The southeast United States is emerging as a national hub for manufacturing batteries, components, and critical materials, positioning the country as a globally competitive player in the industry. With continued private and public sector support, this industry will bolster the energy, mobility, and defense sectors crucial to U.S. global economic competitiveness, grid reliability, and national security. To explore this opportunity, C2ES is convening key stakeholders across the southeast region to develop approaches to accelerate the expansion of the regional critical battery materials supply chain through fostering supportive state and federal policies, creative partnerships, entrepreneurship and innovation, and capital investment.
