With their worldwide distribution and abundance, gas hydrates have vast potential to become the next pillar of the energy industry. Although no entity has established methane extraction from hydrates at a commercial scale yet, extensive laboratory experiments have introduced several extraction strategies. Methods such as depressurization, thermal stimulation, and inhibitor injection are likely to disturb seabed integrity, which may result in catastrophic consequences. However, the CO<sub>2</sub> replacement method is inferred to be preserving the seabed stability, offering an opportunity to reduce anthropogenic CO<sub>2</sub> emissions safely. In this paper, we provide a comprehensive review of the progress of experimental work in developing methane-extraction methods for gas hydrate reservoirs. Depressurization combined with thermal stimulation can be proposed as a viable methane extraction method based on laboratory-scale experiments, however, a sustainable extraction method is yet to be developed to field-scale when both economic and environmental perspectives are considered. A handful of field production runs have delivered positive outcomes to establish the exploitability of natural hydrate reservoirs, but thorough investigations and scientific collaborations are needed to develop hydrate accumulations as a commercially viable energy source.</p></div>","PeriodicalId":100471,"journal":{"name":"Energy Reviews","volume":"2 1","pages":"Article 100013"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49748684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the development of polymerized small-molecule acceptors (PSMAs) has boosted the power conversion efficiencies (PCEs) of all-PSCs to over 18%. Polymerization sites on the terminal groups of small molecule acceptors play a decisive role in determining the absorption spectra, frontier molecular orbital energy levels, molecular packing and crystallinity, charge carrier mobilities and device performance of polymer acceptors. In this perspective, we focus on the latest advances of region-specific terminal groups and region-regular PSMAs, aiming to summarize the relationship between molecular structure–physicochemical properties–active layer morphology–device performance. Finally, the future design directions and challenges faced by region-specific terminal groups and region-regular PSMAs are discussed.

The circulating heat extraction process of working fluid will disturb the equilibrium state of physical and chemical fields inside the reservoir, and involve the mutual coupling of heat transfer, flow, stress, and chemical reaction. Revealing the coupling mechanism of flow and heat transfer inside the reservoir during geothermal exploitation can provide important theoretical support for the efficient exploitation of geothermal resources. This paper reviews the research advances of the multi-field coupling model in the reservoir during geothermal production over the past 40 years. The thrust of this paper is on objective analysis and evaluation of the importance of each coupling process and its influence on reservoir heat extraction performance. Finally, we discuss the existing challenges and perspectives to promote the future development of the geothermal reservoir multi-field coupling model.

Damaging and hazardous earthquakes in many countries (e.g., China, South Korea, and the United States) have motivated tremendous effort to understand the complexity of fault slip behaviors in response to fluid pressurization. This study reviews key characteristics of injection-induced fault slip and highlights prediction and mitigation strategies relevant to unconventional energy projects. This capability relies on adequate understanding and characterization of first- and second-order friction and stability behaviors of faults as well as impacts of fluid pressurization and its role in triggering aseismic, seismic, and transitional slip behaviors. Suitable methods of investigation and characterization are noted together with typical examples together with scientific advances in our understanding towards forewarning and mitigation. Present challenges are addressed relating to the understanding of complex second-order friction behaviors and the location and characterization of blind faults. These needs are aided in the integration of multi-scale and multi-physical data obtained from laboratory, numerical, and field studies to offer crucial information for induced hazard preparedness and rapid run-up assessment. Finally, emerging technologies contributing to an improved understanding, such as data analytics and machine learning, are discussed in heralding the next frontier for injection-induced seismicity research.</p></div>","PeriodicalId":100471,"journal":{"name":"Energy Reviews","volume":"1 2","pages":"Article 100007"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772970222000074/pdfft?md5=59d7573fa39c2515b4dab1bb4b5dff8e&pid=1-s2.0-S2772970222000074-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72072950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
