A system includes a gas monitor including a gas sensing element, a wireless communication interface, and a sensor calibration including an operability calibration. The system also includes a gas station comprising at least one gas monitor physical interface and a wireless communication interface and a data manager comprising a wireless communication interface and an external communication interface, and configured to implement external communications between a remote device and the gas monitor, and between the remote device and the gas station. At least one of the gas station or the data manager is configured to update the sensor calibration to a monitoring calibration.

Aspects of the disclosure are directed to an optimization model for storing liquid hydrogen to power fuel cells in data centers. The optimization model can be based on hydrogen fuel consumption rates in the data center, refueling rates from vendors, refueling response time, storage tank area constraints in the data center, and/or logistical refueling constraints. The optimization model can allow for providing sufficient fuel within a constrained space for backup power in the data center, such as when an emergency arises.
