About this Virtual Instructor Led Training (VILT) This 5 half-day Virtual Instructor Led Training (VILT) course covers carbon capture and geological storage of carbon dioxide. Burning fossil fuels for energy is a major source of carbon dioxide emissions to the atmosphere. Most anthropogenic (man-made) carbon dioxide is emitted by coal-fired or gas-fired power plants, and significant quantities of carbon dioxide are emitted through the production and separation of carbon dioxide-rich natural gas and industries such as cement, iron and steel. Carbon Capture Utilization and Storage, or CCUS, involves the long-term storage of captured carbon dioxide emissions in subsurface geologic formations. This VILT course covers all aspects of CCUS including transport, storage and monitoring, economics and community engagement. It explores in detail the challenges of the current technology of geological storage, monitoring and verification including examples from working projects around the world. Many of these technologies are commonly employed by the petroleum industry. Successful deployment of CCUS will also require economic incentives, appropriate regulation, clarity on liability issues and acceptance by the community. These aspects of CCUS, and the corresponding opportunities for appropriately skilled organisations and individuals also will be discussed. Course Content at a Glance Context for CCS/CCUS as An Emissions-reduction Measure Principles of Geological Storage Finding Geological Storage Sites Stationary Sources of Carbon Dioxide for Capture Carbon Dioxide Capture Technologies Compression and Transport of Carbon Dioxide Economics of CCS/CCUS Community, Safety, Legal & Regulatory Issues Risk Assessment Training Objectives Upon completion of this VILT course, participants will be able to: Identify the need for Carbon Capture and Storage (CCS) Outline the key steps in the Carbon Capture and Storage process Distinguish between reservoir rocks and sealing rocks Describe the importance of permeability and porosity to storing carbon dioxide Contrast the geological structures and trapping mechanisms for storing carbon dioxide Describe the changes in geologically stored carbon dioxide over time Outline the monitoring techniques employed to ensure the carbon dioxide is safely stored Appreciate the industrial applications of carbon dioxide capture Recognize the scale of industry required for transporting and storing carbon dioxide Describe economic considerations for CCS/CCUS Outline the economic and environmental opportunities and challenges with using carbon dioxide injection in a range of applications Explain the challenges of regulatory frameworks and public acceptance in a CCS/CCUS project Identify potential risks of a CCS/CCUS project Outline the risk assessment and management process Target Audience This VILT course is ideally suited for a technical audience - geoscientists, petroleum and chemical engineers - as well as for economists, regulators, legal staff and managers wishing to learn more about the details of both the technical, regulatory and socio-economic aspects of carbon capture and storage. Participants should have: Experience with oil and gas, coal or other energy projects Basic understanding of the energy industry Course Level Intermediate Trainer Your first expert course leader spent 18 years in the Petroleum Industry before joining academia, in both technical and managerial roles with Shell, Arco and Vico. He has received numerous awards, including Distinguished Service, Honorary member and Special Commendation awards from the American Association of Petroleum Geologist (AAPG) and was AAPG's International Vice-President and recently chairman of AAPG's House of Delegates (the Associations Parliamentary body). He is an SPE Distinguished Lecturer (DL) and has served as DL for several other professional organisations, including, AAPG, IPA and PESA. He is currently a Professor of Petroleum Geology and Engineering at the Australian School of Petroleum, University of Adelaide. He holds the South Australia State Chair in Carbon Capture & Storage (CCS) and is also presently Distinguished Scientist of the Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC), having served earlier as the Storage Program Manager and Chief Scientist. Your second expert course leader has a wide and deep knowledge of major capture technologies: solvent, membrane and adsorption based technologies and has developed pathways for retrofitting CO2 capture and storage (CCS) to fossil fuel-based power plants. He has been actively engaged in Post-combustion capture project management and demonstration projects in Victoria's Latrobe Valley on CO2 capture and hydrogen production, and on CO2 capture using membrane contactor technology. He has led various feasibility studies for the Asian Development Bank on CO2 Capture at Indian Oil Corporation's refineries, for JPOWER on hydrogen production from Victorian brown coal and for Kawasaki on incorporation of CCS in hydrogen production from fossil fuel. He has authored multiple peer reviewed journal articles, co-authored various confidential reports on CO2 capture, utilization and hydrogen production and utility, and has presented his work at various conferences, symposiums and seminars. He has a PhD in Chemical Engineering from Monash University Australia and a Master of Technology in Process Engineering from Indian Institute of Technology Delhi India.     POST TRAINING COACHING SUPPORT (OPTIONAL) To further optimise your learning experience from our courses, we also offer individualized 'One to One' coaching support for 2 hours post training.
