Indicator additives for a safe hydrogen economy
In the future, so-called green hydrogen produced with renewable energy is to become the key building block for a more sustainable and climate-friendly energy economy. For the realization of a hydrogen economy, the safety aspect in particular represents a major challenge. Hydrogen gas, which is to be used almost everywhere as a flexible energy carrier, cannot be perceived with human senses. However, it is highly flammable and explosive in air, as historical events (fire of the zeppelin "Hindenburg" in 1937) prove.
In order to increase safety within the complex hydrogen infrastructure, researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have researched the basic functional mechanisms for a novel hydrogen sensor, based on a concept developed at the Fraunhofer Institute for Silicate Research ISC in Würzburg.
