“…We believe that in the solar energy sector, the global interest differences leading to trade conflicts have not been sufficiently investigated. The studies published so far focused primarily on issues of technology development [29][30][31][32][33], domestic policies in energy sector and their effects on the implementation of the sustainable development strategy [34][35][36][37][38][39][40][41][42][43]. Existing research on trade disputes in solar sector usually focus on a single case of conflict in bilateral relations only, for example between the EU and China [44,45] or the US and China [28,[46][47][48], while in this paper we attempt to analyze a broader range of trade disputes.…”

The development of the renewable energy industry is a priority of economic policies in many countries, since it is viewed as one of the key growth sectors in the economy, playing also a very important role in mitigating climate change. At the international level, renewable energy is an issue of international cooperation but also an area of high trade tensions between countries. The main goal of this paper is to examine the nature and sources of recent trade disputes in the solar photovoltaic sector, which is the most dynamically growing sector in the green energy industry. In particular, the paper explores the links between the contemporary trade disputes and modern protectionism and between protectionist policies and practices and the export competitiveness in the growing sector of the economy. To achieve the aim of the study we explore in detail the WTO trade disputes over photovoltaic (PV) products, which occurred in the years 2007–2018. The products covered by the analysis were solar modules and cells classified under the HS code 854140. In our research we also used measures of descriptive statistics, hierarchical cluster analysis and revealed comparative advantage indexes. Our key results demonstrate the existence of links between protectionist policy causing trade conflicts and the export competitiveness. The research has also allowed us to identify problems of future studies concerning the association between trade protectionism and global value chains in the solar energy sector.

As fuel consumption in the transport sector has increased at a faster pace than in other sectors, the use of electromobility represents the main strategy adopted by the automotive industry. In this context, as the number of electrical vehicles (EVs) will increase, it will also be necessary to increase the number of charging stations. The present paper presents a complete solution for charging stations that can be located in the office or mall parking area. This solution includes a mode 3 AC charging stations of International Electrotechnical Commission (IEC) 61851-1 Standard, an EV simulator for testing the good functionality of the charging stations (i.e., communications, residual-current device (RCD) protection) and a software application used for controlling the charging process by the programmable logic controller (PLC).

“…Concentrated solar power systems (CSP) represent very promising sources for the sustainable production of energy and, consequently in recent years, many efforts have been made by industrial companies and academic researchers to render this technology more and more profitable [1]. CSP systems convert solar power by using mirrors, or lenses, to reflect and concentrate a large amount of sunlight onto a receiver, which in turn collects and transfers the solar energy to a heat transfer fluid, which can be used to supply heat for end-user applications, to generate electricity by means of conventional steam turbines, and in many other applications [2,3]. The CSP receiver is a critical complex component and its thermal performances have been extensively studied in literature [4][5][6][7].…”

Experimental Investigation on the Mechanical Behavior of an Innovative Parabolic Trough Collector

et al. 2019

In the present work an experimental program aimed at assessing the mechanical behavior of an innovative parabolic solar trough is presented. More specifically, a lightweight and low-cost collector making large use of adhesive joints, which can be easily assembled on-site, still performing at a high efficiency, was designed. Static and fatigue tests were performed on a full-scale prototype of the collector in the pre-production stage. The tests included differential torsion, concentrated and distributed bending, and distributed load (wind effect). During the tests, a network of strain gauges was placed in the most critical locations to measure the strain field, while laser sensors and cable transducers were placed in strategic positions to measure the displacements. The results demonstrate the strengths of the innovative parabolic trough collector and support the assessment of its structural integrity.technologies, as reported for example in References [9,10]. According to References [11,12], the costs of the construction of the collector itself are mainly responsible for the still relatively high LCOE values.In this context, the main objective of the present work was to assess the structural integrity and the mechanical behavior of an innovative lightweight and low-cost parabolic collector. The target of cost reduction means that the parabolic collector is supposed to be easily assembled on-site, using a reduced amount of pre-assembled components (that otherwise have to be shipped in the assembly location). Pre-assembled components in a highly specialized industrial environment warrant the achievement of the delivered mechanical behavior. On the contrary, full on-site manufacturing poses some challenges for the achievement of the following desired performance: High levels of efficiency, in spite of its lightness, with a potential to reduce the LCOE. The design of this structure, initially devised at Massachusetts Institute of Technology (MIT) [13] and developed by Eni in collaboration with Politecnico di Milano and MIT, was driven by a general cost reduction approach in terms of materials, production, transportation, assembly, and maintenance. Consequently, the rigorous assessment of the structural integrity of this system plays a fundamental role. The main idea behind this new design concept is inherited from the aeronautical engineering field, in which structures must be very light, but, at the same time, must also guarantee excellent reliability. The most innovative aspects of the design are the large use of adhesive joints and the almost complete absence of welds, rivets, and bolts. This design approach is expected to significantly reduce the weight and the construction time, but, due to its high level of novelty, requires an accurate assessment of its structural reliability.Finally, it is worth mentioning that the present work shows a significantly innovative activity, since experimental tests of parabolic trough collectors in the literature are usually aimed at the assessment of the thermal efficiency of th...
