Vodíkovou

Vodíkovou is a Czech feminine singular inflected form of the adjective vodíkový, which is derived from vodík (hydrogen). It is used to describe nouns that pertain to or involve hydrogen and appears primarily in technical, scientific, and energy-related language. The base form vodíkový denotes hydrogen-related properties, and when the adjective modifies feminine nouns in certain grammatical cases, it changes to vodíkovou.

In Czech, vodíkovou can function in the instrumental singular and the accusative singular of feminine nouns. This makes it common in formulations such as vodíkovou energií (by hydrogen energy, instrumental) or vodíkovou metodou (by hydrogen method, instrumental). The corresponding nominative feminine form is vodíková (for example, vodíková energie – hydrogen energy).

The term itself does not have an independent meaning beyond its role as a grammatical form of the hydrogen-related adjective. It is used wherever a feminine noun must be described as hydrogen-related, including discussions of hydrogen fuel, hydrogen production, or hydrogen-based technologies.
