Ambitious timelines are set, involving important investment decisions to be taken in a 5-years horizon time. Here, we provide an in-depth review of alternative technologies for sustainable aviation revealed to date, which we classified into four main categories, namely i) biofuels, ii) electrofuels<span>, iii) electric (battery-based), and iv) hydrogen aviation. Nine biofuel and nine electrofuel pathways were reviewed, for which we supply the detailed process flow picturing all input, output, and co-products generated. The market uptake and use of these co-products was also investigated, along with the overall international regulations and targets for future aviation. As most of the inventoried pathways require hydrogen, we further reviewed six existing and emerging carbon-free hydrogen production technologies. Our review also details the five key battery technologies available (lithium-ion, advanced lithium-ion, solid-state battery, lithium-sulfur, lithium-air) for aviation. A semi-quantitative ranking covering environmental-, economic-, and technological performance indicators has been established to guide the selection of promising routes. The possible configuration schemes for electric </span></span>propulsion systems<span><span> are documented and classified as: i) battery-based, ii) fuel cell-based and iii) turboelectric configurations. Our review studied these four categories of sustainable aviation systems as modular technologies, yet these still have to be used in a hybridized fashion with conventional fossil-based kerosene. This is among others due to an aromatics content below the standardized requirements for biofuels and electrofuels, to a too low energy storage capacity in the case of batteries, or a sub-optimal </span>gas turbine engine<span> in the case of cryogenic hydrogen. Yet, we found that the latter was the only available option, based on the current and emerging technologies reviewed, for long-range aviation completely decoupled of fossil-based hydrocarbon fuels. The various challenges and opportunities associated with all these technologies are summarized in this study.</span></span></p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"96 ","pages":"Article 101073"},"PeriodicalIF":29.5,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2622300","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}

To tackle climate change issues, phasing out the usage of fossil fuels is seen as a priority, where the utilization of biofuel from microalgae serves as a potential sustainable energy source for various applications. These photosynthetic microalgae utilize solar energy and carbon dioxide to produce energy-rich compounds (i.e., starch and lipids), that can be further converted into biofuels of different types. Among different types of biofuels, biodiesel from the transesterification of triacylglycerols stands out as the most sustainable replacement of transportation fuel over fossil-based petroleum diesel. However, hurdles such as limited productivity, overall production cost and challenges in upscaling the algal technology leaves a huge gap on the road to commercialized microalgae-based biofuel. This review article first presents a comprehensive overview of imperative knowledge regarding microalgae in terms of algal classification, factors affecting the growth of microalgae during cultivation and different steps in upstream processing. This review also discusses recent advances in downstream processing of microalgal biorefinery. Additionally, this review paper focuses on deliberating various recent strategies of genetic modifications and their feasibility for enhanced lipid productivity in microalgae.

However, seemingly intrinsic degradation during cycling has made it less attractive throughout the years compared to graphitic carbon, silicon-blends, and more recently lithium metal itself. Nevertheless, with the recent unprecedented growth of the LIB industry, this review aims to revisit Al as an anode material, particularly in light of important advancements in understanding the electrochemical Li-Al system, as well as the growth of activity in solid-state batteries where cell designs may conveniently mitigate problems found in traditional liquid cells. Furthermore, this review culminates by highlighting several non-trivial points including: (1) prelithiatied Al anodes, with β-LiAl serving as an intercalation host, can be effectively immortal, depending on formation and cycling conditions; (2) the common knowledge of Al having a capacity of 993 mAh g−1 is inaccurate and attributed to kinetic limitations, thus silicon and lithium should not stand alone as the only ‘high-capacity’ candidates in the roadmap for future lithium-ion cells; (3) replacement of Cu current collectors with Al-based foil anodes may simplify LIB manufacturing and has important safety implications due to the galvanic stability of Al at high potentials vs. Li/Li+. Irrespective of the type of Li-ion device of interest, this review may be useful for those in the broader community to enhance their understanding of general alloy anode behavior, as the methodologies reported here can be extended to non-Al anodes and consequently, even to Na-ion and K-ion devices.","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"29 1","pages":""},"PeriodicalIF":29.5,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81603487","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}

Reaching decarbonisation targets is a long process, which will require radical changes and ‘out of the box’ thinking. In this context, islands have become laboratories for the green transition by providing spaces for exploring possibilities and alternatives. Here we explore how hydrogen (H2) energy technologies can be a critical ally for island production of renewable electricity in part by providing a storage solution. However, given the abundance of sunlight on many islands, we also note the huge potential for a more profound engagement between renewables and hydrogen technologies via the co-generation of ‘green hydrogen’ using solar fuels technology. Solar hydrogen is a clean energy carrier produced by the direct or indirect use of solar irradiation for water-splitting processes such as photovoltaic systems coupled with electrolysers and photoelectrochemical cells. While this technology is fast emerging, we question to what extent sufficient policy support exists for such initiatives and how they could be scaled up. We report on a case study of a pilot H2 plant in the Canary Islands, and we offer recommendations on early-stage policy implications for hydrogen and other solar fuels in an island setting. The paper draws on the literature on islands as policy laboratories and the multi-level perspective on energy transitions. We argue that particular attention needs to be given to discrete issues such as research and planning, and better synchronising between emerging local technology niches, the various regulatory regimes for energy, together with global trends.","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"28 1","pages":""},"PeriodicalIF":29.5,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90648878","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}

