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 ...

Slim steel - strong and safe

A material made from a few readily available components is very strong in tension and is nevertheless highly formable

31-Jan-2023 - Until now, developers of steels have had to make a choice: Either they increase the tensile strength of the material and usually accept that their material becomes relatively brittle. Or they rely on the fact that the steel can be strongly stretched and thus absorb a lot of energy in the event of ...

Special coating protects steel from hydrogen ‘attack’

Almost no evidence of brittleness

29-Jul-2020 - Regeneratively produced hydrogen is an ideal energy carrier, which will be used in future applications as fuel cells and cars and will supplement natural gas as an energy source. But atomic hydrogen often induces brittle behavior in metals at high temperatures. Lukas Gröner of the Fraunhofer IWM, ...

Deep decarbonization of industry is possible with innovations

27-Mar-2019 - On behalf of the EU Commission, Fraunhofer ISI explored what contribution individual technologies can make to decarbonizing industry and how to support them. The study shows that it is possible to cut emissions by 95% by 2050. However, this requires innovative carbon-neutral technologies and ...

Fibers from old tires can improve fire resistance of concrete

21-Feb-2019 - A new way of protecting concrete from fire damage using materials recycled from old tyres has been successfully tested by researchers at the University of Sheffield. The team used fibres extracted from the textile reinforcement commonly embedded into tyres to guarantee their performance. Adding ...

Rust never sleeps

Chinks in iron crystals that can 'heal'

06-Feb-2019 - Like iron flowing through the blood stream, iron minerals course through the ground. These minerals are used to make steel and other metal alloys used in everything from cell phone components and cars to buildings, industrial equipment and infrastructure. Unfortunately, when exposed to oxygen and ...

Yokogawa Joins Global 100 Most Sustainable Corporations in the World Index

23-Jan-2019 - Yokogawa Electric Corporation announces that it has been included in the 2019 Global 100 Most Sustainable Corporations in the World Index (Global 100). This is Yokogawa’s first time on the Global 100, one of the world's leading sustainability indices. Now in its 15th year, the 2019 Global 100 was ...

Developing new materials for the fusion reactor

Success in developing vanadium alloys strong at high temperatures

11-Dec-2018 - In the future fusion reactor, plasma is confined by using the magnetic field inside the doughnut-shaped vacuum vessel. The blanket is in a location where it almost touches the plasma, and as if to enfold the plasma the blanket is placed on the inner surface of the vacuum chamber. The blanket, by ...

Reinforcement of structures with Memory Steel

24-Oct-2018 - So far, the steel reinforcements in concrete structures are mostly prestressed hydraulically. This requires ducts for guiding the tension cables, anchors for force transfer and oil-filled hydraulic jacks. The space requirements of all these apparatuses created the geometric framework conditions ...

New solar tech can take the heat and pressure

New material, manufacturing process use sun's heat for cheaper renewable electricity

22-Oct-2018 - Solar power accounts for less than 2 percent of U.S. electricity but could make up more than that if the cost of electricity generation and energy storage for use on cloudy days and at nighttime were cheaper. A Purdue University-led team developed a new material and manufacturing process that ...
