WASHINGTON, D.C. – Yesterday, Congressman John Joyce, M.D. (PA-13), Chairman of the Subcommittee on Oversight and Investigations, and Congressman Gary Palmer (AL-06), Chairman of the Subcommittee on Environment, sent a letter to Gene Dodaro, the Comptroller General of the Government Accountability Office (GAO), requesting an assessment of available or emerging technologies and materials that could be used to supplement critical minerals in semiconductors.

“Critical minerals such as lithium, cobalt, and rare earth elements are essential for technologies used in many sectors of the economy, including energy, transportation, national defense, health care, and consumer electronics,” said Chairmen Joyce and Palmer. “These minerals are vulnerable to supply-chain disruptions for several reasons, including U.S. reliance on foreign sources, as well as the rapid growth in demand for critical minerals in the U.S. and abroad.”

The letter asks the GAO to examine:

1. The status of domestic technologies and supplemental materials, such as critical minerals found in mine waste, tailings, or reclaimed from end-of-life batteries and electronic waste, that can serve as substitutes for foreign-sourced critical minerals from non-allied nations needed for semiconductors and energy grid or power electronics, including impacts on material and product performance.
2. Key technological challenges to the development or adoption of these domestic supplemental and materials to advance the diversification of U.S. critical mineral sources.

BACKGROUND:

In May, the Subcommittee on Oversight and Investigations held a hearing on ways to enhance our critical mineral supply chains. Energy and Commerce Committee Republicans are committed to strengthening our critical mineral supply chains and finding solutions to reduce our reliance on foreign sources, particularly when it comes to foreign adversaries like China. The Trump Administration has also worked hard to bolster these supply chains. Critical minerals are essential to American technologies and industries, and finding innovative domestic solutions that can contribute to our independence from non-allied nations is essential as we work to onshore American innovation and strengthen our national security.
