Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 790-803

Abstract: Generation expansion planning consists of finding the optimal long-term plan for the construction of new generation capacity subject to various economic and technical constraints. It usually involves solving a large-scale, non-linear discrete and dynamic optimisation problem in a highly constrained and uncertain environment. Traditional approaches to capacity planning have focused on achieving a least-cost plan. During the last two decades however, new paradigms for expansion planning have emerged that are driven by environmental and political factors. This has resulted in the formulation of multi-criteria approaches that enable power system planners to simultaneously consider multiple and conflicting objectives in the decision-making process. More recently, the increasing integration of intermittent renewable energy sources in the grid to sustain power system decarbonisation and energy security has introduced new challenges. Such a transition spawns new dynamics pertaining to the variability and uncertainty of these generation resources in determining the best mix. In addition to ensuring adequacy of generation capacity, it is essential to consider the operational characteristics of the generation sources in the planning process. In this paper, we first review the evolution of generation expansion planning techniques in the face of more stringent environmental policies and growing uncertainty. More importantly, we highlight the emerging challenges presented by the intermittent nature of some renewable energy sources. In particular, we discuss the power supply adequacy and operational flexibility issues introduced by variable renewable sources as well as the attempts made to address them. Finally, we identify important future research directions.

Direct use of waste vegetable oil in internal combustion engines

Author
D. CapuanoM. CostaS. Di FraiaN. Massarotti and L. Vanoli
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 759-770

Abstract: Direct use of Waste Vegetable Oil (WVO) as fuel is very attractive to reduce fossil fuels utilization and increase sustainability. WVO incorrect disposal causes serious damages to sewage systems and wastewater treatment plants. Moreover, if WVO reaches natural ecosystems, such as rivers, aquifers or subsoil, the environmental consequences can be severe. In recent years, the main reuse of WVO has been in biodiesel production, which is remunerative under current tax allowance policies. However, biodiesel production requires complex physical–chemical treatments, while direct use of WVO just needs mechanical treatment. As a consequence, WVO direct use in energy conversion systems lower the impact, from the economic, energetic and environmental points of view, with respect to biodiesel production. Moreover, as concerns the environmental impact, it should be considered that the direct use of WVO as fuel produces less polluting emissions when considering the whole life cycle: carbon dioxide produced during combustion, in fact, can be partially absorbed by crops used for oil production.

Energy overview for globalized world economy: Source, supply chain and sink

Author
G.Q. Chen and X.F. Wu
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 735-749

Abstract: Energy use of the globalized world economy is comprehensively overviewed by means of a systems input-output analysis based on statistics of 2010. Emphases are put on the sources of primary energy exploitation, inter-regional trade imbalance of energy use via global supply chains, and sinks of energy use in final demand. The largest final user turns out to be the United States, compared with China as the leading energy exploiter. The global trade volume of energy use is shown in magnitude up to about 90% of the global primary energy exploited. The United States is recognized as the world’s biggest energy use importer, in contrast to Russia as the biggest exporter. Approximately one third of global primary energy exploited is shown to be embodied in inter-regional net trade. Japan and Russia are respectively illustrated to be the world’s leading net importer and leading net exporter of energy use. For China as the leading energy exploiter, about 30% of its exploited energy is for foreign regions’ final use, and 70% for its own final use. For the European Union as the largest sink region, nearly 80% of the energy required in its final use is from foreign regions, led by Russia. As reflected in the results, the conventional perspective based only on the direct energy consumption by region inevitably leads to inter-regional “energy grabbing” and “carbon leakage”, which raises a serious concern of “regional decrease at the expense of global increase”. In current context of energy shortage and climate change, this global energy overview can provide essential strategic implications at the international, national and regional scales for sustainable energy policy making.

