The article discusses how hydrogen fuel cells can power vehicles in a more eco-friendly way. It talks about how new vehicles with fuel cell systems have overcome challenges like size, safety, and reliability. The focus is on making fuel cell vehicles more mainstream for everyday use. These vehicles could be crucial in reducing emissions in the future, especially for long-distance heavy-duty vehicles. The study also looks at the entire process of producing, storing, and distributing hydrogen, which can be made using renewable energy sources. This "green" hydrogen can store a lot of energy efficiently. In the future, hydrogen-powered vehicles may be a strong competitor to electric vehicles, especially for long driving distances and heavy loads.