Fundamentally, this type of diffusion combustion can be represented by basic forms ranging from a small laminar candle flame, to a turbulent medium-scale sofa fire, and up a storage tank fire, or even a massive forest fire. Pool fire research thus not only has fundamental scientific significance for the study of classical diffusion combustion, but also plays an important role in practical fire safety engineering. Therefore, pool fire is recognized as one of the canonical configurations in both the combustion and fire science communities. Pool fire research involves a rich, multilateral, and bidirectional coupling of fluid mechanics with scalar transport, combustion, and heat transfer. Because of the unabated large-scale disasters that can occur and the numerous and complex 'unknowns' involved in pool fires, several new questions have been raised with accompanying solutions and old questions have been revisited, particularly in recent decades. Significant developments have occurred from a variety of different perspectives in terms of pool fire dynamics, and thus the scientific progress made must be summarized in a systematic manner. This paper provides a comprehensive review of the basic fundamentals of pool fires, including the scale effect, the wind effect, pressure and gravity effects, and multi-pool fire dynamics, with particular focus on recent advances in this century. As the fundamentals of pool fires, the theoretical progress made with regard to burning rates, air entrainment&lt;span&gt;&lt;span&gt;, flame pulsation, the morphological characteristics of flames, radiation, and the dimensional modelling are reviewed first, followed by new insights into the fluid mechanics involved, radiative heat transfer and &lt;/span&gt;combustion modeling. With regard to the scale effect, recent experimental and theoretical advances in internal thermal transport and fluid motions within the liquid-phase fuel, lip height effects, and heat transfer blockage are summarized systematically. Furthermore, new understandings of aspects including heat feedback and the burning rate, flame tilt, flame length and instability, flame sag and base drag, and soot and radiation behavior under wind, pressure and gravity effects are reviewed. The growing research into the onset and the merging dynamics of multiple pool fires in the last decade is described in the last section, this research will be helpful in the mitigation of threatening outdoor massive (group) fires. This review provides a state-of-the-art survey of the knowledge gained through decades of research into this topic, and concludes by discussing the challenges and prospects with regard to the complex coupling effects of heat transfer, with the fluid and combustion mechanics of pool fires in future work.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;&lt;","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"95 ","pages":"Article 101070"},"PeriodicalIF":29.5,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1752265","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}

The former is characterized as an early ignition of the fuel–air mixture, primarily initiated by an oil–fuel droplet or detached deposit. Meanwhile, super-knock is an occasional development from pre-ignition to high intensity knocking through detonation, which is either initiated by a shock wave interacting with a propagating reaction and cylinder surfaces or inside a hotspot with a suitable heat release and reactivity gradient. The phenomenon can be divided into four stages, including LSPI precursor initiation, establishment and propagation of a pre-ignited flame, autoignition of end-gases and development to a detonation. LSPI and super-knock are rare phenomena, difficult to observe optically in engines, and differences in methodologies and setups between steady-state experiments can lead to discrepancies in results. Experimental research has included more detailed approaches using glow plug-equipped engines, constant volume combustion chambers and rapid compression machines. In addition, the improved availability of mechanisms for fuel and lubricant surrogates has allowed researchers to model the oil–fuel interaction at the cylinder walls, evaporation and autoignition of oil–fuel droplets and regimes for different propagation modes of an autoignition reaction wave. This paper presents a comprehensive review of the underlying phenomena behind LSPI and its development to super-knock. Furthermore, it presents the methodology in experimental research and draws conclusions for mitigating strategies based on studies involving fuel, oil and engine parameters.

Nevertheless, one of the primary challenges of achieving a complete H₂ economy is the large-scale storage of H₂, which is unsafe on the surface because H₂ is highly compressible, volatile, and flammable. Hydrogen storage in geological formations could be a potential solution to this problem because of the abundance of such formations and their high storage capacities. Wettability plays a critical role in the displacement of formation water and determines the containment safety, storage capacity, and amount of trapped H₂ (or recovery factor). However, no comprehensive review article has been published explaining H₂ wettability in geological conditions. Therefore, this review focuses on the influence of various parameters, such as salinity, temperature, pressure, surface roughness, and formation type, on wettability and, consequently, H₂ storage. Significant gaps exist in the literature on understanding the effect of organic material on H₂ storage capacity. Thus, this review summarizes recent advances in rock/H₂/brine systems containing organic material in various geological reservoirs. The paper also presents influential parameters affecting H₂ storage capacity and containment safety, including liquid–gas interfacial tension, rock–fluid interfacial tension, and adsorption. The paper aims to provide the scientific community with an expert opinion to understand the challenges of H₂ storage and identify storage solutions. In addition, the essential differences between underground H₂ storage (UHS), natural gas storage, and carbon dioxide geological storage are discussed, and the direction of future research is presented. Therefore, this review promotes thorough knowledge of UHS, provides guidance on operating large-scale UHS projects, encourages climate engineers to focus more on UHS research, and provides an overview of advanced technology. This review also inspires researchers in the field of climate change to give more credit to UHS studies.</p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"95 ","pages":"Article 101066"},"PeriodicalIF":29.5,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1886077","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}
