Crop residues as a fuel for power generation

Description: Crop residues could serve as an alternative energy source for producing electric power and heat in agricultural regions of the United States. Nearly 2 quads of residues are estimated to be available as a sustainable annual yield. These can substitute for up to one quad of conventional fuels used to generate electricity and up to an additional quad of petroleum and natural gas currently used for producing heat. The most promising routes to residue conversion appear to be regional generators size… more

Preliminary targeting of geothermal resources in Delaware. Progress report, July 15, 1978-July 14, 1979

Description: Results of temperature logging the five DOE 1000 foot test wells in Delaware indicate that the potential is good for a relatively low temperature geothermal resource (temperatures less than about 80/sup 0/C). A preliminary Bouguer gravity map was made for portions of Kent and Sussex counties in order to detect gravity anomalies possibly related to granitic plutons. The map indicates a gravity low trending northeast-southwest across Sussex County that could be indicative of other structural feat… more

Griffithsville unit tertiary recovery carbon dioxide pilot test, Lincoln County, West Virginia. Third and final annual report, August 28, 1977-August 28, 1978

Description: The three-year contract expired on August 28, 1978, without completion of the original intent of testing the effectiveness of carbon dioxide on effective enhanced oil recovery agent, owing to unforeseen problems of environment control, the dump flood and extreme weather condition. However, all of the preparations for carbon dioxide has been accomplished and the pilot is in excellent condition for proceeding with the program. Although cost overruns may be over $1,500,000, additional testing over… more

Conceptual flow sheets development for coal conversion plant coal handling-preparation and ash/slag removal operations

Description: This report presents 14 conceptual flow sheets and major equipment lists for coal handling and preparation operations that could be required for future, commercial coal conversion plants. These flow sheets are based on converting 50,000 tons per day of clean coal representative of the Pittsburgh and Kentucky No. 9 coal seams. Flow sheets were used by Union Carbide Corporation, Oak Ridge National Laboratory, in a survey of coal handling/preparation equipment requirements for future coal conversi… more

Silicon-on ceramic process. Silicon sheet growth and device development for the large-area silicon sheet and cell development tasks of the low-cost solar array project. Quarterly report No. 12, April 2, 1979-June 29, 1979

Description: The objective of this research program is to investigate the technical and economic feasibility of producing solar-cell-quality sheet silicon. We plan to do this by coating one surface of carbonized ceramic substrates with a thin layer of large-grain polycrystalline silicon from the melt. During the quarter, significant progress was demonstrated in several areas: (1) a 10-cm/sup 2/ cell having 9.9 percent conversion efficiency (AM1, AR) was fabricated; (2) the Honeywall-sponsored SCIM coating d… more

Liquid fuels production from biomass. Progress report No. 8, April 1-June 30, 1979

Description: The current program to convert biomass into liquid hydrocarbon fuels is an extension of the previous program to ferment marine algae to acetic acid. In that study, it was found that marine algae could be converted to higher aliphatic organic acids and that these acids could be readily removed from the fermentation both by membrane or liquid-liquid extraction. It was then proposed to convert these higher organic acids to aliphatic hydrocarbons via Kolbe Electrolysis, which may be used as a diese… more

OTEC cold water pipe hydroelastic response experiment

Description: OTEC cold water pipes in an ocean current cross-flow will experience time dependent hydrodynamic loads induced by alternate shedding of vortices. For flexible pipes the problem becomes increasingly complex since the hydrodynamics couples with the dynamics of the pipe producing a phenomenon known as vortex strumming. The general approach taken is to first identify the important parameters influencing the motion of typical OTEC cold water pipes in still water. The relevant parameters are identifi… more

Klamath County YMCA geothermal heating project environmental assessment

Description: The YMCA Geothermal Heating project proposes to obtain approximately 57% of the total facility energy usage through direct application of the Klamath Falls KGRA. This will be accomplished through the design and construction of a retrofit and injection system for the utilization of an existing 110/sup 0/F geothermal energy source at the project site. The existing 2016 foot well will be outfitted with a turbine pump with variable speed drive. The well head will be enclosed by a 10' x 10' building… more

Economics and siting of Fischer-Tropsch coal liquefaction

Description: The capital intensity and low conversion efficiency of Fischer-Tropsch synthesis makes it noncompetitive with conventional petroleum in the midterm (e.g., 5 to 10 years) under normal economic conditions. However, if crude oil prices rise to higher levels (e.g., $25 to $30/bbl), coal liquefaction processes may prove to be economical. It appears that several other processes under development may become economically attractive before Fischer-Tropsch, although Fischer-Tropsch is the only proven com… more
