Some Perspectives for the Gasification Process in the Energy Transition World Scenario

Abstract

Energy demand has increased over the years due to population growth, industrial, and socio-economic developments, cornerstones of human civilization. Additionally, climate change alarms are placing the energy transition in the top concerns of intergovernmental organizations. Therefore, there are several reasons for concern regarding the need for a new paradigm in the world energy scenario. This perspective article focuses on the contribution that the gasification process may have in the global energy transition scenario. The perspectives for a full world energy transition are that it cannot be accomplished without a transportation fuel transition and an industry transition. Biomass gasification is a sustainable process that allows the production of a large range of commodities such as electricity and heat, biofuels, and chemicals. Meanwhile, some challenges such as tar, impurities, and soot must be overcome or at least limited to an acceptable minimum to promote the economic viability of the gasification plants before they can effectively contribute to the world energy transition. In this regard, further research should be made focused on improving the syngas quality and the economic viability of a biomass gasification plant. This can be achieved by several means including new reactor designs, advanced gasification processes (e.g., plasma gasification and supercritical water gasification), and intensifying the gasification process.
