Energy Sources Of Renewable Biomass - 962 Words

I. INTRODUCTION As an abundant, inexpensive, and renewable as well as environmentally-friendly (i.e. CO2-neutral) energy source, biomass energy has been a particular focus of researcher and policy makers as well as industries around the world (Chen, 2003). Renewable biomass presents an important research area for energy source, considering the current global crises of exhaustible sources of energy. Bioenergy is the 4th largest source of energy in the world, and it does not contribute to the global warming through emissions of CO2 or any other green-house gases. Biomass pyrolysis has witnessed exponential growth in its research and has been investigated extensively in the last few decades, first in the form of fixed bed reactors and later in the form of moving bed reactors (fluidized bed, auger bed etc). As the combustion of solid biomass is analogous to the combustion of other solid fuels, such as coal and waste, essentially the same technology is applicable to all solid fuels, although modification s are required to handle the high content of moisture and volatiles typically associated with biomass fuels (Duffy Eaton, 2013). In this paper, which reviews the computational fluid dynamics (CFD) analysis of fixed/moving bed solid-gas reactors, biomass pyrolysis, gasification and combustion has been the focus of the study. Combustion of biomass in the presence of carrier gases like N2 etc has been extensively studied, with focus being on the numerical or CFD models which haveShow MoreRelatedBiomass And Renewable Sources Of Energy2192 Words   |  9 PagesExecutive summary Biomass has become one of the most commonly used renewable sources of energy in the last two decades. Many of the biomass fuels used today come in the form of wood products, dried vegetation, crop residues, and aquatic plants. It is such a widely utilized source of energy, probably due to its low cost and indigenous nature, that it accounts for almost 14% of the world s total energy supply and as much as 35% in developing countries, mostly for cooking and heating. The wood fromRead MoreSustainability And Construction Practices : Department Of Civil Engineering1256 Words   |  6 Pages 3 Scope of renewable energy 3 Types of renewable energy i. Solar power 3 ii.

Due to high demand of fossil fuels, the air is filled with more pollution every day. In addition to, it can increase the chances of having global warming. Since fossil fuels are generated from raw materials which are easy and cheap users are becoming extremely dependent on them. The main problem with fossil energy is that the supply of fossil fuels is notRead MoreRenewable Energy Sources For Fossil Fuels1240 Words   |  5 Pagesorder to provide us energy. Almost everything we use nowadays consumes power in some form, and in tandem we rely on energy. Fossil fuels have become the go to resource for providing power. Fossil fuels include natural resources such as coal, petroleum, and natural gas. These fossil fuels fall under the non-renewable category because they take thousands of years in order to form naturally and cannot be replaced as fast as they are being cons umed. Another non-renewable energy source is nuclear fuel, whichRead MoreBiomass Essay1094 Words   |  5 Pagesresidue biomass is highly recommended as clean and renewable sources of energy that increases the possibility of replacing the consumption of conventional energy fossil fuels. The objectives of this review report is to evaluate the processes how briquettes are produced from agricultural wastes/residues and To compare the intensity of greenhouse gas emission using briquettes of agricultural wastes/residues with other forms of energy sources especially fossil fuels. Thus agricultural residue biomass energyRead MoreBiomass As A Renewable Energy Resource907 Words   |  4 Pages3 Biomass as a renewable energy resource Biomass can be considered as a renewable energy resource, although burning biomass releases carbon dioxide (CO2) to the atmosphere similar to burning fossil fuel (Liu H. 2011). There is a significant difference in CO2 release between burning a fossil fuel and burning biomass. Burning a fossil fuel releases CO2 that has been locked up for millions of years in the ground, affecting the natural CO2 cycle and resulting in an increase in the CO2 concentration inRead MoreAlternative Energy: Solar Energy1323 Words   |  5 PagesIn the world today, alternative energy source which is an alternative to fossil fuel and nuclear energy is becoming more and more of a necessity. Right now, the world’s population growth has caused an increase in the energy demand. Rosenberg (2009) pointed out that the world’s current growth rate is about 1.14%, representing a doubling time of 61 years. OECDs International Energy Agency[IEA] (2014) found that from 2011 to 2035 the world energy demand is likely to rise by more than two-thirds. ThoughRead MoreThe world depends heavily on fossil fuels such as coal, oil, and natural gas for energy, and while700 Words   |  3 Pagesnatural gas for energy, and while the worlds population and energy consumption continue to increase, the non-renewable resources we need to produce energy will eventually be depleted. According to the U.S. Energy Information Administration, the supply of oil left in the world will last us twenty five more years. One may say that twenty five years is a long time, and by then new sources of fuel will surely have replaced the nonrenewable sources we currently use to meet our energy demands. This, howeverRead MoreRenewable Energy Sources And The Global Warming1503 Words   |  7 PagesRenewable energy sources Let’s ask ourselves that when the erosion able elements of the earth is not achievable anymore and the glob is getting warmer day by day, what we are going to do to satisfy our requirements, and wants? How we can reduce global warming, decrease the negative impacts of greenhouse gas emission? What are some other natural origins by which we can continue our lives without hurting other existences in the earth? All these problems can be solved if we use renewable energy sourcesRead MoreRenewable Energy Resources In Thaille Essay1552 Words   |  7 Pages Brunei is targeting to utilize 0.6% of renewable energy consumption into the country’s final energy consumption by 2035. Yet, oil will still account for the largest share (46%), followed by gas (35%) and electricity (19%). Natural gas and oil will remain the dominant supply fuels for primary energy with small contributions from new renewable energy which is solar and biomass. Currently, the economy already has a 1.2 MW solar power plant and will continue to develop more solar capacity during the
