Oklo announces plans to collaborate with Vertiv and Liberty
In back-to-back press releases, Oklo recently announced two new partnerships that seek to advance the deployment of its commercial power reactors in the data center market.
These partnerships, one with Ohio-based Vertiv Holdings and one with Colorado-based Liberty Energy, continue Oklo’s trend in working to position their Aurora powerhouse as a key part of the energy solution for powering the AI boom.

By incorporating carbon nanotubes (CNTs) and graphene nanomaterials with aromatic sp2 carbon structures, we have specifically tuned filled ethylene propylene diene monomer elastomer (EPDM) seal and gasket composite materials for radiation resistance. Our results show that CNTs and graphene have an increased ability to stabilize the EPDM matrix compared to standard carbon black (CB) as a radiation-resistant filler. Graphene outperforms both CNT and CB fillers when considering surface damage under conditions where beta exposure is an issue. Both graphene and CNT fillers offer significantly reduced changes in glass transition temperature under prolonged exposure to tritium compared to CB-filled standards, with a 2.5-fold and almost 5-fold reduction, respectively. Thus, CNT- and graphene-filled O-ring materials could be designed that would maintain acceptable seals significantly longer than currently used composites.
