water and hydrogen technologies
Hähn technically combines what is chemically and physically inseparable on our planet: the molecules H2O and H2.
Choose from our water treatment plants for a demand-adapted water management or browse through our technologies that further process the high-purity water - to the energy carrier of the future: hydrogen.
hähn water treatment and hähn hydrogen: well-respected across 4 continents
Hähn continuously achieves success in the water management of its customers with its smart water treatment systems. A demand-adapted water treatment, if necessary with water recycling or recovery of recyclable materials, is economically and ecologically a benefit for your company.
Founded in 2016, Hähn is also probably the most family-oriented company in the hydrogen game. Its focus has always been on developing smart hydrogen technologies, in addition to its day-to-day project business. Hähn's expertise gained in this way has earned it a secure place at the forefront between the big players in the hydrogen market.
It is this excellent expertise that has already given Hähn and its customers a competitive edge in recent years. The technologies from both of the company's divisions are in demand internationally from well-known customers.
The hähn company
The company was founded in 2016 and is a growing business ever since. The registered office is located in the beautiful Rhineland in the north of the German state Rhineland-Palatinate.
We realized small- and large-scale projects both nationally and internationally in the company's two main divisions: industrial water treatment and hydrogen technologies. Our reliability and expertise is confirmed by standing customers.
Rising costs, the scarcity of raw materials and environmental topics demand smart answers and innovative technologies for a strong economy and a future worth living. We meet these increasing requirements with our expertise and innovative spirit.
Economic viability and technical reliability are the basis of our products.
Our conviction that our solutions make a positive contribution to each individual customer, our economy, our climate and our society drive us in a special way.

Latest News
Hydrogen plant in Rhineland-Palatinate
April 2023
Heading for the future: A hydrogen plant in Rhineland-Palatinate is to be built in the northern part of the state.
hähn hydrogen has been selected as the supplier of the entire plant technology. In the first construction phase, 2MW PEM electrolysers including peripherals are planned.
The electrolysis plant ensures the independent supply of oxygen and hydrogen to local businesses and facilities. The plant thus ensures regional competitiveness, expands the region's value-added potential and strengthens the business location of northern Rhineland-Palatinate.
Three sites are currently on the shortlist. Final decisions are expected before the end of the year.
Interested companies or municipal institutions are requested to contact Hähn.
Methanolsynthesis plant
Juli 2023
As part of a cooperation with energy supply companies, a demo power-to-X plant based on the methanol synthesis process is currently under development.
The hydrogen required for this as well as the necessary water treatment and the methanol synthesis plant itself come from Hähn. The required carbon is provided in the form of CO2 by means of tank trucks.
The methanol produced is to be sold to supply ships and emergency power systems.
Water treatment design 100 MW electrolysis
July 2023
Within the scope of an engineering contract of an internationally operating plant manufacturer, the design of an ultrapure water plant for the supply of a 100 MW electrolysis including treatment of the recirculate was carried out.
The German end customer is one of the largest energy suppliers in Central Europe.
Recycables recovery from waste water
May 2023
As part of a process development for an American corporation, a finely particulate valuable material is recovered from process water with a high alkali content.
The several 100 m3/h of process water are reused by means of zero-waste discharge. The valuable material is subsequently sold.
hähn water treatment introduces new processes that are being tested for the first time worldwide.
New site for stack production
May 2023
At the new site of hähn in Vettelschoß, construction work will soon begin on the new production line for the manufacture of hydrogen systems.
The 1,800 square meters of production space will be joined by 600 square meters of offices and 350 square meters of laboratories. The measure will be carried out in three construction phases.
Purification of production wastewater
June 2023
Within the scope of an engineering order, the planning of a wastewater treatment plant with approx. 100 m3/h for the purification of highly contaminated chemical wastewater was carried out. The processes and design drawings were provided to the internationally active chemical company by hähn water treatment. The implementation was carried out by the customer's own workshop.
Compared to the previous process, considerable amounts of chemicals and energy could be saved. In addition, direct discharge of the wastewater into a neighboring watercourse became possible.
33 MW hydrogen-electrolysers
June 2022
On behalf of a consortium of investors, hähn hydrogen is investigating the installation of a 33MW hydrogen PEM electrolysis plant.
The site is the factory premises of a Belgian chemical group in Germany.
Energy recovery from waste water
January 2022
Hähn has received another order from one of our long-standing customers. As part of the water management of a large chemical plant of the company Kandelium, the wastewater temperature is to be lowered before discharge.
Update December 2022
hähn water treatment introduced a plate heat exchanger into the wastewater stream. In this way, the heat that would otherwise have been generated expensively using natural gas can be put to good use. Our solution saves several thousand tons of CO2. With a one-time investment the customer gains money in the mid double-digit million range every year.
