However, in response to various challenges, the Korean government has revised the existing strategy to incorporate other carbon-free energy sources, including nuclear power, to advance the energy transition. Nuclear power plants currently operate as baseload units owing to reliability and economic consideration, but flexible operation is becoming necessary to support the growing integration of renewable energy. This study examines the transition of Korea's nuclear power plants from baseload to flexible operation. Based on Korea's electricity supply and demand framework plans, this study assesses the effects of flexible nuclear operations on annual renewable energy output curtailment and fuel costs for 2030 and 2036 through power market simulations. Additionally, grid stability implications are evaluated using a power system simulator. The findings show that flexible nuclear plant operations can help mitigate output limitations and improve grid stability by providing flexibility and reserves. However, the provision of reserves from nuclear power plants incurs increased fuel costs due to the additional consumption of fossil fuels. While the flexibility of nuclear power contributes positively to carbon neutrality by increasing renewable capacity and improving grid reliability, increasing the flexibility of nuclear power plants may inadvertently increase the reliance on fossil fuel. This tendency, in turn, could increase overall fuel costs and carbon emissions, posing a challenge to achieving carbon neutrality.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"208 ","pages":"Article 115055"},"PeriodicalIF":16.3,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These residual fractions are readily available, and the evaluation of their potential use as raw materials in diverse conversion processes is an important contribution to the search for more sustainable bioenergy sources without jeopardizing food security. The present study aims to discuss the characteristics of the main solid residues of the cocoa production chain, cocoa pod husks (CPH), and cocoa bean shells (CBS); to review the conversion routes that have been applied in the improvement of these residues; and to carry out mass and energy balances to evaluate their potential in energy generation and biofuels production through processes such as direct combustion, torrefaction, gasification, fast and slow pyrolysis, and hydrothermal carbonization. The compiled data from the processes reviewed indicate that the residual biomass derived from the cocoa production chain can be considered a suitable raw material for use in thermochemical conversion processes and generate high-quality energy carriers, such as biochar, hydrochar, bio-oil, and syngas. This review identified the lack of experimental studies of these residues in some conversion processes, such as gasification or fast pyrolysis, thus indicating the pathway for further studies. The selection of appropriate conversion technologies and adoption of effective waste management strategies can minimize the environmental impact of these residues while producing valuable products. This approach could generate additional income streams within the cocoa value chain.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"208 ","pages":"Article 115048"},"PeriodicalIF":16.3,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four sharing strategies are investigated and implemented in a monthly post-delivery phase. In contrast, in decentralized architectures, each user operates its assets independently. In such frameworks, the costs/benefits are usually shared among users through market-based mechanisms that rely on users' bids. This work then explores the Pool market and Peer-to-peer transactions to investigate the impact of different bidding from the users' perspective. Ultimately, all the proposed centralized and decentralized approaches (10 in total) are assessed based on economic performances at both users' and community levels. Specific attention is paid to fairness within the community, which is challenging. Three indexes derived from economy and game theory are then considered, along with metrics tailored for energy communities. Results from a seven-user community indicate that the pool market systematically returns considerable savings among decentralized frameworks compared to peer-to-peer markets. More importantly, centralized frameworks systematically yield the most significant bill reduction (16 %) and fairer cost allocation compared to decentralized frameworks.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"208 ","pages":"Article 115054"},"PeriodicalIF":16.3,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While two-phase AD systems have successfully reduced sulfate in thermophilic fermentative systems, similar success under mesophilic conditions remains undocumented. This study evaluated different strategies to establish and maintain stable long-term sulfidogenic activity in high-rate fermentative reactors under mesophilic conditions. Three reactors were tested, each inoculated differently: R1 with mesophilic naturally-fermented vinasse, R2 with thermophilic naturally-fermented vinasse, and R3 with granular sludge. All reactors were operated at 30 °C with a 12-h hydraulic retention time. The addition of 0.25 gNaHCO₃ g⁻¹CODt during inoculation effectively maintained pH levels higher than 6.5, stimulating sulfidogenic activity in all systems, regardless of sulfate loading rate variations (3.9–4.8 kgSO₄ m⁻³ d⁻¹). R3 demonstrated superior buffering capacity and robust sulfidogenesis, achieving sulfate removal efficiencies of 63 ± 14 % in R1, 72 ± 15 % in R2, and 83 ± 16 % in R3, primarily driven by <em>Desulfovibrio</em>. Hydrogenotrophic methanogenesis persisted in all reactors, driven by <em>Methanofollis</em>, <em>Methanobacterium</em>, and <em>Methanosarcina</em> in R1, <em>Methanofollis</em> in R2, and <em>Methanoculleus</em> in R3. Despite methanogenesis occurrence, R3 exhibited higher acetate accumulation (&gt;3.5 gHAc L⁻¹), with great potential to boost acetoclastic methanogenesis in a two-stage AD scheme. The produced biogas was low in hydrogen (&lt;1 %) but rich in sulfide (up to 9 %), necessitating further gas treatment.

However, studies have focused only on unilateral governance. Given the inherent limitations and research gaps, how to empower firms’ green total factor productivity through multi-factors resonance has become an urgent issue. For this purpose, using the micro-data of Chinese listed enterprises from 2009 to 2018, a framework from digital and institutional governance for analyzing synergies was defined through the SBM, entropy weight TOPSIS, and system coupling models that measured green total factor productivity and co-evolution of data and environmental governance factors. Their causal linkages were further explored through the fixed-effects model, which not only applies “digital governance inclusion” as an emerging research touchpoint to theoretical research on green development, but also provides China’s micro-empirical references for global digitally-empowered environmental governance. The study found that: (1) The synergy between multi-factors stimulated green total factor productivity, but did not significantly drive a dramatic increase in its rise. (2) Influence mechanisms confirmed that endowments matching unlock human and innovation dividends, optimizing skill structure and expanding innovation boundary, thus promoting green efficiency. (3) The spillover paths indicated that the multi-endowments effect creates secondary diffusion upstream and downstream along the supply chain, which is not only constrained by a significant single threshold, but also exhibits industry heterogeneity.

The basic plausible pyrolysis mechanisms were first summarized based on the analytic pyrolysis of typical chemical components, i.e., cellulose, hemicellulose, lignin, protein, and lipid. As for the conventional pyrolysis proceeded by using Py-GC/MS, the influence of biomass types and operation parameters was discussed, which indicated that biomass types and final temperature played a dominant role in regulating the composition and distribution of products. Subsequently, the product release behaviors at different stages were revealed and discussed via Py-GC/MS experiments using stepwise pyrolysis. The primary objectives of different stepwise pyrolysis approaches (torrefaction and pyrolysis, two-step pyrolysis, and multi-step pyrolysis) were to produce value-added chemicals or increase bio-oil quality. Furthermore, the catalytic effects of various catalysts, including soluble inorganic salts, metal oxides, microporous zeolites, and mesoporous zeolite, were also summarized and compared to elucidate the role of catalysts in catalytic pyrolysis for targeted product production.

A novel hybrid approach combines bottom-up TEA and LCA tools to assess FTS catalysts, while top-down TLC methodology evaluates future projections of the CO₂ to jet fuel (CtJ) platform. The evaluation and comparison of the newly designed FTS catalyst (CYL) and a conventional catalyst (COC) on the CtJ platform are conducted within this scope.

Consequently, the CYL catalyst enables the production of jet fuel and diesel at a lower cost (−15 % to −17 %) compared to COC from 2027 to 2050. Furthermore, for both cases' equal net CO₂ capture, CYL requires 15 % lower CO₂ capture and thus 41 % lower CO₂ emissions from the CtJ platform than COC.
