Green technologies, one of which is fuel cells, are being rapidly adopted due to their potential to mitigate environmental degradation. These energy storage devices contribute to controlling the pollutants in the environment and allowing for fuel flexibility, durability, scalability, and quiet operations, especially of vehicles. Hence, the estimated size of the global fuel cell market, which was $1,799.9 million in 2021, will witness a humongous CAGR of 33.2% from 2021 to 2030, to reach $23,743.4 million by 2030.

As per reports, 17% of the global emissions are the responsibility of the transportation industry, which, additionally, consumes one-fourth of the world’s energy. Thus, the transportation sector contributes considerably in the expansion of the fuel cell market as this technology serves as an alternative to conventional ICEs and Li-ion batteries, in which the major part of fuel energy is emitted as heat. In order to reduce GHG emissions and improve the efficiency of energy conversion, there is a great need to invest in advanced propulsion technologies.

The highest revenue generator in the fuel cell market is polymer electrolyte membrane (PEM) variants, with a 60% share in 2021. Automobiles with PEM fuel cells have numerous advantages over fossil-fuel-driven automobiles, including a higher fuel efficiency, environment-friendliness, a comparable power density, and compatibility with renewable energy resources. PEM fuel cells are primarily being utilized in the transportation sector because of their suitability for cars and buses. A favorable power-to-weight ratio means that the weight of the vehicle can be limited by using lightweight fuel cells.

Apart from transportation, the usage of this technology for renewable energy generation is picking pace. South Korea has some of the largest fuel cell parks in the world. Similarly, fuel cell capacity in the U.S. rose by more than 750 MW in 2021. Small-scale systems are utilized by telecommunications entities, utilities, railroads, and governments and traffic departments in the U.S. for backup power. Furthermore, in Japan and Europe, small-scale fuel cell systems are widely used to produce electricity for homes and commercial spaces.

In order to curb carbon emissions and, in turn, reduce the greenhouse effect, the demand for fuel cells is surging for transportation and stationary power applications.
