Surface barrier technology is used to isolate radioactive waste and to reduce or eliminate recharge water to the waste zone for 1000 years or longer. However, the design and evaluation of such a barrier is challenging because of the extremely long design life. After establishing a set of design and performance objectives, a package of design solutions was developed for 1000-year surface barriers over nuclear waste sites. The Prototype Hanford Barrier (PHB) was then constructed in 1994 in the field over an existing waste site as a demonstration. The barrier was tested to evaluate surface-barrier design and performance at the field scale under conditions of enhanced and natural precipitation and of no vegetation. The monitoring data demonstrate that the barrier satisfied nearly all objectives in the past two decades. The PHB far exceeded the Resource Conservation and Recovery Act criteria, functioned in Hanfords semiarid climate, limited drainage to well below the 0.5mmyr


LONDON--(BUSINESS WIRE)--According to the latest market study released by Technavio, the global industrial energy-efficiency services market is expected to grow at a CAGR of more than 6% during the forecast period. This research report titled ‘Global Industrial Energy-efficiency Services Market 2016-2020’ provides an in-depth analysis of the market in terms of revenue and emerging market trends. This market research report also includes up to date analysis and forecasts for various market segments and all geographical regions. One of the key drivers responsible for the growth of this market is the reduced greenhouse gas emissions through energy-efficient services. These solutions directly reduce the volume of fossil fuels consumed, thereby reducing all related emissions. Various global energy bodies have reported that energy-efficiency services will play a pivotal role in the movement towards making all industries eco-friendly. Other important drivers of this market are positive brand imaging and support from regulatory bodies for energy-efficiency services. This market is forecast to be valued at USD 10.18 billion by the end of the forecast period, according to Technavio analysts. Technavio’s sample reports are free of charge and contain multiple sections of the report including the market size and forecast, drivers, challenges, trends, and more. Based on service, the report categorizes the global industrial energy-efficiency services market into the following segments: “We expect the market for energy auditing and consulting to grow at a higher rate due to policymakers’ mandate for industries to undertake energy audits to identify opportunities for improving energy-efficiency. The Energy-Efficiency Directive formulated by the EU has mandated 20% reduction in energy use in power plants and large industrial facilities. The directive required all large enterprises in Europe to carry out energy audits every four years,” says Bharath Kanniappan, one of the lead analysts at Technavio for automation research. The global industrial energy-efficiency services market by energy auditing/consulting was responsible for generating revenue worth USD 3.21 billion in 2015 and is expected to reach USD 4.51 billion by 2020. This growth is likely to be driven by governments pushing for greener solutions. The UK has established a mandatory energy audit program, the Energy Savings Opportunity Scheme (ESOS). It mandates all large industrial facilities to identify, evaluate, and report energy-efficiency opportunities in their organizations every four years. Similarly, the Indian Energy Conservation Act mandates large energy-intensive industries to have energy audits and consulting by an accredited energy auditor. Industries have realized that just the presence of energy-efficient products and equipment does not guarantee the overall energy-efficiency of the industrial process. Any small misapplication or miscalculation can lead to a decrease in the overall efficiency of the process. Energy-efficiency companies help clients analyze, install, and streamline the workflow to achieve energy efficiency in a cost-effective manner. Product equipment vendors generally ensure that there is no loss in energy due to mechanical and thermal limitations and equipment inefficiency. Inefficient and inadequate pipes and installations in industrial plants which are responsible for the loss are optimized to save energy. There will be greater opportunities for equipment vendors across many industrial sectors to improve insulation capabilities of buildings, upgrade heating and cooling networks, and enhance metering and automation for efficacious heat systems. “Monitoring and verification is an integral part of any energy-efficiency services management program as they determine whether the energy-efficiency project has delivered the desired targets. The M&V market is growing because of increased adoption of various M&V protocols by industries as mandated by policymakers. China has developed stringent, robust, and sophisticated energy-efficiency M&V protocols to ensure optimal energy-efficiency,” says Bharath. Other nations are not far behind in implementing policies and guidelines. The US DOE has developed International Performance Measurement and Verification Protocol to increase the credibility of projections for the outcome of industrial energy-efficiency investments. This credibility can increase the confidence that investors and sponsors have in energy-efficiency projects, enhancing their chances of being financed.

Petroleum coke (petcoke) is an inexpensive potential fuel. However, its use has been limited because of the low volatile content and high sulfur contents. Moreover, research work has been extended for reducing the sulfur contents in petcoke. However, there is still no commercially established process of desulfurization of petcoke. Studies have been extended on the desulfurization of two petcoke samples. Interesting results were obtained by employing the techniques such as organorefining; that is, solvent extraction using N-methyl-2-pyrrolidone containing small amounts of ethylenediamine, morpholine, ethylenediamine, and other solvents. Acids and alkalis were also used for the desulfurization of petcoke. Biodesulfurization using Pantoea agglomerans D23W3 and Acidithiobacillus ferrooxidans showed interesting results. The present work also resulted in the development of some integrated processes of desulfurization of petcoke. Copyright © Taylor & Francis Group, LLC.

