Abstract:

<abstract> In this work, the use of solar thermal energy in the Nordic Countries, especially in Denmark, is studied. Renewable energies, such as solar, are an important ally in the fight against Climate Change, with more countries betting on them. In the past, it may have been believed that the Nordic Region does not have enough solar radiation for solar energy to be profitable, but changes in the climate and technology have proven this statement to be wrong. The case of Denmark is a clear example, which has become a leading country when it comes to solar thermal energy. A study of the current Danish solar thermal market is conducted in this project in order to understand how this country is making the most out of this energy source. Three different plants are studied (Silkeborg, Vollerup and Gr?sten) and compared to those of other Nordic Countries (Akershus from Norway and H?meenlinna from Finland). It was found that the main difference between them is the size of the Photovoltaic (PV) parks. Whilst Denmark specialised in large-scale plants with a two-phase building process, the other countries are only using small-scale installations. After a deeper understanding of the Danish energy market, it is concluded that there is a solar thermal energy policy that allows its exploitation. Furthermore, an increase in the level of solar radiation in Denmark over the last decade has led Danish experts to believe that solar energy in the Nordic Countries is going to be even more profitable in the following years. It is believed that Denmark will continue its current expansion into this market and also that the other Nordic countries will soon enough join. </abstract>

Abstract:

We have, an overview is presented of the potential future demands and possible supply of solar energy to Iraq. Solar energy, which is clean, unlimited, and environmentally friendly, is presented as a renewable energy resource. Many problems such as CO2 emissions, industry, human activities, and electricity distribution grids have attracted much attention because of the current state of crude oil production and its prices. Moreover, estimations of solar radiation levels and of the efficiencies of photovoltaics (PVs), concentrated solar power (CSP), and solar chimney towers, have all been investigated. Those systems that combine various sources of energy are called hybrids and they have received much attention in recent decades. The basic features of solar radiation in Iraq are outlined, and the selection of those sites with potential for development of solar plants is based on the local largest solar radiation. Moreover, longitudinal and latitudinal orientation, wind, solar intensity, dust, temperature, rain, humidity, and pollution factors are all considered in the calculation of PV/CSP efficiencies. We know there is an abundance of fossil fuels in Iraq, energy shortages began in 1991 because of the perturbation caused by the full ruin of the country. The obvious renewable energy resource available in Iraq is the solar energy, and its exploitation would provide a means to reduce CO2 emissions from the burning of fossil fuels and to achieve self-sufficiency of electric energy and export the rest to neighboring countries. Solar energy is becoming increasingly important because of the climatic change in the form of global warming.

Abstract:

The Iraqi government and people are not fully aware of the importance of renewable energy, so developing renewable energy technology in the region is primarily and a result of individual’s initiatives and non-governmental organizations instead of official policy. The fossil fuel is not limitless though in the next hundred years will be vanished, the only continuous resource is the solar energy as a solution to hinder the CO2 emission from various sources of fossil and biofuel. The solar energy requires an immediate attention due to the climatic change that affects the global warming. Iraq is a region rich in solar energy, where the sun’s brightness increases more than 3300 hours a year. The solar radiation falling in the desert areas of Iraq, which now accounts for more than 60% of the country’s area. 437072 km2 is equal to hundreds of thousands of times the total energy generated in this country. This is given Iraq a hand to stay as an energy supplier in the future as well as the present supplier of energy in the form of fossil fuel. Iraq consists of 18 provinces, three of which are in the northern province of the Kurdistan region and each province has the powers of semi-independent and special budget allocated by the central government where the provincial councils can invest part of this budget in the establishment of solar power stations, especially the provinces that suffer from lack of energy through the exploitation of other areas (deserts) to create such stations. the middle and south of Iraq have an averaged from16 to 10 MJ/m2/day for 5 months in the north, 6 months in the middle and southern region, respectively. But in western desert of Al-Anbar district almost have 8 month of sun shine duration while the lowest is over 4 MJ/m2/day. This energy is quite sufficient to drive all thermal photovoltaics (PV), Integrated Solar Combined Cycle (ISCC) plant and all houses hold facilities of heating, cooling and water distillation along the year.

