Computational Models for Co2 Geo-sequestration & Compressed Air Energy Storage

"This book addresses two distinct, but related and highly important geoenvironmental applications: CO2 sequestration in underground formation, and Compressed Air Energy Storage (CAES). Sequestration of carbon dioxide in underground formations is considered an effective technique and a viable strategy for the mitigation of global warming and climate change. However, the short-term and long-term consequences of such an operation might be catastrophic if the involved hydro-chemo-physical and mechanical processes at the regional level are not properly addressed. Compressed air energy storage is a relatively new field of geoenvironmental application, but gaining a lot of momentum due to its effective utilization for energy storage. Renewable energy sources, such as wind energy, can be efficiently stored in the form of a compressed air in underground formations at off-peak times, and re-utilized upon demand. However, pumping and releasing compressed air can cause hydromechanical effects on the region, causing subsidence, upheaving and minor earthquakes. Considering the great potentials of these two geoenvironmental applications and their consequences, it is vital to model the involved flow processes and develop numerical tools, which are capable of describing such processes in an accurate, stable and computationally efficient manner. This book aims at attaining such models and numerical tools."--

Rafid Al-Khoury finished his PhD in computational mechanics at the Faculty of Civil Engineering and Geosciences at Delft University of Technology in 2002. Before that, he worked as a resident engineer, an experimentalist and a consultant engineer in various fields of civil engineering. Since 2004, he is working as a researcher in computational geoenvironment at the Computational Mechanics Chair at the Faculty of Civil Engineering and Geosciences in Delft University of Technology. His main area of interest is in geothermal energy, CO2 geo-sequestration, multiphase flow in porous medium domains and wave propagation in layered systems. He developed several analytical, semi-analytical and numerical models for these fields. The main focus of his research work is the formulation of innovative mathematical models and the development of efficient computational procedures capable of simulating multi-physical processes occurring in complicated geometry using minimal computational efforts. Along this line, Dr. Al-Khoury has published more than 25 peer-reviewed journal papers, and authored a book on “Computational Modeling of Shallow Geothermal Systems” in 2012, published by CRC Press/Balkema.

Jochen Bundschuh finished his PhD on numerical modeling of heat transport in aquifers in Tubingen in 1990. He is working in geothermics, subsurface and surface hydrology and integrated water resources management, and connected disciplines. From 1993 to 1999 he served as an expert for the German Agency of Technical Cooperation (GTZ) and as a long-term professor for the DAAD (German Academic Exchange Service) in Argentine. From 2001 to 2008 he worked within the framework of the German governmental cooperation (Integrated Expert Program of CIM; GTZ/BA) as adviser in mission to Costa Rica at the Instituto Costarricense de Electricidad (ICE). Here, he assisted the country in evaluation and development of its huge low-enthalpy geothermal resources for power generation. Since 2005, he is an affiliate professor of the Royal Institute of Technology, Stockholm, Sweden. In 2006, he was electedVice-President of the International Society of Groundwater for Sustainable Development ISGSD. From 2009–2011 he was visiting professor at the Department of Earth Sciences at the National Cheng Kung University, Tainan, Taiwan. By the end of 2011 he was appointed as professor in hydrogeology at the University of Southern Queensland, Toowoomba, Australia where he leads a working group of 26 researchers working on the wide field of water resources and low/middle enthalpy geothermal resources, water and wastewater treatment and sustainable and renewable energy resources (http://www.ncea.org.au/groundwater). In November 2012, Prof. Bundschuh was appointed as president of the newly established Australian Chapter of the International Medical Geology Association (IMGA).
Dr. Bundschuh is author of the books “Low-Enthalpy Geothermal Resources for Power Generation” (2008) (Balkema/Taylor&Francis/CRC Press) and “Introduction to the Numerical Modeling of Groundwater and Geothermal Systems: Fundamentals of Mass, Energy and Solute Transport in Poroelastic Rocks”. He is editor of the books “Geothermal Energy Resources for Developing Countries” (2002), “Natural Arsenic in Groundwater” (2005), and the two-volume monograph “Central America: Geology, Resources and Hazards” (2007), “Groundwater for Sustainable Development” (2008), “Natural Arsenic in Groundwater of Latin America (2008). Dr. Bundschuh is editor of the book series “Multiphysics Modeling”, “Arsenic in the Environment”, and “Sustainable Energy Developments” (all Balkema/CRC Press/Taylor & Francis).
