Technical and economic characteristics of eliminating carbon-dioxide emission

This paper deals with the technological and economic (cost) parameters of the release, capture and storage of the carbon dioxide in the flue gases of fossil fuel (coal, natural gas) fired power plants. It makes comparisons and generalisations through processing a wide range of data quoted from the literature. As the first step, the topicality of the issue is justified by illustrating the role of fossil fuels in the energy supply of the more remote future with forecast data. During the technological development of power plants in the last 50 years, block capacity has increased considerably, 5-8 times, with thermal capacity increasing by 50- 60%, as a result of which specific carbon dioxide release has decreased by 30-40%. The paper briefly refers to the theoretical possibility of the sequestration of the carbon dioxide captured from flue gases in geological formations. The enhancing effects of the implementation of CO₂ capture on investment costs and its reducing effect on net power plant output and utilization (thermal) efficiency are also analysed in the paper. The efficiency of CO₂ capture and the parameters of atmospheric carbon dioxide emission are also given attached to fuel types and technological solutions. As a parameter of the technological solutions, it is indicated what specific cost (USD/tCO₂) is demanded for CO₂ capture or avoidance, and to what extent it raises the costs of electricity production.

Social Barriers to Renewable Energy Landscapes

After many years of slow progress, we find that worldwide environmental, political, and economic pressures are providing greater purchase for the accelerated development of renewable energy. Although many people would consider this quickening pace good news, the transition from conventional resources has encountered public resistance. In this article I examine the nature of challenges to the development of geothermal, wind, and solar energy projects in three places: the United States, Scotland, and Mexico. The common thread in the public reservations about renewable energy is landscape change and the consequent disruption such change produces to established ways of life for those who are nearby. It also suggests the importance of rebalancing the emphasis of renewable energy programs away from the traditional technical focus that dominates development planning. The more suitable and expedient approach would be to consider the challenges of development as predominantly social matters with technical components, rather than the other way around. To accept this view is to unlock the door to a renewable energy future.

Agave for tequila and biofuels: an economic assessment and potential opportunities

This paper explores the economic viability of producing biofuels from Agave in Mexico and the potential for it to complement the production of tequila or mescal. We focus on Agave varieties currently being used by the tequila industry to produce two beverages, tequila and mescal, and explore the potential for biofuel production from these plants. Without competing directly with beverage production, we discuss the economic costs and benefits of converting Agave by-products to liquid fuel as an additional value-added product and expanding cultivation of Agave on available land. We find that the feedstock cost for biofuel from the Agave piña alone could be more than US$3 L⁻¹ on average. This is considerably higher than the feedstock costs of corn ethanol and sugarcane ethanol. However, there may be potential to reduce these costs with higher conversion efficiencies or by using sugar present in other parts of the plant. The costs of cellulosic biofuels using the biomass from the entire plant could be lower depending on the conversion efficiency of biomass to fuel and the additional costs of harvesting, collecting and transporting that biomass.
