Abstract

The world society ratifies international measures to reach a flexible and low-carbon energy economy, attenuating climate change and its devastating environmental consequences. The main contribution of this Special Issue is related to thermochemical conversion technologies of solid fuels (e.g., biomass, refuse-derived fuel, and sewage sludge), in particular via combustion and gasification. Here, the recent activities on operational flexibility of co-combustion of biomass and lignite, carbon capture methods, solar-driven air-conditioning systems, integrated solar combined cycle power plants, and advanced gasification systems, such as the sorption-enhanced gasification and the chemical looping gasification, are shown.

Highlights

Human beings find themselves at the beginning of the 21st century in a contradictory situation in which, on the one hand, significant growth in global demand for energy is expected while, on the other hand, human activities have posed a dangerous rise in the global average temperature by approximately 1.0 ± 0.2 ◦ C above pre-industrial levels
Gasification and combustion of alternative fuels; Technological combinations of conversion processes based on renewable sources; Carbon capture and storage/utilization carbon capture and storage/utilization (CCS/U) technologies; Renewable energy for heating and cooling purposes to reduce peak demand, including energy storage systems to mitigate grid imbalances; Thermodynamic studies, computational fluid dynamics (CFD), and process simulation of the above-mentioned issues
The morphology and porosity of the hydrochar, characterized through Brunauer–Emmett–Teller, Barrett–Joyner–Halenda (BET–BJH), and scanning electron microscopy (SEM) analyses, were first evaluated and the sorbent capacity was compared with traditional sorbents

Summary

Introduction

Human beings find themselves at the beginning of the 21st century in a contradictory situation in which, on the one hand, significant growth in global demand for energy is expected while, on the other hand, human activities have posed a dangerous rise in the global average temperature by approximately 1.0 ± 0.2 ◦ C above pre-industrial levels. According to the above background and in support of the development of thermochemical conversion processes for solid fuels and renewable energies, this Special Issue contains nominated contributions to:
