Technological Prospection and Flowchart for Production of Biogas Enriched with Hydrogen: A Proposal for Renewable Energy Sources

Abstract

Over time, environmental issues have taken on significant proportions worldwide, making using renewable energy sources increasingly trivial, notorious, and indispensable. Projects focused on sustainability enable the expansion and diversification of current energy matrices, such as the potential use of biogas as an alternative source. Therefore, the project aimed to develop a flowchart proposal through technological prospection, given the production of biogas enriched with hydrogen through anaerobic digestion of solid waste. Thus, a technological prospecting of patents and quantitative analysis of scientific articles was carried out to show an overview of the production of biogas associated with hydrogen from 2012 to 2022, based on the studies that analyzed the viability and efficiency of the use of hydrogen for biogas production.
