US DoE Funds $100 Million in Non-Lithium Battery Projects

The US Department of Energy (DoE) has announced $100 million in funding for non-lithium battery projects. This initiative aims to support pilot-scale energy storage demonstration projects that focus on long-term energy storage using non-lithium technology. The funding will be provided through the agency’s Office of Clean Energy Demonstrations (OCED).

Funding Details

The DoE plans to support 3-15 projects with grants ranging from $5 million to $20 million each. These grants must be matched with private investment. The funding will aid in technology maturation activities, including design for manufacturability, pilot system development, fabrication and installation, operational testing and validation, and commercial scale system design and supply chain growth.

Importance of Non-Lithium Batteries

Non-lithium batteries, such as sodium-ion batteries, are crucial for diversifying the energy storage landscape. They allow developers and utilities to store excess renewable power generated from sources like solar and wind for use during off-peak hours. This flexibility is essential for managing the variable output of renewable energy sources.

America’s Energy Storage Needs

The DoE estimates that America will need an additional 700-900 GW of energy storage capacity to reach its 2050 net zero target. This massive scale-up will require a range of energy storage solutions, including both lithium-based and non-lithium-based technologies.

Support for Innovation

The DoE’s funding initiative aims to foster innovation in the energy storage sector. By supporting non-lithium battery projects, the DoE hopes to encourage the development of diverse and sustainable energy storage solutions. The agency’s commitment to funding a variety of projects underscores the importance of having multiple energy storage options available to meet future energy demands.


The US Department of Energy’s $100 million funding announcement for non-lithium batteries marks a significant step towards enhancing the country’s energy storage capabilities. By investing in a range of technologies, the DoE is helping to ensure a robust and flexible energy storage infrastructure. This initiative not only supports the advancement of non-lithium batteries but also contributes to achieving America’s long-term renewable energy goals.
