Led by Professor Om Parkash Dhankher, the UMass Amherst research team has enhanced Camelina sativa to accumulate significant nickel levels from low-concentration soils. Unlike traditional phytomining techniques, which rely on slow-growing and invasive plants like Odontarrhena, this approach offers a faster and more efficient solution.
Key advantages of this plant-based nickel mining method include:
Currently, the U.S. relies heavily on Indonesia and other international sources for nickel supply. With just one active nickel mine in the country, domestic manufacturers—especially those in the electric vehicle (EV) and battery sectors—face supply chain vulnerabilities.
UMass Amherst researchers estimate that this phytomining technique could meet 20-30% of U.S. nickel demand by cultivating the crop on one million acres of underutilized land containing trace nickel deposits. This approach could significantly reduce reliance on imported nickel while enhancing U.S. mineral independence.
Recognizing the potential of this technology, the Department of Energy has awarded the research team $1.3 million to further develop the genetically modified Camelina strain. This funding highlights federal interest in sustainable mining alternatives and their role in securing domestic critical minerals for industries such as battery manufacturing and renewable energy.
Professor Baoshan Xing, another key researcher in the project, is leading efforts to optimize soil conditions for maximum nickel absorption. These advancements could create new opportunities for agricultural biotechnology companies, soil remediation specialists, and sustainable farming initiatives.
Beyond mineral extraction, this phytomining technology offers long-term environmental benefits. It can:
As industries look for cleaner alternatives to traditional nickel mining, the UMass Amherst phytomining breakthrough could become an asset in critical mineral production.