Abstract:

Hot carriers are electrons or holes that are created in semiconductors upon the absorption of photons with energies greater than the fundamental bandgap. The excess energy of the hot carrier cools to the lattice temperature via carrier–phonon scattering and wasted as heat in [the] picoseconds timescale. The hot-carrier cooling represents a severe loss in the solar cells that have significantly limits their power conversion efficiencies. Hot carrier solar cells aim to mitigate this optical limitation by effective utilization of carriers at elevated energies. However, exploitation of hot carrier energy is extremely challenging as hot carriers rapidly lose their excess energy in phonon emission and therefore requires a substantial delay of carrier cooling in absorber material. In this paper a simple model was formulated to study the kinetic energies and hence the energy levels of the photo excited carriers in the quantum dots (QDs) whereas Schaller model was used to investigate the threshold energies of considered QDs. Results strongly indicate low threshold photon energies within the energy conservation limit for PbSe, PbTe, PbS, InAs, and InAs QDs. These materials seem to be good candidates for efficient carrier multiplication. It is found also that PbSe, PbTe, PbS, InAs, ZnS and InAs QDs exhibit promising potential for possible hot carrier absorber due to their widely spaced energy levels predicted to offer a large phononic gap between the optical and acoustic branches in the phonon dispersion. This in principle enhances phonon bottleneck effect that dramatically slows down hot carrier cooling leading to retention of hot carriers long enough to enable their exploitation. Two novel strategies were employed for the conversion of hot carriers into usable energies. The first approach involves the extraction of the energetic hot carriers while they are ‘hot’ to create higher photo voltage while the second approach uses the hot carrier to produce more carriers through impact ionization to create higher photo current. These mechanisms theoretically give rise to high overall conversion efficiencies of hot carrier energy well above Shockley and Queisser limit of conventional solar cells.

Abstract:

The present study aimed to investigate the exploitation of Concentrated Solar Power (CSP) for the in-situ production of anti-wear TiC-based surface layers onto steel substrates. For this purpose, “solar” experiments were carried out at the installations of Plataforma Solar de Almería (Spain). TiC powder was pre-deposited onto carbon steel substrates that have been subsequently exposed to concentrated solar irradiation for various dwell time values. The temperature field developed at the specimens’ surface during solar exposure was recorded in real-time by the aid of an optical pyrometer. Microscopic observations revealed the characteristic microstructure features of the hardfacing surface layers obtained and preliminary dry sliding tests performed in a pin-on-disc apparatus, allowed to estimate their machinability using conventional cutting tools.

Abstract: “Solar energy is clean, renewable, sustainable, and cost-effective, but it also requires time to develop by individual”. Due to the current situation of fossil fuels eradication and over-exploitation across the world. The energy demands of the world are to be fulfilled by renewable energy sources. Among this Solar energy has the maximum potential to be exploited to the maximum level to full fill the energy demands of the world. Renewable energies contribute to the environmental, social, and economic development of countries [1]. There are various of clean and renewable energy sources such as Solar, biomass, wind, hydrogen, fuel cell, nanocomposite, and supercapacitor. Each of the energy sources are suitable for specific geographical locations and can suits from region to region [6]. Since ages Sun has been praised as a vitalizer of life. The total Solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 122 PW·year = 3,850,000 exajoules (EJ) per year. Most of the world's population live in areas with insolation levels of 150–300 watts/m2, or 3.5–7.0 kWh/m2 per day [2 google- Solar Wikipedia]. Solar energy is the most secure and ubiquitous source of energy to meet the power needs after coal exploitation. In present time installation of photovoltaic (PV) Solar modules are growing extremely fast. As result of the increase, the volume of modules that reach the end of their life will grow at the same rate in the near future. Global installed PV capacity reached around 773 GW at the end of 2020 [3] and is expected to rise further to 2840 GW by 2030 and 4500 GW by 2050 [4, 5-Abstract ].

Abstract Coal mining will damage water resources, based on the analysis of mine water resources in the western region of China. Using mine water as the medium, a coal-water-wind (solar) energy comprehensive green energy exploitation system is established. Mine water is stored in underground spaces formed by mining, and mine water purification is achieved by fractured rock and goaf. Using multistage underground reservoirs, through pumping to store energy, the unstable solar and wind energy is converted into a stable output power. The possibility of using the mine water as a medium to use the clean energy, and the prospect of the utilization of mine water resources in the future, is discussed.

