LLNL and Verne have demonstrated a novel pathway for creating high-density hydrogen through a research program funded by Department of Energy’s ARPA-E.  The demonstration validated that it is possible to efficiently reach cryo-compressed hydrogen conditions with liquid hydrogen-like density directly from a source of gaseous hydrogen.

Verne began working with LLNL in 2021 through a Strategic Partnership Project to test Verne’s tanks at LLNL’s cryogenic hydrogen fueling facility. Collaborations progressed through two Cooperative Research and Development Agreements in 2023-24 facilitated by LLNL’s Innovation and Partnerships Office (IPO).
