Large-scale underground storage of hydrogen gas is expected to play a key role in the
energy transition and in near future renewable energy systems. Despite this potential …

Underground storage of carbon dioxide (CO2) in geological formations plays a vital role in
carbon capture and storage (CCS) technology. It involves capturing CO2 emissions from …

Abstract The utilization of Underground Pumped Storage Power Systems (UPSP) addresses
the growing need for energy storage in the face of increasing intermittent energy sources …

This paper presents a high-level overview of site characterization, risk analysis and
monitoring priorities for underground energy-related product storage or sequestration …

A compressed air energy storage (CAES) facility provides value by supporting the reliability
of the energy grid through its ability to repeatedly store and dispatch energy on demand …

Geological structures in the subsurface have been used for the storage of energy and waste
products for over a century. Depleted oil and gas fields, saline aquifers or engineered …

Carbon capture and sequestration (CCS) is widely recognized as an important component
of technological approaches to directly address carbon dioxide (CO2) emissions. The …

Disposal of industrial wastewater and activities such as CO 2 CO_2 underground
sequestration depend upon pressure conditions within deep geologic reservoirs …

In the early construction of an underground gas storage facility in an oil and gas field in
southwest China, the increasing gas injection volume led to a continuous rise in energy …

In this paper, we develop a two-dimensional (2D) numerical model based on the finite
element method to analyse the impact of fracture networks on the behaviour of pressurised …
