According to one or more aspects, systems and techniques for hydrogen fueling with integrity checks are provided herein. Communicated parameters measured by on-board sensors of a vehicle may be cross-referenced against calculated parameters measured by sensors of a fueling station. For example, communicated parameters relating to a compressed hydrogen storage system (CHSS) tank of a vehicle to be fueled may be received at different time intervals. Calculated parameters may be calculated based on a mass of hydrogen fuel dispensed by a hydrogen fueling station from a reference point to one of the time intervals and densities of the CHSS tank of the vehicle at respective time intervals. An error may be calculated between the communicated parameters and the calculated parameters. A fueling mode, such as a conservative fueling mode or a non-conservative fueling mode, may be determined based on the calculated error.
