At high temperatures, alkali elements will be released in gas phase as alkali atoms, alkali chlorides, alkali hydroxides and alkali sulphates. In biomass/coal-fired boilers, the release of these alkali species can cause problems such as corrosion, slagging and fouling, threatening the safe operation of the facilities. The information on the release dynamic is important for developing proper models for alkali metal transformation in solid fuel combustion and gasification. Therefore, accurate quantitative measurements of the release of different alkali species during thermal-chemical conversion processes of biomass/coal are important. In this paper, we review literatures published over the last few decades in the field of quantitative optical measurements of alkali metals performed in combustion/gasification processes, and the release modeling based on those optical measurements. Firstly, the current situation of biomass and coal utilization is discussed, including the speciation of alkali metals in biomass/coal and their adverse effects on facilities. Secondly, requirements for optical measurements as well as several quantitative optical techniques are introduced including the general principles, typical setups, calibration methods and major advantages and drawbacks. In contrast to off-line techniques, these optical techniques provide nonintrusive measurements with high temporal and spatial resolution, which are indispensable for alkali release modeling. Furthermore, the alkali release behaviors based on optical measurements in thermochemical conversion processes are discussed. Based on the experimental results, the kinetic data for alkali release were summarized. Alkali release modeling was fulfilled relying on the knowledge of alkali release mechanisms and the kinetic data. In addition, simulations of alkali metal release with computational fluid dynamics during the biomass/coal combustion processes are also discussed, providing valuable information for industrial processes. Finally, typical examples of industrial applications of optical measurement methods in solid fuel thermochemical conversion processes as well as waste incineration and other processes are presented.</p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"100 ","pages":"Article 101131"},"PeriodicalIF":29.5,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0360128523000618/pdfft?md5=f78171e98db5f0cd07a14df07f3b6762&pid=1-s2.0-S0360128523000618-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138468069","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}

A growing amount of research has been devoted to the combination of DAC with CO₂ conversion, leading to creative strategies which start to be scaled up. In this review, we have critically analysed the existing approaches by the degree of process integration. From the point of view of process intensification, the integration of both capture and reaction in the same vessel can potentially lead to equipment and energy cost savings besides other synergistic effects. In this vessel, the DAC and conversion can occur either in consecutive stages with change of feed or spontaneously in a cascade reaction without changing the conditions.

With manifold contributing factors such as the high demand for energy, highly over-populated areas, and fossil fuel depletion, the EU has proposed to cut greenhouse gas emissions by at least 55% of 1990 levels by 2030, on the ambitious road to becoming carbon neutral by 2050. Enlarging and diversifying efficient renewable resources is a crucial pillar to satisfying the overwhelming energy needs. The road to this goal is paved by the intensive implementation of solar resources, which are the most promising with their ability to cover an entire year’s energy consumption by just one hour of irradiation if almost 100% of the incoming solar energy could be converted. As widespread and evolved as solar photovoltaic (PV) systems might be, they do present a myriad of challenges in their lifetime. PV soiling is among the major bottlenecks in PV power plants due to its direct influence on both the performance and efficiency of the overall system. This work will shed light on soiling characteristics after guiding through the soiling concepts, rates, and geographical distribution probability. The nature of soiling, its composition, and its impact on the performance of PV modules with full-sized cells will be described. The essence of this review is based on the various cleaning mechanisms that aim to reduce soiling and enhance PV plant performance. This work is concluded by summarizing the review content whilst highlighting the current support and efforts put forth by worldwide organizations to embody the motivation and essence of requirements in the pursuit of soiling reduction and green energy pathways.","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":" 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135340944","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}

Since transport energy consumption primarily relies on fossil fuels, it has resulted in serious carbon emissions and environmental degradation. Moreover, the volatility prices of fossil fuel and unstable international security have attracted keen interest for many developing and industrialized countries looking for sustainable and clean alternatives. Liquid biofuels, including but not limited to bioethanol, biodiesel, bio-jet fuel, are considered as the most promising alternative and more expansive role in powering sustainable transport, for its carbon neutral and low-emissions properties.&amp;#xD; Liquid biofuels contribute 4% of transport in 2020 and have been foreseen to continuously grow. Liquid biofuels can be produced by diverse technologies and commercialized in various ways, easy-adapt to technical and policy challenges. Major challenges include technical bottleneck, initial and operational cost, byproduct treatment, and associated environmental concern.

Furthermore, this study analyzes the related policies, highlighting the challenges associated with the unstable supply of clean energy, raw materials, and quality control.
