Energy Storage
Sealing Solutions for Energy Storage

As power generation increases to meet growing global demands, energy storage systems become crucial. Consider, for example, solar cells that produce electricity during the day to recharge electric vehicles at night. A smart grid requires high-performance energy storage options like redox flow batteries and lithium-ion battery storage to support such capability. As links and buffers, they balance fluctuating energy production against fluctuating consumption and establish a safe, reliable energy grid.
In addition to batteries, other innovative forms of energy storage and conversion are beginning to emerge and Freudenberg experts are ready to collaborate with customers on their development. Green hydrogen, for example, which is produced by electrolysis from the splitting of water by using electricity, is now building a bridge to E-Mobility. Fuel cells powered by hydrogen are already powering some municipal buses and long-haul trucks. And in the aviation industry, scientists and engineers are jointly researching the requirements needed to use green aircraft fuel.
