CO2 Storage Site Selection: A Comprehensive Review of Current Approaches

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Global warming, driven by increasing anthropogenic greenhouse gas emissions, has emerged as a critical environmental concern. Carbon capture and storage (CCS) technology offers a promising solution for reducing CO2 emissions, but its effectiveness depends on identifying suitable candidates that can ensure safe, long‐term storage of CO2.

Effect of Injection Flow Rate on Product Gas Quality in Underground Coal Gasification (UCG) Based on Laboratory Scale Experiment: Development of Co-Axial UCG System [PDF]

, 2017
Underground coal gasification (UCG) is a technique to recover coal energy without mining by converting coal into a valuable gas. Model UCG experiments on a laboratory scale were carried out under a low flow rate (6~12 L/min) and a high flow rate (15~30 L/

IOT based Smart Helmet for Hazard Detection in mining industry [PDF]

arXiv, 2023
One of the most important parts of business, especially in the coal mining sector, is industrial safety. Suffocation, gas poisoning, object falls, roof collapses, and gas explosions are among the risks associated with underground mining. Therefore, air quality and the detection of hazardous events are crucial in the mining business.

Numerical Investigations of a Large Fire Exposure Crib Test—Presenting Different Pyrolysis Modelling Methodologies and Numerical Results

Fire and Materials, Volume 49, Issue 4, Page 371-387, June 2025.
ABSTRACT The need for numerical‐based approaches to investigate the fire behaviour in buildings with combustible components is growing due to the increasing use of timber by the construction industry to meet the ‘Climate Action Plan 2050’. This requires consideration of the complex kinetic processes that take place during the burning of the wood in the

An installation-level model of China's coal sector shows how its decarbonization and energy security plans will reduce overseas coal imports [PDF]

arXiv, 2021
China aims for net-zero carbon emissions by 2060, and an emissions peak before 2030. This will reduce its consumption of coal for power generation and steel making. Simultaneously, China aims for improved energy security, primarily with expanded domestic coal production and transport infrastructure.
