Green hydrogen is regarded as a cornerstone of the global energy transition, and pure water is a vital input for its production. With a solution-oriented engineering approach, Herco offers customised water treatment solutions tailored to the specific demands of the hydrogen industry.

For almost eight decades, Herco has represented the strength of the German Mittelstand, evolving from a pioneering firm into a sustainable, future-oriented enterprise. As the first EMAS-certified water treatment company, Herco places a strong focus on environmentally responsible technologies, verified environmental management, and transparent documentation standards.

Through in-house production and customer-focused engineering, Herco develops reliable, innovative systems for demanding industrial applications. The company’s experience in sensitive sectors such as medical, pharmaceutical, and energy technology informs its precise and durable system design.

“Water quality is crucial for efficient electrolysis. Our systems deliver ultra-pure water – reliably, economically, and sustainably,” says Edwin Locker, Managing Director of Herco Wassertechnik GmbH. “At Hydrogen Expo, we will demonstrate how intelligent water treatment supports hydrogen production and makes it fit for the future.”
