Negative Co2 Emissions

A deep-subsea OTEC concept is simulated, and a threefold increase in exergy efficiency can be achieved as to the topside one. On the environmental aspect, a deep-subsea OTEC concept can bring about negative CO2 emissions, which poses a positive environmental risk. On the economics, with appropriate public funding, a 100 MW deep-subsea OTEC asset would cost about USD2010 600 million. On the life-cost of energy, values between 40-60 USD2010/MWh are predicted.
