Solar thermal power plants for electricity production include, at least, two main systems: the solar field and the power block. Regarding this last one, the particular thermodynamic cycle layout and the working fluid employed, have a decisive influence in the plant performance. In turn, this selection depends on the solar technology employed. Currently, the steam Rankine cycle is the most widespread and commercially available option, usually coupled to a parabolic trough solar field. However, other configurations have been implemented in solar thermal plants worldwide. Most of them are based on other solar technologies also coupled to a steam Rankine cycle, although integrated solar combined cycles have a significant level of implementation. In the first place, power block configurations based on conventional thermodynamic cycles—Rankine, Brayton, and combined Brayton–Rankine—are described. The achievements and challenges of each proposal are highlighted, for example, the benefits involved in hybrid solar source/fossil fuel plants. In the second place, proposals of advanced power block configurations are analyzed, standing out: supercritical CO2 Brayton cycles, advanced organic Rankine cycles, and innovative integrated solar combined cycles. Each of these proposals shows some advantages compared to the conventional layouts in certain power or source temperature ranges and hence they could be considered attractive options in the medium term. At last, a brief review of proposals of solar thermal integration with other renewable heat sources is also included.

Direct formic acid fuel cells (DFAFCs) are potential candidates as power sources for various applications, especially in portable electronics and medical diagnostic devices. Though they have been the subject of considerable research, commercial prototypes of DFAFCs are rudimentary compared to other liquid fuel cells, particularly the widespread methanol‐based direct methanol fuel cells. Various strategies for rationally engineering the electrocatalysts for enhancing DFAFC performance have been explored in the last few years, such as alloying noble metals with earth‐abundant transition metals, designing specific morphological and structural arrangements, decorating the surface with corrosion‐tolerant cocatalysts, and providing better catalyst support for effective catalyst dispersion. An overall approach may be necessary and should include (i) understanding the underlying mechanism, which will guide the direction of catalyst engineering, (ii) employing morphological, compositional, and structural control of the electrocatalysts to improve catalyst utilization and enhance the intrinsic activity for real‐world applications, and (iii) integrating these in a proficiently designed cell architecture suitable for targeted applications. In this review, we focus on the recent advances in electrocatalysts, formic acid electrooxidation mechanisms, and DFAFC cell architectures, which could help address the opportunities and challenges of commercializing DFAFC as a prospective alternative power source for portable applications.

Drivetrain is one of the important subsystems in the wind turbine and faults and damages in the drivetrain significantly affect the wind turbine's downtime and nonavailability. Understanding the drivetrain dynamics and load effects that results in failures has been a major research area due to challenges in the drivetrain operations and maintenance. A systematic literature review of wind turbine drivetrains is presented according to key research areas of drivetrains, such as modeling and load effects on the drivetrain. Special emphasis is given for the floating wind turbine drivetrains. A review on the state‐of‐art modeling techniques of the drivetrain is presented. Studies concerning the aeroelastic load effects on the drivetrain components especially the gearbox and the bearings are discussed. Several key aspects such as aero‐hydro‐elastic interaction load effect and platform motion excitations on the floating wind turbine drivetrain dynamics are reviewed in detail. Finally, challenges related to floating wind turbine drivetrain are also discussed.

Advanced and sustainable energy storage technologies with tailorable electrochemically active materials platform are the present research dominancy toward an urgent global need for electrical vehicles and portable electronics. Moreover, intensive efforts are given to screen the widely available low‐cost materials with a focus to achieve superior electrochemical performance for the fabrication of energy storage devices. Transition metal‐based sulfides have prodigious technological credibility due to their compositional‐ and morphological‐based tunable electrochemical properties. Here the significant advances and present state‐of‐the‐art of such assured materials in different energy storage devices are discussed. Assessment of the intensive work invested in the progress of transition metals such as V, Mn, Fe, Co, Ni, Cu, Zn Mo, and W based sulfides along with their structural/compositional engineering and addressable aspects for electrochemical performance enhancement are highlighted. Additionally, discussions on critical strategies for decisive mechanistic and kinetic views for charge storage phenomena with key challenges, such as volume expansions, low stability, and sluggish kinetics, are discussed. Finally, the challenges and future prospects demands for strategic approaches of such materials with prominence in futuristic directions are concluded.

