First, we classify and review the main types of PV-T collectors, including air-based, liquid-based, dual air–water, heat-pipe, building integrated and concentrated PV-T collectors. This is followed by a presentation of performance enhancement opportunities and pathways for collector innovation. Here, we address state-of-the-art design modifications, next-generation PV cell technologies, selective coatings, spectral splitting and nanofluids. Beyond this, we address wider PV-T systems and their applications, comprising a thorough review of solar combined heat and power (S–CHP), solar cooling, solar combined cooling, heat and power (S–CCHP), solar desalination, solar drying and solar for hydrogen production systems. This includes a specific review of potential performance and cost improvements and opportunities at the solar-generation system level in thermal energy storage, control and demand-side management. Subsequently, a set of the most promising PV-T systems is assessed to analyse their carbon mitigation potential and how this technology might fit within pathways for global decarbonization. It is estimated that the REmap baseline emission curve can be reduced by more than 16% in 2030 if the uptake of solar PV-T technologies can be promoted. Finally, the review turns to a critical examination of key challenges for the adoption of PV-T technology and recommendations.</p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"97 ","pages":"Article 101072"},"PeriodicalIF":29.5,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1886070","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 main problem in recycling plastic waste is that its composition is highly heterogeneous while sorting and purifying solutions to obtain mono-streams are complex and require large investments, thereby hampering the economy of scale. Ideally, novel chemical recycling processes are designed to have mixed plastic wastes as input and higher value products are produced such as C<sub>2</sub>–C<sub>4</sub> olefins or aromatics instead of a low value oil. In this review we show the directions how we can realize these objectives. Classical thermal pyrolysis offers some possibilities but requires very high temperatures exceeding 800 °C to transform the plastic waste back into the desired temperatures. Nevertheless, because of its robustness, thermal pyrolysis of polyolefinic plastic waste is currently intensively studied and the first industrial applications are operated at low to medium temperature range to maximize oil as the main product. Catalytic pyrolysis is still under development, but under ideal lab-scale conditions around 85 wt.% of C<sub>2</sub>–C<sub>4</sub> olefins can be produced when pure polyolefin feeds are used. With improved catalyst design it should be possible to get this number further up without affecting the catalyst stability. As the yield of light olefins in pyrolysis is impacted by both the process design (reactor type, the efficiency of plastic sorting prior to conversion, flexibility towards feed composition) and experimental parameters (temperature, catalyst type, catalyst/feed ratio, contact mode, residence time, addition of inert or reactants) also further improvements are possible in this respect. To industrialize pyrolysis of plastic waste, short residence times (<1 s) are crucial to avoid secondary reactions and by-products such as methane, coke, and aromatics. Pyrolysis reactors that are designed according to these principles, such as downers, spouted fluidized bed, and vortex reactors, are envisaged to result in optimal yields of C<sub>2</sub>–C<sub>4</sub> olefins. However, coke formation seems to be inevitable and the reactor designs need to be sufficiently robust to allow for in-situ coke removal. For future research it will be crucial for the industrial viability of plastic waste pyrolysis to improve the purification of the plastic waste stream, optimize both the catalysts selectivity and stability, and design a suitable industrial reactor. It is envisaged that further innovations in these three areas will eventually allow reaching the 90 wt.% target.</p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"96 ","pages":"Article 101046"},"PeriodicalIF":29.5,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3268444","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}

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.

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.

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.

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}
