Abstract:

Photocatalytic fuel cell (PFC) is primarily a synergistic integration of two emerging technologies, namely, photocatalysis (PC) and fuel cell (FC). Solar PC can decompose organic compounds while FC provides an electrical potential gradient to facilitate transport of electrons [1]. Therefore, PFC can be effectively applied to utilize solar energy for wastewater treatment and recovery of energy chemically stored in wastewater [2,3]. It is a promising technology for solving both environmental and energy problems. In order to conduct proper research for rapid development of PFC, we need to have good knowledge about the material properties and clearly understand the cell mechanisms of PFC. The Fermi level between the photoanode and the cathode forms interior bias that inhibits recombination of photogenerated electrons and holes, resulting in increase in visible-light activation of PFC [4]. Modification of photoelectrocatalysts and use of microfluidics are effective strategies for improving the PFC performance [5,6]. The PFC effects can also be manipulated by the system configuration, design and control for specific outputs and reaction rates. The speaker will present the fundamentals, latest development of PFC, and upcoming R&D challenges needed for enhancing the PFC technology.

Renewable Energy 2017 International Conference Keynote Speaker Wilfried G.J.H.M. van Sark photo
Biography:

Wilfried van Sark is associate professor at the Copernicus Institute of Utrecht University. He has over 30 years experience in the field of photovoltaics, ranging from thin film silicon and III-V solar cell experimental and modeling development and testing to solar cell processing development, out- and indoor performance of solar cells, policy and cost development. His current activities focus on employing spectrum conversion (down/up conversion) using nanocrystals to increase solar cell conversion efficiency for next-generation photovoltaic energy converters as well as performance analysis of (BI)PV systems in the field, in particular linked to the development of smart grid systems in the built environment.

Abstract:

Statement of the Problem: The transition to low carbon energy and transport systems requires not only the large-scale adoption of clean technologies and efficiency measures, but also new energy management strategies to efficiently incorporate these innovations. Grid integration of supply side technologies such as photovoltaics (PV) and demand side ones such as electric vehicles (EV) requires proper strategies for energy management. Smart solar charging using vehicle to grid (V2G) technology is a key element in matching supply and demand on a local level. Optimization of self-consumption and self-sufficiency would lead to lower stress levels on the local distributions grid. Methodology & Theoretical Orientation: The smart solar charging concept has been pioneered in Utrecht, and now will be extended in other pilot areas with different demographic characteristics. Analysis of PV generation and EV charging behavior will be combined with algorithm development, in order to optimize self-consumption and self-sufficiency. Findings: Increased self-consumption of PV can be reached only if car use agendas are known in combination with perfect solar forecasting.  Conclusion & Significance: Smart solar charging has benefits in many ways: more EVs powered with clean energy, better local air quality, increased social cohesion due to the sharing aspect, lower amount of cars in the streets. Investment in local grid extension can be postponed, leading to economical benefits for distribution system operators and consumers.

Abstract:

The decisions made during product development (PD) lock in 70–80% of the total product cost, and the quality of the product is also largely fixed. Therefore, decisions which are taken during the PD process have a great influence on product life cycle cost, quality and sustainability. The most important point of the PD process where trade-offs are made is in the concept phase when defining design specifications based on customer requirements. Developing a model to support trade-offs for sustainable PD is a significant concern for designers. This research attempts to consider these features simultaneously to make trade-offs between environmental issues and other customer requirements to select the best design specifications on their basis. In this research, sustainability is considered as a customer requirement, which then is translated into design specifications. Sustainable design is treated as an optimization problem to maximize value-added activities while minimizing environmental effects. A scoring model is defined to model sustainability, quality and cost in the PD process in order to find the optimum level of their combination therefore.

Biography:

Eyad. H. R. Fadda is with Department of Geography, Faculty of Arts and Social Sciences, Sultan Qaboos University, Muscat, Sultanate of Oman, His research area includes the application of GIS and Remote sensing in Geo-sciences, Natural Geo-Hazards and Environment. He is a member in many National and International Committees and Journal Editorial boards. He has been involved in many applied research projects, in various areas of Jordan, Saudi Arabia and Oman. He has more than 40 scientific paper and an article in the international scientific journals and in international conferences.

