Age of hydrogen

Hydrogen can store energy generated from renewable sources and make it available for later use.

Climate change and limi­ta­tion of fossil energy sources require re-​eval­u­a­tion of our energy supply. Hydrogen produced by water elec­trol­ysis using renew­able elec­tricity can be used as an energy carrier in selected mobility and indus­trial appli­ca­tions. In energy systems with fluc­tu­ating renew­able gener­a­tion, hydrogen can serve as one option for energy conver­sion and storage.

When hydrogen is produced by water elec­trol­ysis using renew­able elec­tricity, no fossil feed­stock is used in the elec­trol­ysis step. The overall envi­ron­mental impact depends on the elec­tricity source, plant config­u­ra­tion and full value chain.

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 offers water-treatment systems configured for the required feed-water quality, electrolyzer technology and plant capacity.

There are various processes for producing hydrogen. Water electrolysis can produce renewable hydrogen when the electricity used meets the applicable criteria for renewable electricity. Its environmental performance depends on the electricity source, water supply and plant configuration. Hydrogen produced using renewable electricity is being developed as an energy carrier for selected industrial, storage and mobility applications. 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.
