Our colleagues and advisors from US DOE provided a link to a quite interesting webinar on LH2 transfer at hydrogen filling stations.
On https://www.energy.gov/eere/fuelcells/downloads/thermodynamic-and-economic-modeling-boil-losses-liquid-hydrogen-handling you can listen to the recording or download the slides.
Interestingly there is a link to a publication and a MATLAB code of LLNL for simulating the transfer of LH2.
