1. A liquid hydrogen production facility comprising:
a reformer configured to generate hydrogen gas by reforming a hydrocarbon, the reformer outputting the hydrogen gas to a hydrogen liquefier and carbon dioxide to a heat exchanger;
a reservoir;
the hydrogen liquefier, the hydrogen liquefier being configured to generate liquid hydrogen by liquefying the hydrogen gas received from the reformer, the hydrogen liquefier outputting the liquid hydrogen to the reservoir for storage; and
the heat exchanger, the heat exchanger being configured to receive boil-off gas from the liquid hydrogen in the reservoir and the carbon dioxide from the reformer and cause heat exchange between the boil-off gas and the carbon dioxide to liquefy the carbon dioxide.
