  • A Phyto Finish: Could Seaweed Be Mined for Critical Minerals?

    NREL scientists and researchers from the University of Alaska Fairbanks are studying seaweeds as potential sources of rare earth elements (REEs) through phytoremediation and biomining efforts near Bokan Mountain in Alaska. By analyzing how seaweed accumulates REEs and developing cost-effective extraction methods, they aim to create sustainable and efficient ways to recover these critical minerals. The collaboration between NREL and UAF could lead to the establishment of large-scale seaweed farms for REE production, offering a cleaner alternative to traditional mining practices. This research has the potential to not only meet the growing demand for REEs but also contribute to bioremediation efforts and reduce the environmental impact of mineral extraction.

  • A Road Less Deadly

    An ambitious effort to reroute traffic around Alaska's Kenai Peninsula is underway to reduce moose-vehicle collisions and protect wildlife, including the implementation of wildlife crossings to guide animals safely across the road. The Sterling Highway near Cooper Landing is being redesigned with wider shoulders, passing lanes, and updated guardrails to enhance driver safety, while also alleviating congestion and improving the driver experience. The project plan includes innovative wildlife crossings, such as Alaska's first vegetated wildlife overpass, to promote safe passage for animals and prevent genetic isolation among animal populations. The construction, led by the DOT&PF and Federal Highway Administration, is now expected to cost over $955 million and involve the Kenaitze Indian Tribe in setting excavation standards and ensuring cultural observers are present during construction, with completion scheduled for 2031 and a five-year post-construction study to monitor wildlife use, crash reduction, and vegetation recovery.
