Ocean thermal energy conversion programmatic environmental analysis

Technical Report ·
OSTI ID:6325591

OTEC technology is reviewed and the existing environment of potential sites is described. The geology, oceanography, and economic profiles of these oceanic, subtropical-tropical regions are studied. The atmospheric effects of releases, particularly carbon dioxide, and sea-surface cooling, and associated climatic effects are projected. Land effects of the construction of plants and transmission cable entry points, and the marine ecosystem impacts caused by the attraction of organisms to the platform, intake and discharge of seawater and discharge of biocides are discussed. The health and safety hazards associated with OTEC, particularly regarding releases of Freon or ammonia, are assessed. Legal and regulatory aspects are discussed. Alternatives considered include the choice of power cycle (open or closed), platform configuration (land-based, moored, or plant-ship), seawater discharge design (separate or mixed releases) and intended power use (baseload electricity or at-sea production of ammonia or aluminum). 331 references.
