Avalanche Energy Secures $5.2M DARPA Contract for Nuclear Battery Development
Avalanche Energy has received a $5.2 million contract from DARPA to advance technology for compact nuclear batteries, enhancing its fusion power initiatives. This project aims to develop micro-fabricated cells that convert radioisotope alpha particles into electricity, supporting defense and space applications.

Avalanche Energy has been awarded a $5.2 million contract from DARPA's Rads to Watts program to develop advanced nuclear battery technology over the next 30 months. The project targets the creation of solid-state, micro-fabricated cells capable of producing over 10 watts per kilogram using alpha particles from radioisotopes, enabling power for devices such as laptops for extended periods in harsh environments.
This initiative aligns with Avalanche's broader goal of commercializing portable fusion power by advancing energy conversion technologies applicable to fusion systems. The collaboration involves multiple institutions, including the University of Utah and Los Alamos National Laboratory, aiming to bolster capabilities in both defense and space sectors. Concurrently, Avalanche has secured $29 million in funding and a $1.25 million contract from AFWERX, indicating growing governmental and private support for its modular fusion technology.
