Fiseha Tesfaye - REWAS 2022: Energy Technologies and CO2 Management

The Minerals, Metals & Materials Series publications connect the global minerals, metals, and materials communities. They provide an opportunity to learn about the latest developments in the field and engage researchers, professionals, and students in discussions leading to further discovery. The series will cover a full range of topics from metals to photonics and from material properties and structures to potential applications.

Volume II of the REWAS 2022 proceedings contains peer-reviewed papers presented at the REWAS 2022: Energy Technologies and CO2 Management symposium, organized in conjunction with the TMS 2022 Annual Meeting & Exhibition and REWAS 2022. The symposium was sponsored by the TMS Extraction and Processing Division (EPD), Light Metals Division (LMD), and Energy Committee.

The papers in this volume intend to address issues related to intricacies, challenges, and development of new strategies as the reliance on fossil fuels for energy is unsustainable and has released an unprecedented amount of carbon dioxide into our atmosphere. The continual research and development effort into clean and sustainable energy technologies and efficient carbon dioxide management are of paramount importance to ensure the responsible progress of human civilization and innovations.

The REWAS 2022: Energy Technologies and CO2 Management symposium was open to participants from both industry and academia with a focus on energy-efficient technologies including innovative ore beneficiation, smelting technologies, recycling and waste heat recovery, as well as emerging novel energy technologies. The topics cover various technological aspects of sustainable energy ecosystems, processes that improve energy efficiency, reduce thermal emissions, and reduce carbon dioxide and other greenhouse emissions. Contributions from all areas of non-nuclear and non-traditional energy sources are discussed.

Topics include renewable energy resources to reduce the consumption of traditional fossil fuels; emerging technologies for renewable energy harvesting, conversion, and storage; new concepts or devices for energy generation, conversion, and distribution; waste heat recovery and other industrial energy efficient technologies; energy education and energy regulation; scale-up, stability, and life cycle analysis of energy technologies, and improvement of existing energy intensive processes; theory and simulation in energy harvesting, conversion, and storage; design, operation, and optimization of processes for energy generation (e.g., carbon capture) and conversion of energy carriers; energy efficiency improvement in process engineering (e.g., for biomass conversion and improved combustion) and electrical engineering (e.g., for power conversion and developing smart grids); thermoelectric/electrolysis/photoelectrolysis/fundamentals of PV; emission control; CO2 capture and conversion, carbon sequestration techniques, CO2 and other greenhouse gas reduction metallurgy in ferrous (iron and steel making and forming), non-ferrous and reactive metals including critical rare-earth metals; sustainability and life cycle assessment of energy systems; and thermodynamics and modelling for sustainable metallurgical processes.

We hope this volume will serve as a reference for materials scientists and engineers as well as metallurgists for exploring innovative energy technologies and novel energy materials processing.

We would like to acknowledge the contributions from the authors of the papers in this volume, the effort of the reviewers involved with the manuscript review process, and the help received from the TMS staff.
