Geophysics and the Energy Transition involves four sections: What is the Energy Transition and why storage so important; selecting sites for storage; advanced monitoring technology; and moving forward to integrating Carbon Capture and Storage (CCS) within the Energy Transition. Geophysics will also play a role in finding and developing alternatives to fossil fuels such as natural hydrogen and geothermal using much of the knowledge gained from the CO2 storage industry. To provide the public and others with the confidence to move forward with a structured and cost-effective energy transition, this book provides the necessary evidence that we can store CO2 safely and effectively and use this as a significant component of the energy transition. We can also find and store new energy sources. Geophysics and the Energy Transition is written by experts in the field who have practiced the science and engineering associated with the subsurface for years. CCS is an integral component of the new energy transition but the application of Geophysics in the future will extend well beyond CCS if we are going to transition successfully to a carbon neutral environment. Science, engineering, and technology applications are important for site selection, characterization and monitoring to assure safe storage in the subsurface and energy sustainability in the future.
