Steel

The German steel giant is investing $1.9 billion in a hydrogen-powered direct-reduction system that can create high-quality steel without needing the rare, high-grade iron ore required by most green steel processes. This could open the floodgates.
-
As useful as steel is, its main weakness may be its vulnerability to corrosion. Researchers in Korea have now developed a new alloy coating that boosts steel’s resistance to rust, by adding a simple extra step in the surface treatment.
-
Scientists at Rice University have cooked up a new alloy with a unique and diverse set of attributes that could prove highly effective at protecting steel from corrosion, and can even heal itself when damaged.

Back In August we saw the world's very first "fossil-free" steel delivery makes its way to Volvo in Sweden, which the automaker has now fashioned into a mining lorry as a beacon of greener vehicle construction.
-
A milestone in decarbonization today as Sweden's SSAB made the world's very first "fossil-free" steel delivery, created with green hydrogen instead of coal and coke, to a customer, Volvo, where it will be used in electric trucks.
-
The world produces more than 1.8 billion tons of steel a year, releasing nearly twice that weight in carbon dioxide into the atmosphere. It's a huge decarbonization challenge, but steel giant ArcelorMittal is starting on a new green plant in Spain.
-
MX3D has finally realized its ambitious plan to install the world's first 3D-printed steel bridge over a canal in Amsterdam. The public bridge features integrated sensors to collect data on its structural integrity, crowd behavior, and more.
-
The steel industry is responsible for around 8 percent of all global carbon emissions annually, and decarbonizing it will require an enormous effort. H2GS plans to lead the way with the world's largest fossil-free steel plant, using green hydrogen.

Electric scooters typically consist of a tubular metal frame, covered with plastic body panels. Swedish startup Stilride is taking what it claims is a more eco-friendly approach with a scooter made from folded sheets of stainless steel.
-
Chromium is used to make tool steel or stainless steel, and it’s thought to have been invented around the late 19th and early 20th centuries. Archaeologists have now discovered that Persians were mixing chromium into steel way back in the 11th century.
-
Electronic waste can be difficult to repurpose, as it often consists of two or more mixed materials. Now, however, Australian scientists have developed a method of converting so-called e-waste into a protective coating for steel.
-
Whenever you try to improve steel, there are usually tradeoffs involved. It’s a balancing act between different properties. Now, engineers have developed a new type of “super steel” that defies this, staying strong while still resisting fractures.
