There are different techniques for producing hydrogen. Depending on the process, the hydrogen obtained may be labelled as black, grey, blue, green, etc.... Currently, 95% of the hydrogen consumed worldwide is produced from natural gas or coal.... If steps are added to the production cycle to capture and store the emitted CO2, the resulting hydrogen will be labelled blue hydrogen. 1, record 1, English, - blue%20hydrogen

Il existe différentes techniques de production de l'hydrogène. Selon le procédé choisi, l'hydrogène obtenu pourra être qualifié de noir, gris, bleu, vert, etc. Actuellement, 95 % de l'hydrogène consommé à l'échelle mondiale est produit à partir de gaz naturel ou de charbon. [...] Si des étapes sont ajoutées au cycle de production pour capter et stocker le CO2 émis, l'hydrogène obtenu aura l'appellation d'hydrogène bleu. 1, record 1, French, - hydrog%C3%A8ne%20bleu

There are different techniques for producing hydrogen. Depending on the process, the hydrogen obtained may be labelled as black, grey, blue, green, etc.... Currently, 95% of the hydrogen consumed worldwide is produced from natural gas or coal.... Green hydrogen can be produced by "water electrolysis, "whereby an electric current is passed through water to break down its molecules... and extract hydrogen. In addition, if the current comes from a renewable energy source(hydroelectricity, wind or solar power), all elements of the generation cycle are low-carbon. 3, record 2, English, - green%20hydrogen
