The world is moving towards a new hydrogen infrastructure where green hydrogen is produced by eletrolysis. Electrolysis uses electricity to split water into oxygen and hydrogen. Existing electrolyzers use rare and expansive metals like platinum. This makes large scale production of green hydrogen expensive. Naco technologies create coatings and materials to replace these expensive metals. The coatings can also be used in hydrogen fuel cells that are used in cars, ships and tomorrow possibly also in aeroplanes.
