The world is moving closer to mining the deep sea to accommodate surging demand for battery metals needed in the global energy transition, but opposition to the practice is also mounting. After years of review, the International Seabed Authority, or ISA, is nearing completion of regulations that would allow entities to begin collecting lumps of metal from the deep ocean. While some tout the process as a greener alternative to terrestrial mining, several ocean scientists and environmental groups are urging caution. This episode features interviews with: Douglas McCauley, a professor of ocean science at the University of California, Santa Barbara; Matthew Gianni, co-founder of the Deep Sea Conservation Coalition; DeepGreen Metals Inc. CEO Gerard Barron; and Jeffrey Drazen, a professor at the University of Hawai'i at Manoa. Energy Evolution co-hosts Dan Testa, Allison Good and Taylor Kuykendall are veteran journalists with broad expertise covering the utility, oil and gas and mining sectors.
