Description:
This paper examines the impacts of wind power generation on the future choice of fuels and technologies in the power sector of Vietnam. The study covers a time frame of 20yr from 2005 to 2025 and the MARKAL model has been chosen to be adaptable to this specific task. The results of the study show that on a simple cost base, power generated from wind is not yet competitive with that of fossil fuel-based power plants. In order to make wind energy competitive, either carbon tax or an emission reduction target on the system must be imposed. The presence of wind power would affect not only the change in generation mix from coal-based power plants to wind turbines but also an increase in the capacity of other technologies which emit less carbon dioxide. It thus helps reduce fossil fuel requirement and consequently enhances energy security for the country. The study also shows that wind turbine in Vietnam could be a potential CDM project for annex I party countries. ... Read more

Description:
Kuwait is using only MSF desalting system coupled to steam turbines to desalt seawater. There is shortage in desalting capacity, and 180 MIGD desalting units have to be installed within 5 years. Meanwhile there are not enough operating steam turbines to supply steam to desalting units if MSF units are chosen. At the same time there are peak load gas turbines (GT) that are usually operated for very short times, only 16 h in the year 2001 as example. Also Kuwait is planning to have 400-MW total capacity GT just to be operated at peak load. These GT can be used to operate reverse osmosis (RO) desalting system, when not needed to carry load. Other desalting types can be added, beside the RO system, to produce water more efficiently, energy wise than the presently used method. Forming combined gas/steam cycles by adding steam turbines to these GT increases the installed power capacity, efficiency of power production, and ability to produce more water. This paper presents some variants of combining GT with desalting systems. These variants use standard, well-proven type and reliable equipment, besides being more energy efficient compared to MSF units combined with stearn turbines. ... Read more

excellent
Finally someone wrote a book that also treats the interface from the solar cell to the operating conditions in a real environment.
Very nice are also the LCAs (including energy (and CO2) payback via recyling) for different sites of application.

Energy supply via photoelectric power generation - globally
This book explores the real potential of solar electric power generation in order to reduce CO2 emissions and prevent the planet from global warming. For this purpose the author analyses the entire energy balance of photovoltaic power plants during their life time from the production to the recycling - taking into account the whole system. He considers all optical interfaces and layers passed by the sunlight from the sun into the solar cell, thermal layout of any photovoltaic module and its heat transfer mechanisms, its related actual electrical properties, allowing an accurate calculation of yield and an optimization of system components, thus reducing costs for solar electricity. Different locations for production and installation of photovoltaic systems are also considered. The concluding message is: If applied in an intelligent way, global energy supply via photo-electric power generation is widely possible. ... Read more

Description:
Electricity generation by individual households (known as micro-generation) is attracting an increasing amount of interest within government, industry and the research community. This paper focuses on the potential for micro-generation to contribute to a more active role for household energy consumers in the development and operation of the energy system. The paper applies the concept of energy service co-provision to aid an understanding of this more active role. It considers a number of alternative models for micro-generation investment that imply different kinds of co-provision by consumers and energy companies. The analysis focuses in particular on the economics of these models in the UK, the associated barriers to micro-generation investment, and the scope for overcoming these barriers through changes in fiscal rules. Having conducted this economic analysis, the paper concludes with a brief discussion of the wider implications of these models for consumer behaviour. In particular, it considers the impact of IT and control systems that might be employed to facilitate energy service co-provision that includes micro-generation. ... Read more

Description:
This paper explores how investment in the UK electricity generation sector can contribute to the UK goal of reducing CO"2 emissions with 60% by the year 2050 relative to the 1990 emissions. Considering likely development of the transportation sector and industry over the period, i.e. a continued demand growth and dependency on fossil fuels and electricity, the analysis shows that this implies CO"2 emission reductions of up to 90% by 2050 for the electricity sector. Emphasis is put on limitations imposed by the present system, described by a detailed database of existing power plants, together with meeting targets on renewable electricity generation (RES) including assumptions on gas acting as backup technology for intermittent RES. In particular, it is investigated to what extent new fossil fuelled and nuclear power is required to meet the year 2050 demand as specified by the Royal Commission on Environmental Pollution (RCEP). In addition, the number of sites required for centralized electricity generation (large power plants) is compared with the present number of sites. A simulation model was developed for the analysis. The model applies the UK national targets on RES, taken from Renewable Obligation (RO) for 2010 and 2020 and potentials given by RCEP for 2050, and assumed technical lifetimes of the power plants of the existing system and thus, links this system with targets for the years 2010, 2020 and 2050. The results illustrate the problem with lock-in effects due to long capital stock turnover times, which can either lead to political difficulty meeting targets in established policy or costly early retirement of power plants (stranded assets) to comply with emission goals prescribed in Kyoto targets or the 60% emission reduction goal. Assuming typical technical lifetimes of the power plants it can be concluded that the present electricity generation system continues to play a significant role for several decades generating about 50% of projected electricity demand in 2025. In addition, the results show that although the high degree of fuel switch from coal to natural gas which has taken place in the UK over the last decade (which seems to continue) which enables the UK to fulfill the Kyoto target, the resulting dependency on gas gives a more or less constant level of CO"2 emissions between 2010 and 2020. Hence, meeting stricter abatement targets in a second Kyoto period requires emission reductions in other sectors or penetration levels of RES faster than prescribed in the RO. ... Read more

Description:
It is necessary to know CO"2 source generation rates and system flow parameters, such as supply flow rate and overall room ventilation effectiveness, in order to evaluate cost savings for demand-controlled ventilation applied to commercial buildings. This paper presents a methodology for estimating schedules for generation rates and flow parameters using short-term testing. These parameters are used within a model that predicts return air CO"2 concentrations as part of an overall energy analysis model. As a first step in developing the methodology, two different parameter estimation techniques were evaluated using simulated data. Each method gave models that provide good predictions of return air CO"2 concentrations, but differed in terms of the identified parameters. The preferred parameter estimation method provides estimates of both average hourly source generation rates and day-to-day variations. This technique was applied to three different types of commercial buildings using field monitored data. The sites are small commercial buildings with packaged HVAC equipment and included modular schoolrooms, children's play areas in fast food restaurants and a pharmacy retail store. The impact of the length of model training data period on estimated CO"2 generation rates was investigated. Eight weeks of data is sufficient for training. Expressed in terms of the coefficient of variation, the errors in predicted CO"2 concentrations ranged from 4% to 15% depending on the sites. The predicted frequency of time that CO"2 concentrations were within a given range agreed well with the field measured data. ... Read more

Description:
The energetic utilisation of agricultural residues is considered to be an important element in any strategy to achieve renewable energy targets. In the approximately 80 cane-sugar producing countries there is potential to make better use of the fibrous residue known as bagasse. Subject to improved energy efficiency, sugar producers could supply energy either as ''green'', co-generated electricity, or as fuel ethanol through cellulose hydrolysis followed by fermentation. This paper compares their projected environmental benefits from a life-cycle perspective, using South African data. Mass and energy analyses were prepared for the two systems and a base case (producing sugar with current methods), relative to the annual sugarcane production on one hectare. In both cases, the environmental burdens avoided by replacing an equivalent amount of fossil energy were included. The results obtained confirm that for all the impact categories considered, both ''bioenergy'' products result in environmental benefits. The co-generation option results in lower energy-related emissions (i.e. lower global warming, acidification and eutrophication potentials), whereas the fuel ethanol option is preferred in terms of resource conservation (since it is assumed to replace oil not coal), and also scores better in terms of human and eco-toxicity if assumed to replace lead-bearing oxygenates. ...
