Green steel from toxic red mud

An economical process with green hydrogen can be used to extract CO2-free iron from the red mud generated in aluminium production

01-Feb-2024 - The production of aluminium generates around 180 million tonnes of toxic red mud every year. Scientists at the Max-Planck-Institut für Eisenforschung, a centre for iron research, have now shown how green steel can be produced from aluminium production waste in a relatively simple way. In an ...

Ammonia: efficient hydrogen carrier and green steel enabler

Max Planck materials scientists use ammonia for sustainable iron- and steelmaking

28-Apr-2023 - When it comes to sustainability and green steel, everybody talks about hydrogen. But current means of storing and transporting hydrogen request high pressures and low temperatures, which are both energetically and economically costly. Ammonia is known to be a good hydrogen carrier. Yan Ma and ...

Atomistic Insights into Electrocatalysis

28-Mar-2018 - Electrocatalysts are important for many industrial processes as they enhance the conversion of electrical energy into chemical energy and thus help to store excessive electrical energy generated by renewable energy resources. Hydrogen is expected to be crucial for the storage of chemical energy. ...
