Seawater desalination supplies 97 million m3 of freshwater daily to more than 300 people worldwide. The global market is dominated by two technologies, thermal and membrane desalination. These processes have adverse impacts on the environment in form harmful emissions into air water also human health. Therefore, our main research questions are: what extent can we minimize life cycle environmental impact conventional through integration concentered solar power collectors, how do various...

Abstract Using renewable energy to power seawater desalination technologies can reduce the environmental impacts of a process which is essential for global water security. However, uneven geospatial distribution resources and regions scarcity results in unequal benefits creates uncertainty policy making. Hence, this study explores relation between resources, freshwater demand, associated plants driven by at scale using comparative life-cycle assessment approach. We focus on an optimized...

In many parts of the world, desalination is only viable and economic solution to problem fresh water shortage. The current commercial technologies rely on fossil fuels are thus associated with high greenhouse gas emissions that a major cause climatic changes. Solar thermal-driven multi-effect distillation thermal vapor compression clean alternative conventional technologies. To comprehend this process, as well its features limitations, extensive modeling required. work, we proposed plant...

Qatar is an emerging renewable energy market in the MENA region and has made progress recent years. The natural gas-rich state abundant solar resources a national vision to generate 2% of its electricity from by 2020. A number green businesses are operating at different segments value chain. However, deployment residential commercial PV still remains very low. One reason for this lack incentives public adopt technologies because high capital cost per kWh price as compared utility power. This...

There is growing interest in enhancing the energy sustainability of seawater desalination processes given increasing reliance on this technology water-stressed regions. In paper, we present design and modelling an energy-efficient thermal plant (using low-pressure multi-effect distillation) powered by a solar linear Fresnel collector. A steady-state computer model was developed engineering equation solver (EES) using energy, mass, salt balance equations. The EES used to evaluate annual...

Purpose: This paper presents an overview of the power generation market in Sudan, solar energy potential, introduction to photovoltaics (PV) and dish Stirling engine (DSE), proposes a methodology for assessing feasibility these two technologies Sudan's climate. Methodology:We carried out detailed literature review electricity profile grid access, capacity, policy potential use Sudan generation.We also presented brief technology PV DSE.The principles economic analysis are discussed.Lastly, we...

Scientific research in the engineering and technology domains plays a centric role realizing sustainable development Africa. In particular, multidisciplinary (and sometimes even cross-disciplinary) approach is required when tackling Africas complex challenges such as poverty, climate change, energy access, water resources management, energy-water-food nexus, urban environment, cybersecurity, others. To advance this research, African researchers should be empowered to conduct high-quality...

Qatar is a country with huge potential for solar energy applications due to its reasonably high global horizontal radiation value. Further, can be used reduce the demand on fossil-fuel generated electricity hence creating more revenues from natural gas resources. Currently, residential sector consumes 57% of total consumption in Qatar. Moreover, has one highest per capita rates world; >15,000 kWh/year. Subsequently, at an individual level, carbon footprint high. It important that we find...

Conventional seawater desalination processes like the multi-stage flash (MSF) and multi-effect distillation (MED) are environmentally unsustainable. They consume large amounts of fossil fuels which a major cause climate change. Further, plants discharge highly concentrated brine can eutrophication damage marine life. Qatar, being country that faces freshwater scarcity, is dependent on for municipal water consumption. On average daily production capacity all in Qatar 1.5 million cubic meters...
