“As the world shifts from fossil fuels, additional sources of energy-on-demand will be needed to make up for lulls in wind or solar. A new way of extracting uranium from seawater could help even countries without uranium mines harness nuclear power in the post-carbon energy future. Trace amounts of uranium exist in seawater, but efforts to extract that critical ingredient for nuclear power have produced insufficient quantities to make it a viable source for those countries that lack uranium mines. A practical method for extracting that uranium, which produces higher quantities in less time, could help make nuclear power a viable part of the quest for a carbon-free energy future.”
