E.ON + FuelCell Energy: Water treatment plant for fuel cell
Energy history is being written in Mannheim. The first European fuel cell in the megawatt power range is running there. The water treatment system was designed and manufactured by EnviroFALK.
This energy solution is a milestone for the green energy world of the future because, unlike conventional generation plants, it supplies heat and electricity with virtually no pollutants. The innovative plant was realized jointly by E.ON and FuelCell Energy Solutions at the company FRIATEC AG and ceremoniously put into operation.

Challenge for the customer
The reforming of hydrogen from methane (natural gas) requires high-purity water for the fuel cells.
In a DFC® fuel cell, hydrogen and oxygen react with each other in an efficient electrochemical process to generate electricity, heat and water with virtually no pollutant emissions. For the internal reforming of hydrogen from methane (natural gas), high-purity water must be added to the process in the fuel cell stack.
The water is treated using permeate-stage reverse osmosis as the main desalination process with upstream anti-scaling conditioning. The water is also subjected to fine desalination using membrane degassing to remove CO2 and continuous electrodeionization (CEDI). All process-relevant parameters of the system, such as flow rates, pressures and water qualities, are continuously measured online and transferred from the EnviroFALK automation system to the customer’s process control system. The water treatment is controlled by the customer via a round-the-clock system monitoring system.
Magnus Häbel: “What sets us apart at EnviroFALK? We are extremely good at adapting to special customer requirements. Thanks to our flexibility, our water treatment systems are optimally adapted to the areas of application and the conditions on site.”
