Hydrogen storage materials from industrial waste

Recycled metal alloys allow circular economy for solid-state hydrogen storage


Not only the production of green hydrogen, but also its safe and compact storage is a major challenge for the energy transition. Metal hydrides could be a good solution - they can store large quantities of hydrogen in a small space. However, the mining and production of the up to now required ...

Perfluorinated Chemicals: Pollution is underestimated

Researchers discover overlooked contaminants in rivers


Per- and polyfluorinated chemicals (PFAS) can have harmful effects on human health and the environment. They are still used in numerous everyday products. Together with an international team of researchers, scientists at the Helmholtz-Zentrum Hereon investigated water samples from German and ...

Micrometer-sized particles encased in tailored polymer membranes

Hereon team unravels how metal hydrides can better store hydrogen


Metal hydrides are considered a cutting-edge storage material for hydrogen. These hydrides function even better, if the micrometer-sized hydride particles are coated with a thin polymer film. Using a sophisticated microscopy technique, a team at Helmholtz-Zentrum Hereon can now successfully show ...

First lockdown brought better air

The amount of nitrogen oxides fell by more than half in some cases due to the lockdown


Several studies have already shown: Concentrations of typical air pollutants such as nitrogen oxides and particulate matter have decreased worldwide during corona-related lockdowns. Scientists at the Helmholtz-Zentrum Hereon have now calculated in a comprehensive study for whole Central Europe ...

Microplastics: A Trojan Horse for Metals

Study shows that microplastics can serve as a transport vehicle for metals in the environment


The fact that microplastics can accumulate organic pollutants from the environment and transport them has been known for some time. What is new, however, is that metals can also be transported in this manner. In addition, the smaller the particles, the greater the metal accumulation on the ...

Better Understanding Membranes

A new class of membranes promises highly interesting applications in material separation, whether in biotechnology or water purification


The theoretical understanding of these polymer membranes is, however, still incomplete. Two researchers from Helmholtz-Zentrum Hereon and the University of Göttingen now present a study, published in the renowned science journal Chemical Reviews, that identifies these gaps in knowledge and shows ...
