Massive geothermal potential found offshore, where the Earth splits
A potentially game-changing and largely unexplored energy jackpot lies beneath the ocean floor, according to a whitepaper from geoscience tech consultancy CGG. Unique conditions under the sea bed promise cheaper and more accessible geothermal power.
So companies have tended to stick to areas they're relatively sure will deliver – like the Indo-Pacific "Ring of Fire," a tectonic belt that runs all the way up the West coast of the Americas, across to the Eastern tip of Russia, down through East Asia and across to cover New Zealand. On the other hand, there's a vast and much more consistent resource we could be targeting, says CGG, on the sea floor, right where the tectonic plates are constantly moving away from one another and generating new chunks of crust in a process called "seafloor spreading." In short, they replicate the best conditions you might find onshore in places like southern Iceland – where volcanic emissions have piled up on top of a seafloor spreading ridge to make it accessible from the land – except the offshore resources are much, much bigger.
