ABSTRACT
This entry examines the scope of availability of various by-products during power generation from ocean thermal energy conversion (OTEC) plants. Quantitative assessment of by-products such as potable water, mariculture/agricultural products, and different chemicals as may be made available for different types of OTEC plants, besides power saving from OTEC's application in cold storages, is made from the case study of a 100 MW OTEC plant. The revenue earning as determined per kWh power generation is observed to be quite lucrative. The prospect of hydrogen generation from the power available, and thereafter the scope of synthesizing ammonia and/or methanol (the mother chemical for synthesizing petrochemicals), is examined highlighting the advantages as well as the challenges to be resolved from R&D studies. The advantages and limitations in addressing global warming from the sequestering of CO2 are also examined, suggesting its optimal commercial application.