Abstract:

Pd-based membrane reactors are strongly recognized as an effective way to boost H2 yield and natural gas (NG) conversion at low temperatures, compared to conventional steam reforming plants for hydrogen production, thereby representing a potential solution to reduce the energy penalty of such a process, while keeping the lower CO2 emissions. On the other hand, the exploitation of solar energy coupled with a membrane steam reformer can further reduce the environmental impact of these systems. On this basis, the paper deals with the design activities and experimentation carried out at a pilot level in an integrated prototype where structured catalysts and Pd-based membranes are arranged together and thermally supported by solar-heated molten salts for steam reforming reaction

Abstract This article critiques industrial-scale solar energy development in Puerto Rico as a form of green capitalism that threatens the archipelago’s self-determination. Rather than uncritically embracing supposedly benign ‘green energy’ as necessary for advancing environmental, climate and energy justice, we argue that where, how and with whom this energy transformation takes place is crucial for calling attention to and challenging the continuance of inequitable and unjust power relations. To counter Puerto Rico’s ongoing exploitation as a ‘blank slate’ for development, we visually juxtapose the harms of industrial-scale solar ‘farms’ with distributed on-site, rooftop solar projects organized by grassroots group members in south-eastern Puerto Rico’s Jobos Bay region.

Abstract:

Serbia is a suitable place for solar energy exploitation with more than 2000 sunny hours per year over 80% of its territory. In the paper, the existing state is analyzed and the possibilities of solar energy use are examined by employing a combined approach. This relies on the following elements: an attached conservatory with remote heat storage for space heating in the period October-April; a canopy covered by flexible organic photovoltaic modules for electricity production in the period May- September, and a solar water heating system throughout the year. In addition to an analysis of energy performance of the proposed design solution, its economic aspect is also discussed, which suggests that investing in energy efficiency projects should be encouraged provided the state adopts an appropriate system of subsidies for the use of renewable energy sources.

Abstract:

Screw expanders are volumetric machines particularly suitable in energy conversion with steam–liquid mixtures and for the exploitation of low temperature heat sources. This study explored the main criteria to evaluate the thermodynamic advantages and exergetic assessment of an innovative solar electricity generation system: Screw expanders are utilized as power machines and parabolic trough collectors as a thermal source. Such a direct steam generation solar system, which is based on the Rankine cycle, offers benefits in comparison with usual power plants with dynamic expanders: The best exploitation of low temperature heat sources, satisfactory thermal efficiency with steam–liquid mixtures, lower evaporation pressures, and reduced size. Under real working conditions, screw expanders can work at part-load operating conditions; thus, the chief purpose of the present paper was to analyze the exergetic advantages of the planned solar power system when solar radiation and off-design working conditions fluctuate. Initially, the polytropic expansion phase with a specific numerical model is described to evaluate the energy losses that affect the thermodynamic performance of screw expanders when installed in the planned renewable energy power plant. Subsequently, to explore the exergy harnessing in the exhausted steam at off-design working conditions and then to appraise the maximum exergetic efficiency of the proposed screw expander-based solar thermal electricity plant, numerical optimization was performed in a broad range of evaporation and condensation temperatures.

Abstract:

There are many forms of alternative energy, such as: the biomass energy, geothermal energy, hydraulic energy, wind power and solar energy. Each form has its natural characteristics and its own exploitation conditions. Thus, the choice of the best resource does not only depend on the provided energy capacity but also on other criteria. In order to select the energy to develop, our survey recommends the multi-criteria method for the best selection.

Abstract:

In light of the global crises that the world suffers from, the renewable energy exploitation is a viable solution to remedy the various energy crises, knowing that renewable energy is a source of environmental credibility, as it does not cause any pollution or any emissions harmful to the environment. Among the most important renewable energy sources, solar energy is the most important type as it can be exploited thermally by adopting various solar collectors, especially solar concentrators. This paper has been devoted to illustrate the types of solar concentrators, namely point-focus concentrators (Heliostat Field Collectors and Parabolic Dish Collectors) and linear concentrators (Linear Fresnel Reflectors and Parabolic Trough Collectors), in an attempt to clarify its principle and its multiple uses domestically and industrially, especially in areas that are characterized by the abundance of its direct solar radiation. The solar concentrator is a solar thermal energy concentration system, because its use reduces the consumption of fossil fuels harmful to the environment and directly contributes to climate change. Solar thermal concentrators are an effective alternative to fossil generators for thermal energy, as they have many important uses such as the solar electricity production of solar electricity in power plants, industrial and domestic water heating, and have many other industrial uses.

