World’s first commercial-scale ocean thermal energy generator to be built off the coast of São Tomé and Príncipe
Ocean thermal energy conversion just crossed a threshold that has eluded engineers for nearly 140 years. UK-based Global OTEC Resources received independent certification for the cold-water riser pipe at the heart of its floating platform — the very component that has sunk previous attempts to turn ocean temperature gradients into electricity. The flagship vessel, Dominique, is a 1.5-MW system planned for deployment off São Tomé and Príncipe, an island nation of about 220,000 people that currently leans on imported fossil fuels. Because deep ocean temperatures stay constant, a working OTEC plant generates power around the clock, offering tropical island communities something solar and wind cannot: steady, locally produced baseload clean energy on the front lines of climate change.
