Could the artificial introduction of oxygen revitalise dying coastal waters? While oxygenation approaches have already been proven successful in lakes, their potential side effects must be carefully analysed.

This is the conclusion of researchers from GEOMAR Helmholtz Centre for Ocean Research Kiel and Radboud University in the Netherlands .

They warn: Technical measures are no substitute for reducing nutrients and protecting the climate.

The expansion of plants for the production of green hydrogen is currently a topic of debate.

Green hydrogen is produced by electrolysis, which splits water into hydrogen and oxygen.

If the electrolysis are located near the sea, oxygen produced as a by-product could be used for oxygen enrichment measures in coastal marine regions.
