A Method and Device for Secure, High-density Tritium Bonded with Carbon

Dept. of Energy

Idaho National Laboratory (INL) created a novel method and device for secure, high-density storage of tritium. The high-density tritium is bonded with carbon by irradiating an intercalated precursor into tritium bonded with carbon in a substrate.  Existing solutions to safely secure tritium result in a low-density tritium, minimizing tritium’s potential as a significant energy source. 


A method and device for producing secure, high-density tritium bonded with carbon.  A precursor is intercalated between carbon in the substrate, then irradiated until at least a portion of the precursor is transmutated into tritium and bonds with the carbon in the substrate.  This forms bonded tritium, tritium bonded with carbon, that produces electrons via beta decay.  The substrate can be highly-ordered pyrolytic graphite, carbon fibers, carbon nanotunes, buckministerfullerenes, or combinations thereof.  The precursor can be boron-10 or lithium-6.  The resulting bonded tritium can be used in a long-term power source (preferably between 10 and 20 years), capable of operating under extreme environments (e.g. deep ocean, vacuum of space, high altitude, etc.) and under extreme temperatures (preferably up to 300°F).
