Abstract
A method for supplying hydrogen gas for consumption in at least one downstream process, the method comprising: electrolysing water to provide hydrogen gas; compressing the hydrogen gas in a multistage compression system to provide compressed hydrogen gas; and feeding at least a portion of the compressed hydrogen gas to the downstream process(es); wherein the multistage compression system comprises at least one centrifugal compression stage; wherein the hydrogen gas is dosed with nitrogen gas upstream of the centrifugal compression stage(s); and wherein the nitrogen gas is present in the compressed hydrogen gas when fed to the downstream process(es).
Claims11
A method for supplying hydrogen gas for consumption in at least one downstream process, the method comprising:
- electrolysing water to provide hydrogen gas;
- compressing the hydrogen gas in a multistage compression system to provide compressed hydrogen gas;
- and
- feeding at least a portion of the compressed hydrogen gas to the downstream process(es);
- wherein the multistage compression system comprises at least one centrifugal compression stage;
- wherein the hydrogen gas is dosed with nitrogen gas upstream of the centrifugal compression stage(s);
- wherein after dosing, the resultant nitrogen-blended hydrogen gas has an apparent molecular weight in a range from about 2.05 to about 7;
- wherein the nitrogen gas is present in the compressed hydrogen gas when fed to the downstream process(es);
- and
- wherein the downstream process(es) consumes nitrogen.
