Optimization study of OTEC delivery systems based on chemical-energy carriers. Final report
The techno-economic feasibility of chemical energy carriers was studied. Specifically, the chemical energy carriers analyzed were hydrogen, as a gas and as a liquid, and liquid ammonia. Designs of systems for producing and transporting chemical energy to shore were completed. Estimates of the cost at which chemical energy would be available from an onshore terminal have been prepared; these estimates are expressed as a function of two major variables-the shaft-power cost on board the OTEC plant and the distance of the OTEC plant from shore. The size and weight characteristics of chemical energy plants that could be placed on board an OTEC plant were estimated. A techno-economic evaluation of the marine riser connecting the OTEC platform with an ocean-bed platform was provided. A technical and economic evaluation of conversion of delivered ammonia to ammonium nitrate and urea was completed and a general analysis of chemical energy reconverted into electricity onshore was also made. The information for the major project tasks--production, transmission, terminaling, and conversion back to electricity--is given.
