This is the 9th edition of the International Conference on Energy and Environment Research, ICEER 2022, took place in the middle of September, ISEP, Porto, Portugal (Hybrid). This book includes all the well-presented papers in ICEER 2022. The maturity of this conference series has now been reached, with a large number of participants from academia, as well as a few coming from the professional field. Linking together energy and environment research is not an easy task. However, it is now understood that these fields are interconnected and that the answer to the challenge of a sustainable future depends enormously on the willingness and capability of problem thinking in an integrated manner. This book presents the participants in ICEER 2022 contribution toward sustainability, through energy and environment research, thanks for all.

This book, the conference proceeding, contains invited articles and contributory papers from the 9th International Conference on Energy Engineering and Environmental Engineering, organized by Beijing Jiao Tong University in Sanya, China, on December 9–10, 2022. It includes contributions from researchers and practitioners working in the area of energy engineering, hydrogen, hydrogen carriers technology environmental engineering, climate change & global warming, and related fields. The articles cover the topics such as new energy production, storage, transmission, electrolysis, electrolyzes chemical, thermochemical, electrochemical hydrogen, energy environmental protection, and environmental sustainability. The content caters to research scholars, students, industry professionals, companies, government bodies, and policymakers, who work in the field of energy and environmental engineering.

This book presents selected papers from the 7th International Conference on Advances in Energy Research (ICAER 2019), providing a comprehensive coverage encompassing all fields and aspects of energy in terms of generation, storage, and distribution. Themes such as optimization of energy systems, energy efficiency, economics, management, and policy, and the interlinkages between energy and environment are included. The contents of this book will be of use to researchers and policy makers alike.

New information and strategies for managing the energy crisis from the perspective of growing economies are presented. Numerous case studies illustrate the particular challenges that developing countries, many of which are faced with insufficient resources, encounter. As a result, many unique strategies to the problems of energy management an conservation, environmental engineering, clean technologies, biological and chemical waste treatment and waste management have been developed.
