Water electrolysis was discovered about 230 years ago, but it took one century until technical application
became feasible. Starting from the late 1800s, electrolysers based on the liquid alkaline technology reached maturity and commenced a decade-long success story, reliably providing hydrogen at scale for industrial application.

However, throughout the 20th century, fossil fuel based hydrogen production methods became predominant and displaced water electrolysis into niches, especially at hydroelectric sites.

In recent decades, electrolysers appeared back on stage, driven by the advent of low-cost renewables
together with surging decarbonization policies, and not least by the development and ongoing advancement of the PEM technology for water electrolysis, Hydrogen Contango has achieved unique technical break-through in the field, and we keep developing innovative solutions to accelerate a sustainable comeback of electrolysers at real economic competitiveness, Our goal is no less than the broad and finite cost- & quality revolution of PEM electrolysers, to make carbon-free hydrogen production great again, greater than ever before.
