Hydrogen and fuel cells offer many benefits over conventional fossil fuels, such as coal, oil, and natural gas. Hydrogen and fuel cells are more efficient, as they can produce more energy per unit of mass than fossil fuels. Hydrogen and fuel cells are more environmentally friendly, as they do not emit any greenhouse gases or pollutants when used. Hydrogen and fuel cells are more secure, as they can be produced from domestic and renewable sources, reducing the dependence on foreign and finite resources. Hydrogen and fuel cells are more versatile, as they can be used for various applications and sectors, from transportation to power generation.
