The rising concerns of climate change and global warming have made the current practices of industrial energy generation and consumption highly unsustainable. There is a growing awareness of the importance of renewable energy use in addressing climate change and establishing sustainable development. One of the renewable sources which have gained popularity over time is solar energy. Among the various solar technologies, one potential segment is solar thermal technology which involves solar thermal collectors. This technology mainly concentrates on providing industrial process heat across a wide range of temperature, and it's classified within the industry of Solar Heat for Industrial Process (SHIP). Though the SHIP technologies show strong technical feasibility, only few industries employ solar heat and there is a decreasing trend of adoption.  Hence, this research aims to understand the reasons for decreasing adoption by studying what and how are the factors affecting the adoption of solar thermal technology. This is done by performing a qualitative study across two industrial sectors food and chemical in the region of Middle East and North Africa (MENA). The obtained data by conducting semi-structured interviews are analysed using the Technological-Organization-Environment (TOE) theoretical framework.  The results from the study show that there are 9 important factors affecting the adoption of solar thermal technology that are categorized into technological factors (reliability, flexibility, financial attractiveness, and competitive alternatives), organizational factors (management support and resources) and environmental factors (regulatory environment, technology support provider and competitive pressure). Apart from the technological factors of lack of reliability and financial attractiveness, the organizational factors of lack of resources and the environmental factor of low incentives in MENA region, the aspect of cheap competitive alternatives especially in the MENA region, is causing the decrease in adoption within the food and chemical industry.

Energy is the core component for all industries. Most of the energy demand is met by fossil fuels, which is one of the main reasons for the high level of carbon emissions from industries. To decrease emissions or even become carbon neutral by 2050, many companies have made sustainability goals to implement renewablesin their production processes. Industries consume 74% of the energy in the form of heat, of which 30% of energy is consumed in low-temperature applications. Substituting fossil fuels in low-temperature applications with renewable energy sources such as solar-thermal technology (STT) can significantly reduce emissions. This study explores how can focus on sustainability by companies facilitate the diffusion of STT in low-temperature applications in brewery and mining industries. The study comprises a comprehensive literature review on sustainable development, drivers, and barriers of STT. The theoretical framework of the studyis based on diffusion of innovation by Rogers (2003). Empirical data is collected using semi-structured interviews to gain insights from multi-national companies about their focus on sustainability, transition towards renewable energy sources in meeting heat demand and aspects considered by companies. The study results show that companies focusing on sustainability goals are incorporating new renewable energy technologies such as STT in their processes. Companies are also making heat purchase agreements and are collaborating with neighbouring companies to incorporate STT. This form of integration of new solutions can increase the adoption rate of STT. Further, it is found that brewery companies have a better scope of implementing STT compared to mining companies.

Solar thermal technology is a rapidly evolving technology that still has a smaller market share than other green technologies. Therefore, this study aims to recognize barriers and drivers for the use of solar thermal technologies in the industrial sector. A literature review summarized the existing literature problems concerning drivers and barriers for the use of solar thermal technology in the industrial sector. To establish drivers and barriers to the use of solar thermal technology in the industrial sector and to supplement the literature review, a cross-sectional analysis was carried out in this study. Case studies have been performed in India, where two companies have undergone pilot testing of solar thermal systems in their manufacturing processes, and one has an option to incorporate solar thermal systems. Purposeful sampling was used to select the companies for the interviews, while convenience sampling and the snowball sampling were used to pick interview participants, further in this research six interviews was conducted from 4 different companies in the industrial sector. The findings were presented with thematic analysis. Drivers and Barriers have been divided into themes. Namely, Drivers include futuristic technology and Barriers include high costs, infrastructure requirements, more efficient and cheaper alternatives and lack of institutional support. Futuristic technology theme explains why this technology is beneficial for industrial adoption in the Indian market. High-cost theme explains why this technology is expensive over other renewable sources. Infrastructure requirements theme explains installation barriers influencing the adoption of solar thermal systems in the industrial process. Efficient and cheaper alternatives theme explains competitors influencing the adoption of solar thermal energy in the industrial sector. Lack of institutional support theme explains government and multinational companies that are influencing the adoption of solar thermal energy in the industrial sector. Aspects covered by the theme, high costs were most frequently mentioned among the respondents, suggesting that barriers play a significant role in implementing solar thermal systems. In contrast, aspects covered by the themes lack institutional support, infrastructure requirements, and more efficient and cheaper alternatives have not been addressed in the literature. Finally, the study concluded that the adoption of solar thermal energy in the Industrial Sector faces various barriers and drivers that must be investigated before the implementation.

The diploma thesis is focused on the dependence of heat storage on thermal conductivity, which is characterized by the thermal conductivity coefficient. Two basic materials were chosen for the measurements – universal plaster mixture and gypsum plaster. The thermal conductivity of the materials was increased by adding milled graphite powder, which conducts the heat very well. The taken samples were then examined for differences in the behaviour in the non-stationary thermal field and thermal-technical parameters – the specific heat capacity and the thermal conductivity coefficient – were determined.

