Seaweed explored as a potential source for green-energy minerals

Exploring the seas for sustainability, U.S. scientists are testing seaweed as a possible miner of key minerals needed for green energy.

Moira Donovan reports for Hakai Magazine.

In short:

• U.S. researchers, backed by ARPA-E, are investing in projects to determine if seaweeds can efficiently extract and concentrate valuable minerals like platinum and rhodium.
• Experiments have indicated that seaweeds might also be processed into biofuel components and phosphorus-rich mineral extracts.
• Marine biologist Susete Pintéus highlights that while seaweed mining won't replace traditional methods, it can augment the supply of essential minerals.

"It’s worth exploring other possibilities that align more with our ideas of a greener world—or a bluer world."

Why this matters:

Harnessing seaweed for mineral extraction could lead to less environmentally invasive mining methods, offering a dual benefit of protecting marine ecosystems while sourcing critical materials for technology and energy solutions.

In push to mine for minerals, clean energy advocates ask what going green really means.