Abstract:

Access to energy is among the key pillars to socioeconomic and improved life style. The East African Community (EAC) countries, also members of sub-Saharan Africa, are among countries with enough energy resources but still struggling with low electricity access, and the lower proportion of citizens with electricity access challenges such as expensive tariff, frequent blackouts, and unreliable service still persists. Diesel technology is among the easy and fast installation technologies for a location with an urgent need of electricity while solar is a clean technology with free fuel. Considering the diversity of electricity tariffs, cost of diesel fuel, and suitability to solar energy exploitation in EAC, this paper intends to provide a technoeconomic analysis for reliable, affordable, and sustainable energy system in the region. A daily load of 94.44 kWh recorded from averaging electricity bills of a luxury house in Kigali, Rwanda, is used as research object, and HOMER simulations are carried on considering the level of such daily load being supplied by either (a) diesel generator, (b) solar + diesel technology, (c) PV + battery storage, or (d) PV + battery storage + grid system in each member country of the EAC. The results show that (a) solar energy is a feasible and applicable technology for energy generation for the whole six EAC countries; (b) for South Sudan, if it is a standalone system, the diesel technology is less costly than solar technology; however, solar energy can still be recommended to be adopted as it has no gas emissions; (c) except South Sudan, PV + battery storage technology is found to be more affordable and cleaner than any technology including diesel; and (d) the option of connecting PV + battery storage to the grid is found more economical for locations where grid interaction is possible because their levelized electricity costs (LCOE) are lower than the real electricity tariffs currently in use within each of the six EAC countries. The solar energy system with battery storage (both off-grid and grid connected) proposed in this research can lead to an efficient increase of national energy resource exploitation in the EAC countries, resulting in reliable, affordable, and sustainable energy access to all the citizenry of the EAC.

Abstract:

The ship’s power system is one of the most important systems on board. It is designed for uninterrupted power supply to all ship consumers under different conditions of exploitation. When designing a ship, various optimizations are conducted to build the ship as economically and environmentally friendly as possible. The paper aims to analyze the possibility of applying renewable energy sources (RES), particularly solar and wind energy, on an existing vessel by conducting technical and economic analysis. Data for the solar hour’s number and wind distribution are gathered from the six locations in the Adriatic Sea over 32 years period. Firstly, it was investigated if data were position dependent or independent. Performing a Pearson correlation coefficient and an ANOVA analysis with F-test, it was concluded that the RES analysis is position-independent (p > 0.05, p = 0.826). Secondly, the energy system model created in Simulink was used for the analysis of the electrical network fundamental parameters. Finally, the object of the analysis is the total costs of procurement, installation, and maintenance of the system within a period of 25 years. Consequences are savings in the cost of exploitation and reduction of harmful gas emissions. The use of solar energy would result in savings of 111,556 l of diesel fuel, while the savings from wind energy would be 170,274 l of diesel fuel for 25 years.

Abstract:

This paper analyzes the potential of solar energy and the efficiency of a solar system for real measurements. During the analysis, one-year radiation measurements for the city of Pristina were used. Analyzes show a high potential for exploitation. What affects the increase of efficiency of such systems is the possibility of use throughout the year. For each respective month is shown the potential of thermal energy that can be achieved and efficiency. The paper highlights the role of solar energy in maximizing the penetration of renewable sources. The analysis shows that in August the coverage of the needs for hot sanitary water from the proposed solar system is 99% and minimally in January by 16%. Taking into account the seasonal changes that apply to the country, I consider that a possible combination of central heating systems with those of sanitary water - solar system would be an adequate solution.

Abstract:

Energy self-consumption is one of the strategies used for the optimization of renewable energy integration in electrical systems within a framework of sustainable energy policy development. Renewable energy self-consumption additionally contributes to the promotion of distributed generation. The aim of the present study is to develop a hybrid territorial planning model for the siting of areas suitable for the joint exploitation of wind and solar energy targeted principally at self-consumption. The methodology employed was based on the analytic hierarchy process (AHP) and geographical information systems (GIS), and the general area considered was the island of Gran Canaria (Spain). This island has an isolated electrical system. The case study involved locating areas close to populated settlements which are generally cut off from areas commonly marked out for large-scale wind and solar energy exploitation. The areas located with the model were differentiated according to the municipality they were in. The model that has been developed can be applied to any territory. The results obtained with the model can then be incorporated into territorial planning documents and/or national and regional and/or municipal files with the aim of optimizing the integration of renewable energy for self-consumption and advancing distributed electrical energy systems.