Abstract:

Many studies indicated the increase of the proportion of urban areas over the arable land in many provinces of the Sultanate Oman, this came as a result of urban growth and development processes taking place since the era of the Renaissance which started in 1970. Consequently, spatial variation in land use is an important issue to be taken in to consideration, because lands may be converted to be less productive, due to the lack of raw soil, vegetation and water. Moreover, the human exploitation of the limited resources in different ways, in addition to the natural factors of droughts and floods and urbanization all that will eventually lead to land degradation. Barka province (wilayat) in al Batinah Governorate one of provinces, which has been affected by land use, changes due to several reasons. Therefore, this study will focus on determination of land use changes, whether commercial or residential that have been occurred in the province, in addition to the loss of agricultural areas and fertile land during the period from 2010 to 2014. Remote sensing and geographic information system (GIS) were utilized in order to delineate and to determine the cause of shrinking in the arable land and fertile land. Satellite images were used to detect the change in land use/land cover by applying selective digital image processing techniques such as supervised classification and change detection. Thematic maps were prepared using GIS software with attribute data about the land uses in the study area, which highlight and show the impact of urban growth on land degradation.

Abstract:

Biofuels are fuels produced from any kind of biomass source, which could be the whole biomass like plants or wood, fermented biomass for biogas and biomethane or extracted products like fats and oils. There is a big variety of different fuels existing (Figure 1), however, the most developed fuels are bioethanol and biodiesel, which have been commercialized worldwide since over 20 years. There are many national and global mandates and incentives existing in order to promote biofuels; the main goal of these actions is the overall reduction of green house gas emissions. Advanced biofuels are fuels which lead to a significant reduction of greenhouse gases, e.g. fuels from waste and non food feedstocks, or are so-called drop in-fuels which could be used in higher blends in special applications like aviation fuels.

The paper gives an overview on the latest developments of technology and utilization of advanced biofuels but also describes the future and perspectives of biofuels. Especially the different legislations, e.g. the latest development of the European Directive of Renewable Energy are highlighted. As environmental issues like sustainability and life cycle assessment (LCA) have been discussed quite controversially, especially the food vs. fuel discussion, direct and indirect land use change, this presentation tries to evaluate the pros and cons to give a proper basis to evaluate the future potential of biofuels.

Biography:

Rania Mona Zeid Alqaralleh is a PhD candidate in the Department of Civil Engineering at the University of Ottawa, Canada. Her doctoral work investigates the thermophilic and hyper-thermophilic anaerobic co-digestion of thickened waste activated sludge and fat oil and grease (FOG), liquid portion of FOG (L-FOG) and organic fraction of municipal solid waste (OFMSW). Her research aims to improve the biogas production from solid organic waste using different waste combinations, pretreatment methods and thermal enhanced treatment.

Abstract:

In the light of climate change, environmental challenges and raising demand on energy, the quest toward developing renewable energy has become an urgent necessity. Renewable energy industries, investments, and related policies have been developed incredibly fast in the recent years [1]. A potential renewable energy source is biogas harvested from different types of organic wastes. Anaerobic digestion (AD) is one of the leading methods applied for generating biogas from organic waste. However, the biogas utilization in wastewater treatment plants (WWTPs) is still limited; for example, in the US less than 10% of the WWTPs produce biogas for beneficial use such as heat and power generation [2]. The WWTPs industry is facing real challenges in deploying the biogas production and utilization, such as; the slow biogas generation rate during the AD process, the low energy content (methane%) of the biogas, and the costs to upgrade the biogas [2,3]. In this study the anaerobic co-digestion of thickened waste activated sludge (TWAS) and the suitable organic wastes will be used to overcome some of the significant economic challenges by improving the AD process, increasing the biogas production with higher methane content, and reducing the final volume of waste. The feasibility of using hyper-thermophilic anaerobic co-digestion of TWAS, organic fraction of municipal solid waste (OFMSW), and fat, oil and grease (FOG) in producing biogas from solid waste will be established. The hyper-thermophilic co-digestion at high temperature (70ᵒC) has the potential to improve the anaerobic degradation of the organic waste mixture [4]. Whereas the use of OFMSW and FOG with the right concentrations will not only improve the C: N ratios in the digestion mixture leading to a significant increase in biogas production, but it also helps in converting these organic waste streams from landfills and that means increasing the lifespan of existing landfills and improving the sustainable development by improving waste to energy conversion.