We study black hole solutions in Chern-Simons higher spin supergravity based on the superalgebra sl(3|2). These black hole solutions have a U(1) gauge field and a spin 2 hair in addition to the spin 3 hair. These additional fields correspond to the R-symmetry charges of the supergroup sl(3|2). Using the relation between the bulk field equations and the Ward identities of a CFT with N = 2 super- W3 symmetry, we identify the bulk charges and chemical potentials with those of the boundary CFT. From these identifications we see that a suitable set of variables to study this black hole is in terms of the charges present in three decoupled bosonic sub-algebras of the N = 2 super- W3 algebra. The entropy and the partition function of these R-charged black holes are then evaluated in terms of the charges of the bulk theory as well as in terms of its chemical potentials. We then compute the partition function in the dual CFT and find exact agreement with the bulk partition function. © 2013 SISSA, Trieste, Italy.

South Asia has witnessed a growing imbalance between energy demand and its supply from indigenous sources resulting in increased import dependence. Energy endowments differ among the South Asian countries. However, access to the significant energy resources in the neighboring countries is denied, which increases the cost of energy supply and reduces energy security of the individual countries and of the region as a whole. The countries in the region could benefit significantly only by strengthening the mechanism of energy trade through improved connectivity. Therefore, greater cooperation within South Asia could be one of the most effective ways to deal with this Regional Energy deficit and ensure Energy Security of the Region. © 2013 Elsevier Ltd.

India's ambitious goals for renewable energy raise many questions regarding the nature of investment required. We conduct financial modeling of actual renewable projects in India; and derive the following insights. First, the high cost of debt is the most pressing problem: higher cost and inferior terms of debt in India may raise the cost of renewable energy by 24-32% compared to the U.S. Second, even if cost of debt goes down, loan terms - including short tenors and variable interest rates - will become significant impediments, given that they add 13-14% to the cost of renewable energy in India compared to the U.S. Finally, due to the high cost of debt, policy lessons from the U.S. and Europe; which focus on finer instruments such as duration of revenue-support, revenue-certainty, investor-risk-perception, and completion/cost-certainty; are not likely to be as effective, with potential impacts on the cost of renewable energy in the 3-11% range. In fact, we find that an interest-rate subsidy, which reduces the cost of debt, reduces the overall subsidy burden by 13-16%. This suggests that Indian policymakers need to prioritize the provision of low-cost, long-term debt and take a closer look at the successful efforts by China and Brazil. © 2013 Elsevier Ltd.

Abstract In India, the National Action Policy on Climate Change (NAPCC)1 has set a target of 15% of electricity via renewable energy sources by 2020. To reach these ambitious targets, in March 2011, the Government of India launched the renewable energy certificates (REC) - a market based mechanism - to drive renewable energy development and spur further investments. However, a look into the actual performance of REC market trading during the first year of operation shows that, though volume of trading steadily increased, the number of accredited certificates issued was less than 2.5% of the technical REC demand potential, indicating that the full potential of the REC markets was far from being realized. We critically examine the design and implementation of the REC market in India as well as its effectiveness in meeting the desired objectives in the context of international best practices. Our analysis of REC market best practices reveals that, though forward markets, banking and price bounds are recommended for stable markets, best-of-class methods for determining the optimal length of banking, the level of floor and forbearance prices, and the values of credit/vintage multipliers are not fully established. We then establish that the main issues with the Indian REC markets appear to be demand uncertainty resulting from lack of long term targets, absence of clarity on compliance, and near-absence of long-term price signals to investors. Finally, we present an analysis of other important features of the Indian REC market in the context of well-functioning REC markets, such as credit-multipliers/set-asides, vintage multipliers, and voluntary markets. © 2013 Elsevier Ltd.

India’s largest power trading platform, Indian Energy Exchang,e is planning to set up a dedicated trading platform for renewable energy. In a recent interview, officials of Indian Energy Exchange (IEX) stated that they are planning to introduce a dedicated power exchange for renewable energy projects. The officials stated that since the government plans to have 175 GW of renewable energy installed by March 2022, project developers will likely look to have multiple options to sell their electricity. The idea of a dedicated renewable energy trading platform will work only if private sector project developers look to set up projects outside the tenders floated by the state and central governments. Developers winning such tenders have to sign long-term power purchase agreements, leaving them with no alternate options to sell electricity. This sometimes becomes a financial hurdles for the developers as not all off-takers are of sound financial condition to make regular payments to the developers. The success of a renewable energy trading platform will be a challenge, as distribution companies in India are not buying renewable energy certificates which help them meet their renewable purchase obligation. Several million such certificates currently remain unsold, with distribution companies not heeding the pleas of the Ministry of New & Renewable Energy to rapidly increase the purchase of these certificates. Indian Energy Exchange is looking to promote this dedicated platform as an alternate venue for project developers to sell electricity and keep their projects financially viable in case long-term agreements do not provide the desired revenue.   Drive an electric car?