This study aimed at evaluating and demonstrating the feasibility of using Concentrated Solar Thermal technology combined with biomass energy technology as a hybrid renewable energy system to supply the process heat requirements in small scale industries in Sri Lanka. Particularly, the focus was to apply the concept to the expanding hotel industry, for covering the thermal energy demand of a medium scale hotel. Solar modules utilize the rooftop area of the building to a valuable application. Linear Fresnel type of solar concentrator is selected considering the requirement of the application and the simplicity of fabrication and installation compared to other technologies. Subsequently, a wood-fired boiler is deployed as the steam generator as well as the balancing power source to recover the effects due to the seasonal variations in solar energy. Bioenergy, so far being the largest primary energy supply in the country, has a good potential for further growth in industrial applications like small hotels.  When a hotel with about 200-guests capacity and annual average occupancy of 65% is considered, the total annual CO2 saving is accounted as 207 tons compared with an entirely fossil fuel (diesel) fired boiler system. The annual operational cost saving is around $ 40,000 and the simple payback period is within 3-4 years. The proposed hybrid system can generate additional 26 employment opportunities in the proximity of the site location area.   This solar-biomass hybrid concept mitigates the weaknesses associated with these renewable technologies when employed separately. The system has been designed in such a way that the total heat demand of hot water and process steam supply is managed by renewable energy alone. It is thus a self-sustainable, non-conventional, renewable energy system. This concept can be stretched to other critical medium temperature applications like for example absorption refrigeration. The system is applicable to many other industries in the country where space requirement is available, solar irradiance is rich and a solid biomass supply is assured.

<p>Modeling microbial inactivation has a great influence on the optimization, control and design of food processes. In the area of food safety, modeling is a valuable tool for characterizing survival curves and for supporting food safety decisions. The modeling of microbial behavior is based on the premise that the response of the microbial population to the environment factors is reproducible. And that from the past, it is possible to predict how these microorganisms would respond in other similar environments. Thus, the use of mathematical models has become an attractive and relevant tool in the food industry.</p> <p>This research provides tools to relate the inactivation of microorganisms of public health importance with processing conditions used in nonisothermal and non-thermal food processing technologies. Current models employ simple approaches that do not capture the realistic behavior of microbial inactivation. This oversight brings a number of fundamental and practical issues, such as excessive or insufficient processing, which can result in quality problems (when foods are over-processed) or safety problems (when foods are under-processed). Given these issues, there is an urgent need to develop reliable models that accurately describe the inactivation of dangerous microbial cells under more realistic processing conditions and that take into account the variability on microbial population, for instance their resistance to lethal agents. To address this urgency, this dissertation focused on mathematical models, combined mathematical tools with microbiological science to develop models that, by resembling realistic and practical processing conditions, can provide a better estimation of the efficacy of food processes. The objective of the approach is to relate the processing conditions to microbial inactivation. The development of the modeling approach went through all the phases of a modeling cycle from planning, data collection, formulation of the model approach according to the data analysis, and validation of the model under different conditions than those that the approach was developed.</p> <p>A non-linear ordinary differential equation was used to describe the inactivation curves with the hypothesis that the momentary inactivation rate is not constant and depends on the instantaneous processing conditions. The inactivation rate was related to key process parameters to describe the inactivation kinetics under more realistic processing conditions. From the solution of the non-linear ordinary differential equation and the optimization algorithm, safety inferences in the microbial response can be retrieved, such as the critical lethal variable that increases microbial inactivation. For example, for nonisothermal processes such as microwave heating, time-temperature profiles were modeled and incorporated into the inactivation rate equation. The critical temperature required to increase the microbial inactivation was obtained from the optimization analysis. For non-thermal processes, such as cold plasma, the time-varying concentration of reactive gas species was incorporated into the inactivation rate equation. The approach allowed the estimation of the critical gas concentration above which microbial inactivation becomes effective. For Pulsed Electric Fields (PEF), the energy density is the integral parameter that groups the wide range of parameters of the PEF process, such as the electric field strength, the treatment time and the electrical conductivity of the sample. The literature has shown that all of these parameters impact microbial inactivation. It has been hyphothesized that the inactivation rate is a function of the energy density and that above a threshold value significant microbial inactivation begins. </p> <p>The differential equation was solved numerically using the Runge-Kutta method (<i>ode45</i> in MATLAB ®). The<i> lsqcurvefit</i> function in MATLAB ® estimated the kinetic parameters. The approach to model microbial inactivation, whether when samples were subjected to nonisothermal or to non-thermal food processes, was validated using data published in the literature and/or in other samples and treatment conditions. The modeling approaches developed by this dissertation are expected to assist the food industry in the development and validation process to achieve the level of microbial reduction required by regulatory agencies. In addition, it is expected to assist the food industry in managing food safety systems through support food safety decision-making, such as the designation of the minimal critical parameter that may increase microbial inactivation. Finally, this dissertation will contribute in depth to the field of food safety and engineering, with the ultimate outcome of having a broad and highly positive impact on human health by ensuring the consumption of safe food products.</p>
