Abstract
There has been an energy transition to renewable sources with a focus on zero carbon emissions due to climate change and the global need to reduce carbon dioxide emissions. Among these clean energy options, green hydrogen appears as a good energy vector because it has a high calorific value and does not pollute. Green hydrogen generation occurs via water electrolysis and the most developed commercial technology available for industrial application is alkaline, it has good durability and low specific costs. However, this technology features a low current density value and gas transmission through the membrane during dynamic operating conditions, which may result in a mixture of flammable gases and generate serious problems. One way to analyze the operation of these electrolyzers is through modeling and simulation, considering reviewed alkaline water electrolysis modeling from the perspective of thermodynamic, electrochemical, thermal, and gas purity. Several authors have proposed models on this topic, but due to its complexity, more studies are required. Therefore, this paper aims to provide a review of the works in the literature on modeling and simulating hydrogen via alkaline electrolysis, especially on the studies that modeled and validated through experimental work.
