ABSTRACT OF THE DISCLOSURE A method and apparatus is provided for operating a hydrogen engine with cryogenically stored hydrogen, wherein a pump, cooled down to an operating temperature close to the hydrogen boiling point, feeds hydrogen to the fuel-injection hydrogen engine. In order to improve the method and the apparatus so that the pump need not be maintained constantly at the operating temperature, it is proposed that the pump, when its temperature exceeds its operating temperature level, be purged with cold hydrogen gas and thus cooled down until its temperature drops to the operating level, and that the hydrogen gas that has been passed through the pump be utilized to propel the hydrogen engine at a partial-load range.
