Recycling as the key for developing sustainable hydrogen storage materials — •Claudio Pistidda1, Yuanyuan Shang1, Thi Thu Le1, Gokhan Gizer1, Hujun Cao1, Nils Bergemann1, Rifan Hardian1, Martin Dornheim1, and Thomas Klassen1, 2 — 1Department of Materials Design, Institute of Hydrogen Technology, Helmholtz-Zentrum hereon GmbH, 21502, Geesthacht, Germany — 2Helmut Schmidt University, Holstenhofweg 85, 22043, Hamburg, Germany
Metals play a crucial role in supporting the global economy and the wellbeing of humankind. Supported by the constantly increasing demand for metal-based products, the extraction of mineral resources has increased, over the last decades, at a faster rate than economic growth. This trend is forecasted to steadily increase in the near future, thus leading to concerns over the exploitation of the Earth*s natural resources and the environmental impact that the extraction of metals will have. In this scenario, finding new ways to recycle metals and metal alloys, even those of low purity, is mandatory.
To reduce the carbon footprint and environmental impact that the mining of metals for hydrogen storage purposes entails and to reduce their cost, at the Helmholtz-Zentrum Hereon we pursue the possibility of obtaining high-quality hydride-based materials from industrial metal waste. A complete overview of recent scientific breakthroughs in the synthesis and characterization of hydrogen storage materials made from recovered metal wastes will be presented.
