Personal Bio:

Jiajie Wang is an Assistant Professor at Graduate School of Environmental Studies, Tohoku University, Japan. Her main research focuses on geo-resources and energy, and in recent years, she has been conducting research on such as CO2 capture, utilization, and storage (CCUS) technology, water-rock interactions, clean energy production, as well as other related topics within the field of geochemistry and environmental technology development. Efficient CCUS technologies have been obtained through elucidating and applying the mechanisms of carbon storage and hydrogen energy production during hydrothermal alteration of rocks. The results have been published in 23 academic papers in peer-reviewed journals such as Journal of CO2 utilization and International journal of Hydrogen Energy. Her research is funded by the Japan Society for the Promotion of Science, National Natural Science Foundation of China, etc.

Background and Goal


With the urgent need to create a carbon-neutral society, the development of clean energy production techniques to replace the fossil fuel, and CO2 capture, utilization, and storage (CCUS) techniques have attracted increasingly widespread attention. Although there have been many related mature approaches, one the main challenge for their application is the insufficient cost-efficiency. Here, we will introduce some advanced research and applications for the hydrogen energy production and CCUS, which applying geochemical mechanisms, and using nature resources (e.g., rocks, geothermal fluid) and waste resources, which are expected to be applied in large scale and will significantly contribute to the realizing of a carbon-neutral society.


How to efficiently generate clean energy in an environmentally friendly way, and how to storage huge CO2 in low-cost way are the main challenges for creating a sustainable carbon-neutral society. The applying of natural geochemical reactions and phenomenon, and use of natural resources and waste resources are potential promising solutions to these challenges. Here, we invited several young pioneer researchers who have obtained important achievements in the field of energy production and CO2 capture, utilization, and storage (CCUS) through geochemical approaches. Through sharing research progresses and ideas, we aim to provide multidisciplinary opinions and methodologies for energy production and CCUS, as well as to create a general future vision of a promising carbon-neutral society.

Scope and Information for participants

This workshop provides and forum for sharing advanced research and technologies especially on the development of clean energy production and CCUS technologies from multidisciplinary and diverse environmental geoscience aspects. The scope of the research topic includes but not limited in: environmental geochemistry, water-rock interactions, sustainability, mineral and energy resources exploration and recovery. The contributors are expected to address the main questions and challenges of using natural and/or industrial wastes resources for sustainable carbon-neutral society creation. New ideas and practical techniques are welcome, and the technique as well as economic feasibilities are expected to be elevated through discovering and addressing the potential challenges.
