Acceptance Model

<p>A solar thermal heating technology has a great potential in industries application. This paper presents a prediction of Malaysian industries acceptance on the solar thermal heating system for replacing the current heating technologies. In Malaysia, most of the heating technologies are using fossil fuel as a heating source due to the low price of the source. The solar thermal is another type of sustainable renewable energy. The objective of this research is to produce a Malaysian industries acceptance model in order to study the willingness of the Malaysian industries to migrate and use the new renewable energy technologies in their heating process. System dynamic simulation has been used to develop the novel solar thermal heating acceptance model by using the survey data collected from process industries in Malaysia. The focus of the research is in low and medium temperature categories of the solar thermal system since most of the process industries in Malaysia are involving with low and medium temperature in the heating process. The System Dynamic model was designed to predict the investment decision taken by the industries based on investment decision rules. The results with current support from the government show that the Malaysian industries acceptance towards solar thermal heating technologies is low. To enhance the willingness among the industries, a new policy on solar thermal energy application for industries properly need to be tailored. </p>

Abstract Solar thermal energy systems are future sustainable solutions for both domestic as well as industrial use. Solar thermal systems operating in medium temperature range (373-673 K) require concentrated solar-thermal heating (CSH). In this work, a comprehensive numerical tool is developed to design and study multipurpose on-sun CSH system. The model uses a combined Monte-Carlo ray tracing, finite difference method and all heat transfer modes. The model is validated with in-house experiment, which demonstrates its predictive capability. Next, the tool is used to optimise the cavity receiver geometry and predict the performance of the optimised CSH system under different direct normal irradiance (DNI) conditions. A CSH system using Therminol D12 as HTF is presented. Therminol D12 HTF based system is predicted to take longer time than the system using water as HTF, for heating water to a specified temperature because of the heat exchanger effectiveness. However, the designed CSH system using Therminol D12 can attain higher temperatures than water without pressurization and through the heat exchanger can be used as multipurpose system suitable for cooking, laundry, sterilization, process industry etc.

There is an increasing need for the integration of renewable energy into the energy sector in Egypt. As the electricity subsidies are residing for consumers in Egypt, electricity prices are increasing. This increase in energy prices can be mitigated by the integration of renewable energy technologies. One of the most promising renewable energy technologies that will help stabilize the energy situation in Egypt, is Solar Thermal Energy. Solar Thermal Energy has a great potential in Egypt due to the availability and intensity of direct irradiance in Egypt. Therefore, Egypt has an amazing opportunity as a developing country to start perusing solar thermal technologies; these technologies include decentralized and centralized technologies. Decentralized technologies are targeted more for regular consumers and centralized technologies are targeted more for power generation and industries.

There is a huge potential to deploy solar thermal energy in process heat applications in industrial sectors. Around 50 % of industrial heat demand is less than 250 °C which can be addressed through solar energy. The heat energy requirement of industries like automobile, auto ancillary, metal processing, food and beverages, textile, chemical, pharmaceuticals, paper and pulp, hospitality, and educational institutes etc. can be partially met with solar hybridization based solutions. The automobile industry is one of the large consumers of fossil fuel energy in the world. The automobile industry is major economic growth driver of India and has its 60 % fuel dependence on electricity and remaining on oil based products. With abundant area available on roof top, and need for medium temperature operation makes this sector most suitable for substitution of fossil fuel with renewable solar energy. Auto sector has requirement of heat in the temperature range of 80-140 oC or steam up to 2 bar pressure for various processes like component washing, degreasing, drying, boiler feed water preheating, LPG vaporization and cooling. This paper discusses use of solar energy through seamless integration with existing heat source for a few processes involved in automobile industries. Integration of the concentrated solar thermal technology (CST) with the existing heating system is discussed with a case study for commonly used processes in auto industry such as component washing, degreasing and phosphating. The present study is undertaken in a leading automobile plant in India. Component cleaning, degreasing and phosphating are important processes which are carried out in multiple water tanks of varying temperatures. Temperatures of tanks are maintained by electrical heaters which consumes substantial amount of electricity. Non-imaging solar collectors, also known as compound parabolic concentrators (CPC) are used for generation of hot water at required process temperature. The CPC are non-tracking collectors which concentrate diffuse and beam radiation to generate hot water at required temperature. The solar heat generation plant consists of CPC collectors, circulation pump and water storage tank with controls. The heat gained by solar collectors is transferred through the storage tank to the process. An electric heater is switched on automatically when the desired temperature cannot be reached during lower radiation level or during non-sunny hours/days. This solar heating system is designed with CPC collectors that generate process heating water as high as 90OC. It also seamlessly integrates with the existing system without compromising on its reliability, while reducing electricity consumption drastically. The system is commissioned in April, 2013 and since then it has saved ~ 1,75,000 units of electricity/year and in turn 164 MT of emission of CO2 annually.

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.
