Abstract

Over the past century, the increasing global demand for energy has intensified the search for alternative sources that can efficiently address humanity's needs while ensuring environmental sustainability and economic viability. This study investigates nuclear fusion as a potential candidate, detailing recent advances and discussing expected developments in the field. This literature review was primarily conducted using Google Scholar and specific keywords in order to filter articles based on their relevance to the project. Findings suggest that, despite remarkable progress in optimizing reactions and improving reactor models — for instance, Tokamaks and Stellarators — the production and handling of fusion fuel still face numerous scientific, technical, economic, and social obstacles, such as plasma control and stability, tritium manipulation, public acceptance, and profitability. Nonetheless, nuclear fusion has strong potential to provide an inexhaustible, clean, and powerful source of energy. This study highlights fusion as a means to achieve great technological advancements with the capacity to transform the global energy mix.
