Available in PDF, EPUB and Kindle. Book excerpt: Economic, efficient and reliable thermal storage systems are a key need of solar thermal power plants in order to smooth out insolation changes, to permit operation during the night period and to provide an output management tool for shifting output production to periods with high revenues. Nevertheless, thermal storage development has become almost a stepchild within the international solar thermal programs. This is due to the fact, that thermal storage is less a technological problem - technologically sophisticated storage concepts have been tested successfully in the past - but a problem of system optimization and cost minimization. The very limited storage research conducted for solar thermal power 0 plants concentrated mostly on high temperature storage, starting at 400 C and 0 reaching beyond 1000 C, as required by central tower technology. On the lower end of the temperature scale, a large variety of storage projects has been conducted for house 0 heating and house cooling at temperatures ranging from ambient to 100 C and for 0 0 concentrating collectors at temperatures between 180 C and 300 C. In the meantime, commercial solar thermal plant technology has made considerable technological progress since the last R&D project on solar thermal storage had ended in 1985: Since then, more than 300 MWe of solar plants with parabolic trough collectors were installed in California and their operating temperature was increased from the 0 0 former 300 C threshold to almost 400 C.

Book excerpt: The disparity between energy production and demand in many power plants has led to increased research on the long-term, large-scale storage of thermal energy in aquifers. Field experiments have been conducted in Switzerland, France, the United States, Japan, and the People's Republic of China to study various technical aspects of aquifer storage of both hot and cold water. Furthermore, feasibility studies now in progress include technical, economic, and environmental analyses, regional exploration to locate favorable storage sites, and evaluation and design of pilot plants. Several theoretical and modeling studies are also under way. Among the topics being studied using numerical models are fluid and heat flow, dispersion, land subsidence or uplift, the efficiency of different injection/withdrawal schemes, buoyancy tilting, numerical dispersion, the use of compensation wells to counter regional flow, steam injection, and storage in narrow glacial deposits of high permeability. Experiments to date illustrate the need for further research and development to ensure successful implementation of an aquifer storage system. Some of the areas identified for further research include shape and location of the hydrodynamic and thermal fronts, choice of appropriate aquifers, thermal dispersion, possibility of land subsidence or uplift, thermal pollution, water chemistry, wellbore plugging and heat exchange efficiency, and control of corrosion.

Download or read book Environmental Risk Assessment for Aquifer Thermal Energy Storage written by and published by . This book was released on 1993 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report has been prepared by Pacific Northwest Laboratory at the request of the International Energy Agency (IEA). The US Department of Energy represents the United States in the IEA for Annex IV, the IEA task for research and development in aquifer thermal energy storage (ATES). Installation and operation of an ATES system is necessarily intrusive to ground-water resources. Therefore, governmental authorities usually require an environmental risk assessment to be performed before permission to construct an ATES system is granted. Writing an accurate statement of risk presupposes a knowledge of aquifer and ground-water characteristics and that an engineering feasibility study has taken place. Effective and logical presentation of the results of the risk assessment can expedite the grant of approval. Introductory remarks should address questions regarding why the ATES project has been proposed, what it is expected to accomplish, and what the expected benefits are. Next, the system configuration, including the aquifer, ATES plant, and well field, should be described in terms of size and location, design components, and thermal and hydraulic capacity. The final element of system design, the predicted annual operating cycle, needs to be described in sufficient detail to allow the reviewer to appreciate the net hydraulic, thermal, and hydrochemical effects imposed on the aquifer. Risks may be environmental or legal. Only after a reviewer has been introduced to the proposed system's design, operation, and scale can risk issues can be identified and weighed against the benefits of the proposed ATES system.

Download or read book University of Minnesota Aquifer Thermal Energy Storage (ATES) Project Report on the Third Long-term Cycle written by and published by . This book was released on 1994 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: The University of Minnesota aquifer thermal energy storage (ATES) system has been operated as a field test facility (FTF) since 1982. The objectives were to design, construct, and operate the facility to study the feasibility of high-temperature ATES in a confined aquifer. Four short-term and two long-term cycles were previously conducted, which provided a greatly increased understanding of the efficiency and geochemical effects of high-temperature aquifer thermal energy storage. The third long-term cycle (LT3) was conducted to operate the ATES system in conjunction with a real heating load and to further study the geochemical impact that heated water storage had on the aquifer. For LT3, the source and storage wells were modified so that only the most permeable portion, the Ironton-Galesville part, of the Franconia-Ironton-Galesville aquifer was used for storage. This was expected to improve storage efficiency by reducing the surface area of the heated volume and simplify analysis of water chemistry results by reducing the number of aquifer-related variables which need to be considered. During LT3, a total volume of 63.2 x 103 m 3 of water was injected at a rate of 54.95 m3/hr into the storage well at a mean temperature of 104.7°C. Tie-in to the reheat system of the nearby Animal Sciences Veterinary Medicine (ASVM) building was completed after injection was completed. Approximately 66 percent (4.13 GWh) of the energy added to the aquifer was recovered. Approximately 15 percent (0.64 GWh) of the usable (10 building. Operations during heat recovery with the ASVM building's reheat system were trouble-free. Integration into more of the ASVM (or other) building's mechanical systems would have resulted in significantly increasing the proportion of energy used during heat recovery.

Download or read book Renewable Energy in District Heating and Cooling written by International Renewable Energy Agency (IRENA) and published by . This book was released on 2017-03-04 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: District heating and cooling (DHC) combined with renewable energy sources can help meet rising urban energy needs, improve efficiency, reduce emissions and improve local air quality. Although currently dominated by fossil fuels such as coal and gas, DHC systems can be upgraded, or new networks created, to use solid biofuel, solar and geothermal energy technologies. Depending on local conditions, renewable-based DHC brings a range of benefits, including increased energy security, improved health and reduced climate impact.To date, only a few countries have taken advantage of their renewable resource potential for DHC or created policies to promote further uptake. Sweden and Switzerland have started promoting renewable-based district heating,while Denmark - with ambitious decarbonisation policies -already uses high shares. Many cities and regions envisage a growing role for district in their energy plans; some are also looking increasingly at district cooling.As this REmap sector study from the International Renewable Energy Agency (IRENA) shows, renewables could feasibly supply more than one fifth of the energy needed for DHC worldwide. But to drive the transition, policy makers need to fully understand the costs, bene¿ts and actual potential for renewable-based DHC.
