Historical achievement: underwater volcanoes used for electricity generation

Endurance Energy achieved a significant milestone in geothermal energy with the Adélie experiment at Axial Seamount, demonstrating the potential for ocean floor energy generation. The test involved harnessing hot water from hydrothermal vents, achieving temperatures of 281°C despite ocean pressure. The system produced a net positive energy output of 2 kilowatts, peaking at 16.5 kilowatts. However, operational challenges arose, leading to a temporary shutdown. Future plans include deploying improved equipment and a new drill capable of reaching depths of 500 meters to ensure sustainable energy production.
