Mineral Matter Behavior During The Combustion Of Biomass And Coal Blends And Its Effect On Particulate Matter Emission, Ash Deposition, And Sulfur Dioxide Emission, Rajarshi Roy
Theses and Dissertations
Combustion of coal is one of the primary sources of electricity generation worldwide today. Coal contains different chemicals that cause particulate matter(PM) and sulfur dioxide (SO2) emissions. These are health hazards and are responsible for deteriorating the ambient air quality. Particulate matter also forms ash deposits inside the coal combustor, which in turn decreases the energy efficiency of the power plants. Using biomass as a fuel in these utility boilers can potentially reduce the problems of particulate matter emissions and ash deposition, and can significantly reduce the SO2 emissions. However, biomass needs to be pretreated to make its properties similar …

Faculty Publications
In this study, a nuclear hybrid energy system (NHES) with large-scale hydrogen storage integrated with a gas turbine cycle is proposed as a flexible system for load following. The proposed system consists of a nuclear reactor, a steam Rankine cycle, a hydrogen electrolyzer, a storage system for hydrogen in an underground salt cavern, and a Brayton cycle that uses hydrogen as fuel to generate additional electricity to meet peak demand. A dynamic mathematical model is developed for each subsystem of the NHES. To evaluate the potential benefits of the system, a one-year study is conducted, using scaled grid demand data …

Theses and Dissertations
One approach to enabling a larger penetration of renewable sources of energy is the implementation of hybrid power plants. This work presents a process to determine the preliminary optimal configuration of a concentrating solar power-coal hybrid power plant with low solar augmentation, and is demonstrated on a coal power plant in Castle Dale, UT. A representative model is developed and validated against published data for a coal power plant of a different configuration than Hunter Unit 3. The simplifications within the representative model include combining multiple feedwater heaters, combining turbines that operate across the same boundary states, and the mass-average …
Ferritin-Based Photo-Oxidation Of Biomass For Nanoparticle Synthesis, Bioremediation, And Hydrogen Evolution, Oscar Petrucci
Ferritin-Based Photo-Oxidation Of Biomass For Nanoparticle Synthesis, Bioremediation, And Hydrogen Evolution, Oscar Petrucci
Theses and Dissertations
The cell is the basic unit of all living organisms. It is an amazing machine capable of self-replicating, growing, and synthesizing and shuttling thousands of compounds. To perform all of these activities the cell needs energy. The original source of energy for all living beings is the Sun. The energy of the sun is collected by the autotrophs (mostly plants) through photosynthesis and stored in the chemical bonds of carbohydrates and lipids through carboxylic acid intermediates; animals use these compounds to obtain the energy for their cells. Most of the energy extracted by the cell comes from the citric acid …

Linked Data In Renewable Energy Domain, Henry Abanda, Joseph Tah
International Congress on Environmental Modelling and Software
The vision of the Semantic Web is to build a global Web of data that links different resources. To this end, the first step is to put data on the Web in the form that machines can naturally understand or convert to useful forms. This can be achieved through Linked Data technology, an emerging publishing paradigm in which not only documents, but also data are linked over the Web. The ultimate goal underpinning Linked Data is to enable different individuals and organisations to efficiently contribute and share data about different domains. Climate change impacts and/or energy scarcity are among the …

Integrated Model Platform For Sustainable Energy Planning. Colombian Case., R. Quijano, J. Domínguez
International Congress on Environmental Modelling and Software
Colombia has relied for long on a generous endowment of fossil fuels (oil, coal and gas) and hydropower to meet domestic energy needs and also to contribute substantially to the balance of trade in international markets. But this situation is about to change due to the announced loss of self-sufficiency in oil (forecasted by 2010-2011) unless a dramatic last minute change in proven reserves occurs. Likewise, Colombia’s hydro potential (the largest energy source for power generation in the country) is facing difficulties to add further representation within the generation mix. These difficulties include increasing environmental and social costs associated with …

Forest Biomass Sustainable Use For Energy Production: A Dynamic Optimization Problem, F. Frombo, R. Minciardi, M. Robba, F. Rosso, Roberto Sacile
International Congress on Environmental Modelling and Software
The use of forest biomass for energy production requires a careful attention to the sustainable silvicultural practices that can guarantee the satisfaction of the environmental constraints, the control of the forest growth, the carbon stock, and the CO2 emissions. This is a complex task because of the different environmental and economic issues (related to the characteristics of the territory, the energy demand, the forest biomass potential production, and the techniques for forest utilization) to be taken into account. Environmental Decision Support Systems (EDSS) are considered as valuable tools for the planning and management of renewable resources use for energy production. …

International Congress on Environmental Modelling and Software
During the last years an increasing energy demand, rising prices for fossil fuels, thechallenge of meeting the objectives of the Kyoto protocol as well as a certain uncertainty ofenergy supply resulted in the two main aspects arising within the design of our futureenergy system, which are sustainability and security of supply.To meet these challenges, the paper presents a modelling approach that handles informationon geographically disaggregated data of renewable energy potentials as well asgeographically disaggregated information on energy demand structures. The comparison ofthe identified energy potentials of the modelling process to the relative energy consumptionstructure results in a “balance grid” that …
Multi Criteria Evaluation Of Low Carbon Energy Technologies, S. Mandera, C. Gough
Multi Criteria Evaluation Of Low Carbon Energy Technologies, S. Mandera, C. Gough
International Congress on Environmental Modelling and Software
Achieving a low carbon energy supply in a future society driven by the impacts of climate change will require huge technological changes. This paper compares the methodological implications of assessing two very different technological solutions – renewable energy and geological carbon sequestration. The UK has high renewable resources, in particular the highest wind resource in Europe. In contrast, atmospheric emissions from fossil fuels could be avoided by storing carbon dioxide in underground geological formations for which the UK has a huge potential capacity. These two technological approaches will have diverse and wide ranging impacts; both inspire views amongst stakeholders that …

A decision support system for forest biomass exploitation for energy supply is presented. In the proposed approach, geographic information system based techniques are integrated with mathematical programming methods yielding a comprehensive system, which allows formalizing the problem, taking decisions, and evaluating their effects. The aim of this work is to evaluate the possibility of biomass exploitation for both thermal and electric energy production in a provincial area. The decision support system is able to locate and size different kinds of plants on the territory (defining which kind of energy is convenient to produce for the specific area), take into account …
Estimating Tradeable Certificates Created By Small-Scale Renewable Energy Systems, Trevor Pryor, Clinton Watkins, Heath Lang
Estimating Tradeable Certificates Created By Small-Scale Renewable Energy Systems, Trevor Pryor, Clinton Watkins, Heath Lang
International Congress on Environmental Modelling and Software
Recent industry development programs in several countries have involved the use of tradeable certificate schemes as means for electricity generators and retailers to fulfil mandatory requirements for renewable energy generation. Renewable energy generation will potentially also yield carbon offsets under domestic emissions constraints involving emissions trading schemes. This paper develops a novel framework for estimating the amount of renewable energy certificates and carbon emissions offsets that may be created by a wide range of small scale renewable energy systems. A methodology is developed that requires information on only two parameters of the generating system, namely the specific fuel consumptions of …