Notwithstanding the high levels of renewable energy resources across Sub‐Saharan Africa (SSA), modern energy use based on these abundant natural resources remains negligible. Furthermore, the current electrification rates and reliability of available power supply in the region have consistently remained significantly lower than the global average over the last three decades. And of the reasons advanced for this state of affairs, the lack of appropriate financing is said to be a crucial one. Therefore, focusing on a comparative overview of the dominant approaches to financing electrification, we characterize the persistence of this regional gap as a reflection of relative “policy stasis.” We then problematize this condition of stasis by employing the theoretical perspectives of mission‐oriented finance in conjunction with those of innovative finance and renewable energy innovation. In addition, we review relevant peer‐reviewed articles over the same period, and find evidence that indicates an underappreciation of financing models that stimulate endogenous technological innovation in renewable energy in SSA. Our analysis suggests that the types of innovation, associated configurations of financial actors, levels of capital intensity, and perceived risks in relation to beneficiaries, diverge from those accounted for in the dominant financing models. Consequently, we propose a novel, historically path‐dependent conceptual framework that emerges from the intersection among the concepts of mission‐oriented finance, endogenous innovation, and innovative financing, which we term “endogenous innovative financing.” This framework ultimately guides our recommendations for more promising financing mechanisms for resolving the interwoven challenges of sustainable universal electrification and renewable energy innovation in SSA.

Current collectors play a very crucial role in the performance of an energy storage device. Regarding supercapacitors, material design, processing, and current collectors' surface properties can result in substantial variation in energy density, power output, cyclic charge–discharge behavior, and other key performance parameters. Most of the reviews in supercapacitor materials and devices focus on the synthesis, characterization, and electrochemical properties of electrode materials. In the present report, the recent advances in supercapacitor electrodes in conjunction with current collector materials and design are summarized in light of various supercapacitor devices categorized concerning their applications and working mechanisms. It includes the literature documented on multifarious supercapacitors, that is, flow supercapacitors, alternating current line filtering supercapacitors, redox electrolyte‐enhanced supercapacitor, metal ion hybrid supercapacitors, microsupercapacitors, electrochromic supercapacitors, and self‐healing supercapacitors. To the best of authors' knowledge, this is a new and recent summarized report on the development of current collector materials based on intended applications and the working principles of supercapacitors.

Concentrated solar power (CSP) technologies have been developed over the past four decades for commercial operation, establishing them as reliable power generation sources in regions with high direct solar irradiance. The sizing of the solar field, thermal energy storage systems, and power block enables CSP plants to operate under various operating conditions, while also exhibiting capabilities to generate multiple products such as electricity, heat, desalination, and cooling. The limitations of CSP systems can be reduced by utilizing the positive traits of other technologies, thus resulting in hybrid plant configurations that can fully exploit different technology strengths while minimizing their individual weaknesses. This review presents the state of the art on CSP stand‐alone plants for both power generation and combined generation of different products. Subsequently, the characteristics of CSP plants hybridized with photovoltaics, wind, fossil fuels, and biomass systems are discussed for both power multiple‐product generation. The review of assessment methodologies provides suggestions for both assessment and performance analysis and comparison with other generation technologies. This review shows that hybrid CSP plants have clear advantages in terms of cost, flexibility of operation, adaptability, and capability for the multigeneration of different products compared with stand‐alone plants used to generate each product individually. Hybrid CSP plants have advantages and can be designed to satisfy multiple demands on a case‐by‐case basis and are valid alternatives to combinations of stand‐alone plants.

The Nordic power system will play an important role in a future carbon‐neutral European power market. In this study, 43 scenarios in 15 Nordic power market outlooks published between 2016 and 2019 are reviewed. Most scenarios see high future power prices with substantial correlation with assumed gas and emission quota prices. The underlying uncertainties in gas and emission quota prices are passed on to future power prices. The power prices are well above the cost of wind power, indicating that the wind deployment is either underestimated or might be largely dependent on non‐market factors. The models used for the outlooks have limited sector coverage and trade‐offs are made between computational resources and complexity. A set of recommendations for future outlook publications are proposed based on this review experience. Moving towards a low‐carbon future, more attention should be put to the demand side, especially with increasing importance of sector coupling and electrification. Also, to assess the profound uncertainties in the energy transition period, techniques besides scenario analysis can be applied. Explicit assessments on impacts of emerging topics, such as social oppositions to particular technologies and increased awareness of sustainability indicators besides clean energy, will add values for long‐term decision making in the power markets. Last but not the least, best efforts of clarity and transparency should always be ensured.
