  "textContent": "A hydrogen fuel system for a work machine is disclosed. The hydrogen fuel system comprises a hydrogen storage tank containing hydrogen, the hydrogen being at least one of a liquid hydrogen or a gaseous hydrogen; a hydrogen power unit configured to consume the hydrogen from the hydrogen storage tank, the hydrogen power unit including at least one of a plurality of fuel cells or a hydrogen combustion engine; a boil-off pressure relief valve in fluid communication with the hydrogen storage tank; and a tank pressure sensor in communication with the boil-off pressure relief valve. The boil-off pressure relief valve is configured to, when the tank pressure sensor detects a pressure inside the hydrogen storage tank that exceeds a boil-off pressure threshold, vent the gaseous hydrogen to a boil-off fuel line fluidly connected to the hydrogen power unit.",
