Driver: Global focus on reducing carbon emissions and environmental impact
There has been a growing global emphasis on reducing greenhouse gas emissions and transitioning toward cleaner energy sources in recent years. Governments, organizations, industries, and individuals worldwide actively support initiatives to curb carbon emissions and mitigate environmental impacts. The marine sector is likely to be the fastest-growing market for fuel cell generators, owing to the increasing use of fuel cell systems in ships due to their high efficiency, reliability, and durability. The International Maritime Organization (IMO), a specialized agency of the United Nations, plays a pivotal role in regulating maritime activities to promote sustainability. In July 2021, IMO implemented mandatory measures to improve energy efficiency and reduce greenhouse gas emissions in international shipping. These measures encourage alternative low-carbon and zero-carbon fuels specifically tailored for marine applications.
Restraint: High upfront cost compared to conventional diesel or gas generators limits mass adoption
The high cost of catalysts in fuel cell generators serves as a significant restraint for the widespread adoption of this technology. Catalysts play a crucial role in facilitating electrochemical reactions within fuel cells, enabling the conversion of fuel into electricity. However, the cost of catalyst materials, such as platinum, is relatively high, which significantly contributes to the overall cost of the fuel cell system. This cost factor poses a challenge in making fuel cell generators economically viable, especially compared to other energy generation technologies, such as gas turbines, Stirling engines, and internal combustion engines (IC engines). Catalysts are vital components of fuel cells as they enhance their efficiency and power density by up to 46%.
Opportunity: Integration of renewable energy sources into power grids
Increasing renewable energy integration presents a significant opportunity for the fuel cell generator market. With the increasing share of renewable energy sources, such as solar and wind power, the need for effective energy storage and balancing solutions will likely increase. Fuel cell generators can play a crucial role in this integration process. They can efficiently convert excess renewable energy into hydrogen through the process of electrolysis, storing it for later use. This capability supports grid balancing as hydrogen can be used to supply power during peak demand periods or when renewable energy generation is low. Also, when there is a dip in renewable energy production, fuel cell generators can utilize the stored hydrogen to generate electricity, ensuring a stable and reliable power supply. This ability to store and dispatch renewable energy on demand makes fuel cell generators valuable for enhancing the reliability and resilience of renewable energy systems.
Challenge: Water management in proton-exchange membrane fuel cells
Water management is a critical aspect of proton-exchange membrane (PEM) fuel cells, which are commonly used in various applications, such as transportation, portable power, and distributed energy generation. Efficient water management plays a pivotal role in the optimal functioning and longevity of PEM fuel cells. The challenge lies in maintaining an appropriate balance of water within the cell to ensure efficient proton conduction, electrode reactions, and the prevention of membrane drying or flooding. Excessive water can flood the electrodes, hindering the reactant supply and causing performance degradation, while insufficient water can result in membrane dehydration and decreased proton conductivity. Therefore, effective water management strategies, such as using humidification techniques, careful design of gas flow channels, and implementing water transport materials, are crucial to maintaining the right water content within the PEM fuel cell.
