Conceptual illustration depicting clean energy. The image shows the chemical symbol for hydrogen (H2) on a balloon in the clouds. When hydrogen is used as a fuel, whether in fuel cells or combustion engines, it primarily emits water vapour. This makes it a much cleaner fuel option when compared to fossil fuels such as coal, oil, and natural gas. These fuels emit carbon dioxide and other pollutants when burned. | |