Abstract:

Solar energy is a renewable type, clean, and inexhaustible which is sufficiently available on the Algerian territory. The energy received daily on a horizontal surface of 1 m2 is in the order of 5 kWh over almost the whole Algerian territory; the duration of sunshine surpasses 2000 hours annually and can reach 3900 hours on the highlands and the Sahara. The importance of this work is based on exploiting solar energy to produce electricity. This study is based on the experimental exploitation of solar energy using solar tree’s prototype suggestion. This new model is focused to replace the leaf of a tree by the solar cell, starting by examining the solar field and physical phenomenon related with it; the description of cell photovoltaic comes after; and finally, the dimension of the solar system and the experimental studies are virtually released in the University of M’sila. In this work, a prototype of new artificial solar tree is proposed experimentally by using material available in the local market: 25 solar panels, metal support, electrical queues, regulator, and battery. The results highlight a power improvement in the case of the proposed new model (solar tree) compared to the traditional one provided (solar panel), for the specified time range between 8 am and 2:30 pm. On the other hand, the traditional model values improve if the time dimension is extended from 2:30 pm to 6:00 pm. This is due to the temperature of the region and the presence of interstellar spaces between the cells of the solar tree.

Abstract:

Adequate recognition of the offshore wind energy potential may help coastal states frame proper energy policies for replacing nuclear and fossil fuel energy. In this study, we examined the application potential of the offshore wind energy generated by 31 offshore wind farms designated by the Taiwanese government for future exploitation. Our findings indicate that offshore wind energy (through its substantial power generation volume and capacity factor) can play the most pivotal role in future power generation for Taiwan. A total of 59.3 TWh of electricity produced from offshore wind energy and solar photovoltaics (PVs) each year could replace the power generated from nuclear energy by 2025. Coal-fired power generation could be replaced by offshore wind energy and other renewables by 2032. The full exploitation of offshore wind farms as detailed in this study (103.4 TWh/year), together with other renewables, could reduce the share of liquefied natural gas-fired power generation to 5.6% of the total Taiwanese power supply by 2040. Realizing the ultimate target of 100% carbon-neutral power generation would rely mainly on a further decrease in electricity consumption per unit of gross domestic product and the expansion of offshore wind energy and geothermal energy.

Creating conditions for the development and functionality of sustainable markets solar system is of great importance for the economy and the preservation of the natural environment in Serbia. Popularization of photovoltaic production equipment will lead to a reduction in prices and greater use of these devices by the population. Area needed for photovoltaic installation, which is sufficient for a family of four from 7-15m² anywhere in the world. The average solar energy that reaches the Earth's 4kWh / m². The efficiency of photovoltaic technology is a low 10%, which means that it is possible to produce 0.4 kWh / m² per day. An average family spends about 6000 kWh per year, or 4 kWh per day per person. In this work we wanted to show the possibility of using solar energy. Also, the work presents technological capabilities of today's replacement of dirty technologies with it. Special emphasis is placed on good practice example of building a solar power plant. Confirmed the economic viability of solar power plant. In near future we even anticipate a full transition to solar energy technology, as the primary source of energy. Solar energy is clean, renewable, cheap, affordable and perfect in every respect as a source of energy for future technologies. The legislation favors the use of renewable solar energy .For its exploitation there are no legal obstacles like wind energy and hydropower. The energy that the sun emits during a year per 1 m2 of the roof in Serbia equals the energy obtained from burning 130 liters of oil, and when it is completely free. The greatest potential for using solar energy have cities in southern Serbia - Niš, Kuršumlija and Vranje.

Abstract:

Systems based on the coupling of heat pumps (HP) with solar hybrid photovoltaic and thermal technology (PVT) for domestic hot water (DHW) production are a valid alternative to conventional electric production systems. In previous research, simulation models were developed in order to study the dynamic behaviour of a plant set-up based on the integration of an air-to-water heat pump aimed at DHW production with a rated power of 700 W and a storage tank of 500 lt. It was coupled with a plant of 6 PVT flat uncovered hybrid solar collectors with a peak power of 300 W for each module. Starting from the results obtained in the pre-sizing stage, in this study, a plant configuration was analysed to maximize the exploitation of the low-temperature contribution provided by the adopted PVT collectors. With this aim, the efficacy of the introduction of a solar water preheating storage in addition to the one normally integrated into the HP was investigated. Different operational scenarios have been studied to evaluate the best energy management strategies to be implemented. They consider the influence that the thermal capacity of the solar storage could have on the system performance according to its volume and the setpoint temperatures. The obtained results show that the proposed plant solution generally allows an increase in solar energy exploitation for DHW production and a reduction in HP electricity consumption.
