In developing countries, industries and manufacturing sectors consume a major portion of the total consumption of energy, where most of the energy is used for low, medium or high temperature heat generation to be used for process applications known as process heat. The necessity to commercialize clean, cheap and efficient renewable sources of energy in industrial applications emerges from increasing concerns about greenhouse gas emissions. In developing countries, industries and manufacturing sectors consume a major portion of the total consumption of energy, where most of the energy is used for low, medium or high temperature heat generation to be used for process applications known as process heat. The necessity to commercialize clean, cheap and efficient renewable sources of energy in industrial applications emerges from increasing concerns about greenhouse gas emissions and global warming and decreasing fossil fuel use in commercial sectors. As an abundant source of energy, solar energy technologies have proven potential. Recent research shows currently only a few industries are employing solar energy in industrial processes to generate process heat while replacing fossil fuels. Solar thermal power generation is already very well-known and getting popular in recent years while other potential applications of the concentrated heat from solar radiation are little explored. This review paper presents a detailed overview of the current potential and future aspects of involving solar industrial process heating systems in industrial applications. In order to keep pace with this emerging and fast growing sector for renewable energy applications, it is necessary to get in depth knowledge about the overall potential of industrial processes in individual industrial sector where solar process heat is currently in use and identifying industrial processes are most compatible for solar system integration depending on temperature level and the type of solar collector in u. Solar industrial process heatSolar thermal processes for industrial applicationsRecent trends of energy production and consumption in manufacturing industries are notably unsustainable due to rapidly increasing greenhouse gas emissions. Developing countries throughout the world are trying to industrialize their own economy to create new opportunities for the young generation to address their own country as a developed one. For mitigating poverty through sustainable development, every developing country is following their own energy policy for employing environmentally friendly energy specifically in the industrial sectors,,,,.As a renewable and abundant source, solar energy systems are future sustainable solutions for industrial consumers although, some places have inadequate solar energy resource where solar industrial process heating may not be feasible, but many other places receive abundant solar radiation and implementing such systems will drive the industries towards sustainable zero carbon production future. Industrial processes are mainly dependent on either electricity or fossil fuels to supply industrial process heat. As the non-renewable energy sources are going to be finished in future and considering all the drawbacks like GHG emissions, demand for renewable energy sources is imminent. The major drawback which hinders the scope for small and medium scale industries to integrate renewable energy systems in their production pro. There are very few research papers which try to identify potential industrial sectors for integration of solar heat in industrial processes and none of them analyze the potential industrial sectors in respect of existing SHIP plants globally to determine the potentials for others which are feasible and already in practise. This review paper is the first one to do such an analysis in SHIP.Lauterbach et al. studied and reviewed the potential in the field of solar industrial process heat integrated with suitable industrial processes. The annual specific energy gain is determined using TRNSYS simulation depending on temperature level, location and solar collector type. In another work, Lauterbach et al. methodically analyzed an installed solar process heating system based on simulation and compared it with a validated model. Weiss et al. reviewed the solar industrial process heating potential among countries for medium temperature collectors and sought a solution for SHIP integration problem. Schnitzer et al. applied a newly developed investigation tool to investigate industrial energy systems and heat integration feasibilities through an Austrian dairy industry case study. IEA SHC task 33 and SolarPaces Task IV: Solar Heat for Industrial Processes identifies and discusses potential industrial sectors for SHIP integration,. Mekhilef et al. reviewed solar energy utilization by industrial applications thus identified potential industries [. In simple words, while we get the energy from heat conversion gained from solar irradiation, is termed as solar thermal energy. Like other renewable energy systems, solar thermal energy can replace the fossil fuels in industrial systems. The energy conversion systems employ a variety of solar thermal collectors along with concentrators which accumu.
