Abstract
Adopting renewable energy sources to the detriment of non-renewable energy matrices is a change in progress worldwide. This movement is in concordance with the mutual necessity to reduce the emission of greenhouse gases and decelerate the impacts of global warming. Green hydrogen has been pointed out as a sustainable energy alternative since it is a product from renewable energy sources and its production process is carbon-free. This work proposes a comprehensive review of the main methods to produce green hydrogen derived from solar thermal energy. The presented review mentions thermodynamic cycles concepts and the more quoted models regarding sustainability according to the literature. The qualitative analysis foresees parameters like the working fluid, energetic efficiency, the project’s production level, and performance. Considering the information presented, the organic Rankine cycle (ORC) is the most suitable cycle to elaborate a viable large-scale project, owing to the possibility of functioning with lower temperatures in the heat source. Brayton and Rankine cycles are indicated for intermediate and higher temperatures. This detailed revision of the proposed productive methods powered by solar thermal energy expects to guide future projects to describe a more insightful and profound proposition for an ideal plant.