A comprehensive review on biomass and solar energy for sustainable energy generation in Nigeria

Author
Adewale GiwaAdetunji AlabiAhmed Yusuf and Tuza Olukan
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 620-641

Abstract: Nigeria is the most populous country in Africa (7th most populous in the world) and it is strategic to the realization of the United Nations’ Sustainable Development Goals (SDGs) by 2030. However, SDG No. 7 (affordable and clean energy) and other goals connected to the reduction of climate change are crucial for the attainment of sustainable development in Nigeria. This comprehensive review encompasses the discussions of the clean energy potential, obstacles to and stimulants of clean energy implementations, and renewable energy policies in Nigeria. Solar and biomass resources have been presented in this article because of their huge availability in Nigeria. Nigeria has the potential to produce an estimated 47.97 million tonnes of oil equivalent (MTOE) annually from biomass resources. Likewise, 17, 459 billion MJ/day of solar energy is incident on the total surface of Nigeria. The biomass resources which can be tapped for renewable energy production in Nigeria include Jatropha with high oil contents, sweet sorghum and molasses; food crops such as cassava, rice, coconut, cashew, millet, rice, oil palm, maize, and yam; agricultural residues and wastes from food crops such as cassava peels, cassava liquid sludge, mango peel, mango seed kernel, rice husks (RH), corn residues, oil palm derivatives, sugar cane straw, and bagasse; forest resources; municipal solid wastes; and animal wastes. These resources can be exploited for the production of biogas, bioethanol, biodiesel, briquettes and organic fertilizers through anaerobic digestion, transesterification, gasification, pyrolysis, and briquetting. There are also huge potentials for the deployment of solar photovoltaic (PV) and thermal systems in off-grid, grid-connected, and hybrid installations. It can be concluded that the techno-economic feasibility and environmental significance of solar power and bioenergy for Nigeria’s sustainable development is site-specific and subject to factors such as incentives and financing, research and development, public enlightenment, government’s policies, and private investments.

A review of multi criteria decision making (MCDM) towards sustainable renewable energy development

Author
Abhishek KumarBikash SahArvind R. SinghYan DengXiangning HePraveen Kumarand R.C. Bansal
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 596-609

Abstract: In the current era of sustainable development, energy planning has become complex due to the involvement of multiple benchmarks like technical, social, economic and environmental. This in turn puts major constraints for decision makers to optimize energy alternatives independently and discretely especially in case of rural communities. In addition, topographical limitations concerning renewable energy systems which are mostly distributed in nature, the energy planning becomes more complicated. In such cases, decision analysis plays a vital role for designing such systems by considering various criteria and objectives even at disintegrated levels of electrification. Multiple criteria decision making (MCDM) is a branch of operational research dealing with finding optimal results in complex scenarios including various indicators, conflicting objectives and criteria. This tool is becoming popular in the field of energy planning due to the flexibility it provides to the decision makers to take decisions while considering all the criteria and objectives simultaneously. This article develops an insight into various MCDM techniques, progress made by considering renewable energy applications over MCDM methods and future prospects in this area. An extensive review in the sphere of sustainable energy has been performed by utilizing MCDM technique.

Cyanobacterial factories for the production of green energy and value-added products: An integrated approach for economic viability

Author
Rajneesh,Shailendra P. SinghJainendra Pathak and Rajeshwer P. Sinha
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 578-595

Abstract: Cyanobacteria are Gram-negative photosynthetic prokaryotes and are well known for their role in global carbon dioxide and nitrogen fixation. Recent developments in synthetic biology and metabolic engineering tools for these prokaryotes have allowed designing of novel metabolic pathways in these organisms which makes them potential candidates for the commercial production of fourth generation of biofuels. However, cost associated with large scale cultivation, harvesting, downstream processing and continued decrease in the price of crude oil in recent years has threatened the economic viability of biofuels production at commercial level. Cyanobacteria are known to produce wide range of secondary metabolites having biotechnological, biomedical and industrial importance. Cyanobacterial secondary metabolites can be industrially exploited as natural sunscreens, algaecides, herbicides, insecticides, antibiotics, antifungal, immunosuppressant, anticancer, antiviral and anti-inflammatory agents. Here, we propose an integrated approach for economic viability of biofuel production using cyanobacterial chassis by combining the production of value-added products synthesized by these organisms to attain a reasonable price for biofuels per barrel which can compete with current and/or future market price.

