Fossil fuels are the most significant energy source supplying global energy demand. They are projected to become depleted and significantly be a major greenhouse gas (GHG) emitter issue. Renewable and environmentally friendly fuel feedstock is increasingly pressing to save future survival. Hydrogen is one of the renewable fuel candidates because of its energy density and only produces water as a by-product. Steam methane reforming (SMR) is a major hydrogen production pathway that uses natural gas as feedstock. GHG are still emitted through SMR. Thermal conversion using pyrolysis is a relatively cost-effective and easy process that can be applied for wide feedstock variations such as biomass and synthetic waste. However, a large-scale pyrolysis reactor has several challenges due to the complex composition resulting in impurities in the pyrolysis products. The desired products from biomass and/or synthetic waste pyrolysis are oil and gas (such as hydrogen) that can be used as fuels and for chemical production. This article provides an overview of the factor that can be used to optimize hydrogen production. Yields and purity of hydrogen depend on feedstock composition, catalysts, and reactor operating parameters. © 2024 American Institute of Physics Inc.. All rights reserved.
