The finalized $1.3 billion loan comes through the DOE's Advanced Technology Vehicles Manufacturing Loan Program, which holds $40 billion in direct lending authority to support groundbreaking clean technologies. Initially announced in July 2024 with a conditional commitment of $1.2 billion, the loan amount was subsequently increased and finalized as part of efforts to expedite projects that contribute to climate change mitigation and energy transition. Here are some of the primary benefits:
-
Strengthening Domestic Supply Chains: ENTEK's facility will play a significant role in onshoring the U.S. lithium-ion battery supply chain, thereby reducing reliance on foreign suppliers and increasing national energy security. The separators produced will be compatible with all existing EV battery chemistries, including popular formulations like NMC, NCA, LMFP, and LFP, providing versatility across the industry.
-
Economic Boost to Indiana: The project is expected to create 763 construction jobs and 635 permanent operational roles, providing a significant economic boost to the region. ENTEK is partnering with local educational institutions and community organizations to prioritize hiring locally, including workers displaced from other manufacturing industries. The focus on local hiring will not only provide immediate employment opportunities but also contribute to long-term skill development in the region.
-
Compliance with Clean Energy Policies: The project also helps EV manufacturers in the U.S. comply with domestic content rules under the 30D Clean Vehicle Credit, a key element of the Inflation Reduction Act. This ensures that electric vehicles assembled with domestically produced components can qualify for tax credits, making them more affordable for consumers and spurring broader adoption.
Meeting Market Demand and Future Growth
The growth of the EV sector in North America is expected to be exponential, with an increasing need for high-quality battery components. The DOE has projected that the annual requirement for lithium-ion battery separators in the region will rise to as much as 10 billion square meters by the end of the decade. ENTEK's facility, with a production capacity of 1.72 billion square meters, will address a significant share of this demand, supporting roughly 1.9 million mid-size electric vehicles or 1.3 million electric SUVs.
Beyond just automotive applications, ENTEK's separators will also be used in lithium-ion batteries for energy storage systems, playing a role in renewable energy projects that aim to provide more reliable and sustainable power solutions across the country.
Economic and Environmental Implications
The local economy in Terre Haute, Indiana, stands to benefit substantially from this project, which will serve as a significant driver of economic development.
