Global warming has been altering climate change in the world. This research promotes environmental sustainability was fundamentally based on finding green combustion alternatives that help reduce the impact generated by the use of fossil fuels in the various sectors of the city of Lima, specifically in the engines of the automotive fleet.The experimental methodology that we applied in our research allowed us to reach results that show that it is possible to
use other energy sources such as green hydrogen for the combustion of the automotive fleet of the future and reduce carbon dioxide emissions in the capital city of Peru. That is, through the present study and the referential investigations for the investigation, it is concluded that green hydrogen has great energy potential to improve the quality of life and the environment.
