“…Fuel cells exhibit high electrical efficiency of 60% (in power generation only mode) and thermal efficiency of up to 40% (in CHP applications) (Pöschl et al 2010 ), but can easily be integrated with other power generation systems like gas turbines or microgas turbines to further improve their performance. Also, biogas fueled integrated solid oxide fuel cell (SOFC)-CHP offers a modern energy system that can address both heat and power generation demands for decentralized grids with drastically higher electrical efficiencies (Wongchanapai et al 2013 ; Safari et al 2020 ; Safari et al 2020 ). Such high efficiency compared to other common combustion technologies is a result of not being limited by thermodynamic Carnot efficiency.…”

This review showcases a comprehensive analysis of studies that highlight the different conversion procedures attempted across the globe. The resources of biogas production along with treatment methods are presented. The effect of different governing parameters like feedstock types, pretreatment approaches, process development, and yield to enhance the biogas productivity is highlighted. Biogas applications, for example, in heating, electricity production, and transportation with their global share based on national and international statistics are emphasized. Reviewing the world research progress in the past 10 years shows an increase of ~ 90% in biogas industry (120 GW in 2019 compared to 65 GW in 2010). Europe (e.g., in 2017) contributed to over 70% of the world biogas generation representing 64 TWh. Finally, different regulations that manage the biogas market are presented. Management of biogas market includes the processes of exploration, production, treatment, and environmental impact assessment, till the marketing and safe disposal of wastes associated with biogas handling. A brief overview of some safety rules and proposed policy based on the world regulations is provided. The effect of these regulations and policies on marketing and promoting biogas is highlighted for different countries. The results from such studies show that Europe has the highest promotion rate, while nowadays in China and India the consumption rate is maximum as a result of applying up-to-date policies and procedures.

“…Fuel cell technology continues to occupy a place in the world of research, academic, industry, and community. Its functionality and contribution are huge as it involved in numerous applications from small to large scale such as stationary, transport, medical, tissue engineering, and more 1‐3 . Thirty years ago, hydrogen was described as “a central and indispensable item in a decarbonised, renewable energy system” for healthy, cost‐efficient, and non‐polluting energies 4 .…”

Summary Carbon quantum dots (CQD) and graphene quantum dots (GQDs) have been mentioned frequently. They have been selected in recent studies as they have unique and remarkable potential, especially in electrical, optical, and optoelectrical properties. CQD and GQDs have very high chemical and physical stability due to inherent inert carbon material, thus newly recognized as a kind of quantum dots material. Its environmentally friendly, non‐toxic, and naturally inactive nature is also a major attraction for scientists around the world. In this work, CQD and GQDs production methods are discussed in detail, including soft‐template method, hydrothermal method, microwave‐assisted hydrothermal (MAH) method, metal‐catalyzed method, liquid exfoliation method, electron beam lithography method, and others. Additive material has been introduced in CQD and GQDs to increase the ability and performance of CQD and GQDs such as nitrogen, sulfur, chlorine, fluorine, and potassium. In particular, the presence of additive material in CQD and GQDs shows an advantage in terms of energy level, which is very good at achieving specific requirements in properties such as optical, electrical, and optoelectrical. In addition, the existence of functional groups consisting of heteroatoms such as oxygen, nitrogen, sulfur, phosphorus, boron, and so on of zero‐dimensional carbon materials in providing an overabundance of the active electrochemical site for the reaction. The product of CQD and GQDs has various shapes and sizes influenced by several parameters such as synthesis temperature, growth time, source concentration, catalyst, and so on. The application of CQDs and GQDs composites in fuel cells has been clearly and scientifically stated as it has enhanced the performance of fuel cell technology.

“…Also, solid oxide fuel cell (SOFC) is one of the most promising technologies for power production in the future due to its high efficiency compared to rival technologies and its environmentally friendly energy production aspect 4 . For decades, one of the most popular ideas in energy systems integration in the literature was the idea of SOFC and gas turbine (GT) integration since this integration can provide higher efficiency 4‐6 . Several researches have studied biomass integration with SOFC‐GT systems, 5,7,8 and a variety of novel biomass gasification systems, integrated with SOFC systems, have been reviewed and discussed by literature 9‐13 .…”

A novel approach is presented to reduce the moisture content of biomass by employing a solar dryer. The impact of decreasing moisture contents on the key parameters of the system is investigated. Also, the effect of air mass flux on drying rate of biomass is evaluated and discussed considering three alternative air mass flux rates as well as two different time periods for drying and discharging biomass, namely 15 and 30 min. Results demonstrate that moisture reduction improves the output power and efficiency of the system from 265 kW and 30% up to 295 kW and 57.6%, respectively; in other words, employing solar dryer leads to an improvement of electrical efficiency up to 27.6%. The best efficiency performance of system is achieved by the 15 min drain time and air mass flux of 0.011 kgm−2s−1, while the best power generation of the system will be obtained by the 30 min drain time and air mass flux of 0.011 kgm−2s−1. Furthermore, the levelized cost of electricity analysis exhibits 0.39 $/kWh at the best performance of the system. The environmental analysis shows that the designed power plant has the potential to drop up to 721 tons of CO2/year, which has yielded an environmental benefit of 17,304 $/year when compared to a coal‐fired power plant of the same capacity.
