gaining traction due to emission norms. According to the International Maritime Organization (IMO), over 180 LNG-powered cargo ships were in operation by late 2023, most equipped with customized FGSS solutions.

• Cruise Ships: Cruise lines are adopting FGSS for LNG propulsion to meet sustainability targets. As reported by Cruise Lines International Association (CLIA), 72% of new cruise ships on order in 2023 were LNG-ready, indicating heavy reliance on FGSS.
