In the face of rising concerns over environmental sustainability, the shift towards renewable power sources in vehicle technology has intensified. This article explores the transition from internal combustion engines to cleaner alternatives like battery electric vehicles (BEVs) and hydrogen fuel cell vehicles (HFCVs). BEVs operate solely on rechargeable batteries, offering emissions-free driving and benefiting from advancements in battery technology. On the other hand, HFCVs utilize hydrogen to generate electricity through fuel cells, providing longer ranges, quick refueling times, and versatility in energy usage. Hydrogen fuel cells stand out due to their greater energy storage density, emission of only water vapor, longer driving ranges, quick refueling process comparable to petrol cars, and ability to store excess renewable energy. This technology extends beyond cars to buses, trucks, ships, and trains, contributing to reduced greenhouse gas emissions and air pollution. Moreover, hydrogen infrastructure scalability and lightweight fuel cell systems enhance overall vehicle efficiency. Notably, leading automotive companies such as Toyota, Hyundai, Honda, and Mercedes-Benz are actively involved in the development of hydrogen-powered electric vehicles. These companies are investing in polymer electrolyte membrane (PEM) fuel cell technology for their models, aiming to expand fuel cell lineups, reduce costs, and advance hydrogen infrastructure development. The future plans of these manufacturers include accelerating fuel cell system development, increasing production of fuel cell vehicles for commercial applications, and expanding the application of fuel cell systems across different vehicle segments. The pursuit of sustainable transportation through the integration of hydrogen and electric vehicle technologies signifies a positive step towards decarbonization and environmental conservation in the automotive industry.
