Abstract:

This paper summarizes recent research accomplishments of the program and provides a synopsis of planned activities leading to a Net Power-Producing Experiment (NPPE), to be conducted at the Seacoast Test Facility (STF), at Keahole Point, Hawaii. The objectives and results of seawater testing performed at the DOE's STF/Heat and Mass Transfer Scoping Test Apparatus (HMTSTA) are summarized. These research efforts at the HMTSTA have provided the most recent and, in some cases, the only accurate seawater test results on the performance of flash evaporators, mist eliminators, and direct-contact condensers. The experimental results on these OC-OTEC subsystems have been compared to freshwater results, as well as predicted results. In addition to the above, the HMTSTA has been utilized to provide experimental data on the performance of surface condensers in seawater at OC-OTEC conditions. The quality of desalinated water, produced as a by-product of the OC-OTEC process, is discussed.
