The article discusses the ongoing advancements in decarbonization efforts, focusing on the progress made in carbon capture and storage (CCS) through various techniques like laboratory experiments, modeling studies, and field-scale testing. Furthermore, the integration of artificial-intelligence and machine-learning technologies into CCS is highlighted as a means to enhance data understanding and expedite decision-making processes. In addition to CCS, the article emphasizes the growing significance of hydrogen in meeting the rising energy demands globally. It notes that while the majority of global hydrogen production is currently derived from fossil fuels, there is an increasing exploration of alternative sources like electrolysis of water and geological/natural hydrogen. Moreover, the role of liquefied natural gas (LNG) in the energy supply chain and its impact on energy priorities, especially in addressing transportation needs, is underscored. The article also mentions the exploration of new energy sources such as geothermal and nuclear energy to diversify the energy mix and cater to the escalating energy demands. The article references several key papers and recommended readings that delve into specific aspects of decarbonization efforts, hydrogen production, and energy source exploration. It also profiles Guoxiang “Gavin” Liu, an engineer specializing in energy systems economics and subsurface expertise, who has contributed significantly to the field through his research and publications.
