“…The best current indication of the cost of direct injection is $90-180 tonne −1 CO 2 (Fujioka et al, 1997;Summerfield et al, 1993), further indication of how uneconomic cooling towers and air injection are for carbon sequestration. • If a discount rate of 6%, typical of the cost of borrowing for major public projects, is used instead of 10%, the cost of creating 1 m 3 of downwelling current by the formation of sea ice drops from $0.0004 m −3 to $0.0003 m −3 .…”

Downwelling ocean currents carry carbon into the deep ocean (the solubility pump), and play a role in controlling the level of atmospheric carbon. The formation of North Atlantic Deep Water (NADW) also releases heat to the atmosphere, which is a contributor to a mild climate in Europe. One possible response to the increase in anthropogenic carbon in the atmosphere and to the possible weakening of the NADW is modification of downwelling ocean currents, by an increase in carbon concentration or volume. This study assesses the costs of seven possible methods of modifying downwelling currents, including using existing industrial techniques for exchange of heat between water and air. Increasing carbon concentration in downwelling currents is not practical due to the high degree of saturation of high latitude surface water. Two of the methods for increasing the volume of downwelling currents were found to be impractical, and four were too expensive to warrant further consideration. Formation of thicker sea ice by pumping ocean water onto the surface of ice sheets is the least expensive of the methods identified for enhancing downwelling ocean currents. Modifying downwelling ocean currents is highly unlikely to ever be a competitive method of sequestering carbon in the deep ocean, but may find future application for climate modification.

“…A further concern is the logistics associated with the supply and servicing of the pipeline lay-barge so that standard operating schedules are maintained. 71 This would require the use of many other vessels such as supply boats, pipe carriers, survey vessels and so on. There is also a short operating season during which the pipeline could be laid, so it would take several years.…”

The design concept for a ‘clean energy producing vessel’ proposes the exploitation of remote offshore gas reserves, primarily from stranded fields, using a floating electrical power generation plant. In comparison to conventional approaches utilising liquefied natural gas and pipeline technologies, the clean energy producing vessel represents a highly innovative approach to the production and transportation logistics of natural gas for electricity generation. The main objective of this article is to undertake a financial evaluation of the clean energy producing vessel design concept. This is achieved by developing a financial model comprising cost and revenue modular elements that reflect the major technical components of the design concept: the floating production, storage and offloading unit; the electrical generation plant; cable transmission; carbon capture and electricity prices. The results for net present value and internal rate of return are derived for all combinations of either high- or low-revenue scenarios and for high- or low-cost scenarios. With a rather low internal rate of return of just 15.53%, the only scenario that yields a positive outcome is that of the high-revenue and low-cost combination. Accounting for savings in carbon dioxide emissions exerts only a negligible impact upon the results. Analysis of future research required concludes that following its deployment and implementation, the feasibility of the clean energy producing vessel design concept depends on the outcomes of economic and technological assessments, which are difficult to predict with any degree of certainty.

“…In this study, a range of different options were studied, such as CO 2 disposal options, options for power plants, and CO 2 separation process and disposal route options. Summerfield, Goldthorpe, Williams, and Sheikh (1993) showed that the cost of CO 2 disposal contributed to a large portion of the cost of a low-CO 2 generation system. The cost of CO 2 transport and removal ranged from around £18-£108 per ton (US $33-$203/ ton) of CO 2 emission avoided, depending on the type of power plant, and the CO 2 separation and disposal options.…”

The Arctic Energy Technology Development Laboratory was created by the University of Alaska Fairbanks in response to a congressionally mandated funding opportunity through the U.S. Department of Energy (DOE), specifically to encourage research partnerships between the university, the Alaskan energy industry, and the DOE. The enabling legislation permitted research in a broad variety of topics particularly of interest to Alaska, including providing more efficient and economical electrical power generation in rural villages, as well as research in coal, oil, and gas. The contract was managed as a cooperative research agreement, with active project monitoring and management from the DOE.In the eight years of this partnership, approximately 30 projects were funded and completed. These projects, which were selected using an industry panel of Alaskan energy industry engineers and managers, cover a wide range of topics, such as diesel engine efficiency, fuel cells, coal combustion, methane gas hydrates, heavy oil recovery, and water issues associated with ice road construction in the oil fields of the North Slope. Each project was managed as a separate DOE contract, and the final technical report for each completed project is included with this final report.The intent of this process was to address the energy research needs of Alaska and to develop research capability at the university. As such, the intent from the beginning of this process was to encourage development of partnerships and skills that would permit a transition to direct competitive funding opportunities managed from funding sources. This project has succeeded at both the individual project level and at the institutional development level, as many of the researchers at the university are currently submitting proposals to funding agencies, with some success.
