Age of hydrogen

The key for sustain­ability with renew­able ener­gies.

Climate change and limi­ta­tion of fossil energy sources require re-​eval­u­a­tion of our energy supply. Hydrogen emerges as a leading option for a sustain­able energy supply for mobility, trans­port, and indus­trial produc­tion. Renew­able energy alone cannot fulfil all demands without effec­tive energy conver­sion and storage solu­tions; thus, hydrogen is essen­tial for a reli­able energy supply.

The role of hydrogen as a clean replace­ment for fossil fuels depends on the produc­tion by elec­trol­ysis of water using power from renew­ables like hydropower, wind, or solar energy.

H2 pioneer since 1997

Fumatech is member of the BWT group.

Utilizing the syner­gies between BWT‘s lead­er­ship in water treat­ment tech­nolo­gies and Fumatech‘s cutting-​​​edge membrane tech­nology, we make signif­i­cant contri­bu­tions to the following areas in the hydrogen cycle:

• BWT: Water treat­ment and purifi­ca­tion for elec­trolyzers
• Fumatech: Highly stable ion exchange membranes for elec­trolyzers
• Fumatech: Energy effi­cient membranes for fuel cells
• Fumatech: Bipolar and monopolar membranes for CCU, Carbon Capture and Power-​​​to-X

Research and invest­ment since more than 25 years into the membrane tech­nology for hydrogen produc­tion and energy storage tech­nolo­gies.

Inno­v­a­tive membrane tech­nology by Fumatech BWT

The membrane makes the differ­ence.

Fumatech BWT has compre­hen­sive knowl­edge in all aspects of membranes‘ produc­tions. The company pursues two impor­tant elec­tro­chem­ical appli­ca­tion fields: water treat­ment and energy-​related appli­ca­tions.

• Membranes for Polymer elec­trolyte membranes for elec­trol­ysis and fuel cells appli­ca­tion are based on PFSA polymer.
• Membranes are typi­cally produced in rein­forced version in order to elim­i­nate swelling for large cells.
• Membrane’s prop­er­ties such as thick­ness and equiv­a­lent weight can be adjusted upon request.
• Membranes for alka­line water elec­trol­ysis are tailored for either circuit with concen­trated KOH or for KOH-​free circuit. The membranes are avail­able in customized width up to 150 cm and customized length up to 300 m.

Not all water is appro­priate for hydrogen produc­tion

Depending on the source of the water, it can contain numerous chem­ical and biolog­ical impu­ri­ties. For hydrogen produc­tion, water in its purest form is required. Munic­ipal water or water from any natural source cannot be used directly.

Water treat­ment plants are key compo­nent to achieve the neces­sary purity in the water. Following the motto „every­thing from a single source” BWT could offer inno­v­a­tive and envi­ron­men­tally friendly water treat­ment systems for hydrogen produc­tion.

There are various processes for producing hydrogen. Some use hydro­car­bons, others biomass, but the most envi­ron­men­tally friendly process is elec­trol­ysis of water using renew­able, clean energy. Raw water in its natural form is not an appro­priate source for producing green hydrogen. It must be pre-​treated for removal of suspended solids, iron, manganese, and other cont­a­m­i­nants, desali­nated to be free of minerals and finally puri­fied to pure and ultra­pure water quality. All indi­vidual treat­ment processes and unit oper­a­tions will be managed by a single control system.
