WEINHEIM, Germany—Freudenberg Sealing Technologies (FST) is providing seals for electrolyzers to meet expected high demand for hydrogen production based on solar and wind power.
The membrane electrolysis components are designed for mass-manufacture and automated assembly—even though some are up to one meter in diameter, FST said in a recent statement. The seals were developed in anticipation of a significant increase in the global production capacity for green hydrogen.
According to FST, the electrolysis technologies—to split water using green power—are well-advanced, with "membrane electrolysis" particularly suitable for intermittent production with a highly fluctuating power supply.
The German manufacturer said its solutions include molding the sealing material directly onto functional parts or applying the seal to specialized carriers, which are easier to transport and install.
