Title: Feasibility study of carbonaceous fuels synthesis on-board an OTEC platfrom. Project 8980 second topical report, July 1976--March 1977

Abstract

A techno-economic analysis of the feasibility of producing certain carbonaceous fuels onboard an OTEC platform is presented. This analysis was performed as part of a broader study of alternate chemical energy carriers that would be used to transport OTEC-produced energy to shore. Carbonaceous fuels considered were methanol, gasoline, and methane. The reaction of OTEC-produced electrolytic hydrogen and carbon dioxide obtained from either seawater or onshore sources under different process conditions forms methane or methanol. Gasoline is produced by the dehydrations of methanol. Preferred production processes for the synthesis of carbonaceous fuels are identified. Transportation and terminal facilities for delivering and receiving the offshore-produced energy carrier were assessed. Underwater pipelines and oceangoing barges were analyzed as methods for delivering carbonaceous fuels to shore. Although receiving facilities for pipelines were not included, oceangoing barge receiving facilities were considered; these consisted of storage tanks, unloading systems, and port facilities. As part of the product transmission system analysis, the delivery of carbon dioxide as a feedstock in both liquid and gaseous forms from onshore sources were analyzed. The analysis included transport by oceangoing barge and underwater pipeline. The unit costs of delivered energy from OTEC plants in the form of carbonaceous fuels ($10 tomore » $42/million Btu) are high. Improvements would be required to obtain OTEC shaftpower costs of near 10 mills/kWhr. The integration of advanced technology fuel production equipment along with low carbon dioxide costs are also required to obtain the low end costs of OTEC-derived carbonaceous fuels.« less
