Recent Advances in Multiphysical Couplings for Energy Geotechnics Applications

2025

Abstract

Energy Geotechnics has emerged as a crucial discipline that significantly advances sustainable energy practices, carbon neutrality, and climate change mitigation. This paper provides some experimental and theoretical developments, focusing on recent contributions by the authors, particularly in applications such as nuclear waste storage, energy geo-structures, and carbon capture and storage. It begins with a comparison between traditional geomechanical approaches and the requisite advanced multiphysical methodologies in Energy Geotechnics. The paper then discusses through examples the crucial role of Hydro-Mechanical (HM) couplings, along with Thermo-Hydro-Mechanical (THM) and Chemo-Hydro-Mechanical (CHM) processes. These processes are pivotal in enhancing energy efficiency, reducing emissions, and promoting sustainable urban development, underscoring the need for continued exploration and understanding of these complex interactions.

Climate change mitigation

Climate change mitigation is action to limit climate change by reducing emissions of greenhouse gases or removing those gases from the atmosphere. The recent rise in global average temperature is mostly due to emissions from burning fossil fuels such as coal, oil, and natural gas. Mitigation can reduce emissions by transitioning to sustainable energy sources, conserving energy, and increasing efficiency. It is possible to remove carbon dioxide () from the atmosphere by enlarging forests, restoring wetlands and using other natural and technical processes.

Carbon capture and storage

Carbon capture and storage (CCS) is a process in which a relatively pure stream of carbon dioxide (CO2) from industrial sources is separated, treated and transported to a long-term storage location. For example, the carbon dioxide stream that is to be captured can result from burning fossil fuels or biomass. Usually the CO2 is captured from large point sources, such as a chemical plant or biomass plant, and then stored in an underground geological formation. The aim is to reduce greenhouse gas emissions and thus mitigate climate change.

Greenhouse gas emissions

Greenhouse gas emissions (abbreviated as GHG emissions) from human activities strengthen the greenhouse effect, contributing to climate change. Carbon dioxide (), from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the US, although the United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies.