Renewable energy investment and job creation; a cross-sectoral assessment for the Czech Republic with reference to EU benchmarks

Author
Petr DvořákStanislav MartinátDan Van der HorstBohumil Frantál and Kamila Turečková
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 360-368

Abstract: The development of renewable energy sources has been primarily justified on the ground of environmental policies and energy security, but new jobs opportunities and establishment of new economy sectors may be equally important co-benefits from investments in this sector. The main goal of this paper is to assess the employment benefits of investments in renewable energy in the Czech Republic. We examine the level and rate of the development of the renewable energy sector in the Czech Republic in terms of ('green‘) job creation for the period 2008–2013, in comparison to data from other EU countries, including Germany as a leading early investor in renewables. Whilst the deployment of renewable energy in the Czech Republic has succeeded to create a significant number of jobs (more than 20 000 employees in 2010), our analysis illustrates a strong dependency of job creation on the continuation of financial incentives. We also find that biomass and waste energy processing offer the highest employment per MWh, which benefits employment in (economically fragile) rural areas. We discuss the question of competitiveness of a country that was not amongst the early adopters of renewables, arguing that the technical skills of the labour force in the Czech Republic provide a potential for more sustained investments in the sector.

Key challenges and requirements for sustainable and industrialized biorefinery supply chain design and management: A bibliographic analysis

Author
Andrea Teresa Espinoza PérezMauricio CamargoPaulo César Narváez Rincón and Miguel Alfaro Marchant
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 350-359

Abstract: The growing global population and its effects on world food security, as well as the urgency for climate change mitigation, are issues that foster technological, social, and political innovations to increase the efficiency of use of natural resources, such as biomass among others. While significant research efforts have been devoted to biomass conversion processes, their associated supply chains and their implication for complete process efficiency have only been studied more recently. However, most of the recent investigations into the design and optimization of biomass supply chains have focused on an economic point of view, sidelining other dimensions of sustainability, which represents a serious drawback for this kind of work. This article surveys the recent research on design and management optimization of biorefinery supply chains from a sustainability perspective. 72 published research articles from 2006 to 2015 have been analyzed to highlight the sustainability dimensions considered, as well as the inclusion of uncertainties. A typology of decision-making at three levels of analysis (strategic, tactical and operational), and the specific set of tools used to model and optimize the biorefinery supply chain have also been studied. The conclusion underlines the contributions and shortcomings of current research and suggests possible future directions.

Intention of agricultural professionals toward biofuels in Iran: Implications for energy security, society, and policy

Author
Ziba BakhtiyariMasoud YazdanpanahMasoumeh Forouzani and Navab Kazemi
Renewable and Sustainable Energy Reviews, 2017, vol. 69, issue C, pages 341-349

Abstract: This research applies the Health Beliefs Model (HBM) as a framework for understanding the intentions of agricultural professionals with respect to biofuels. We argue that it is essential to understand these intensions as agricultural professionals play critical role as educators, gatekeepers, and stakeholders in the agricultural domain. A face-to-face survey was undertaken in South Western Iran using a multi-stage, stratified random sample of agriculture professionals (n=288). The reliability and validity of the instruments were examined and approved. Structural equation modeling showed that general beliefs regarding fuels and biofuels, perceived benefits, perceived severity, self-efficacy, and cue to action are significant predictors of professionals’ willingness to support biofuels. These variables can predict nearly 43% variance in professionals’ willingness. The findings yield public policy implications for biofuel use and development support among professionals and provide preliminary support for the HBM as an effective framework for examining intention toward biofuels among agriculture professionals in Iran.
