"Transforming Aluminum Mining Waste into Climate-Friendly Green Steel"

Researchers in Germany have developed a method to extract iron and potentially other metals from the waste generated during aluminum production, known as red mud, using hydrogen and electricity sourced from renewable power. This process could potentially lead to the production of "green steel" with significantly lower carbon emissions. While the method reduces the environmental impact of the waste and neutralizes its pH, it is energy-intensive and economically challenging due to the cost of energy required. Nonetheless, the low carbon emissions make it a promising avenue for sustainable metal production.

"Transforming Waste into Green Steel: Innovative Methods for Sustainable Production"

Red mud, a by-product of aluminium production, is a major environmental issue due to its accumulation and disposal. A new study proposes using hydrogen plasma to directly extract iron from red mud, offering a sustainable and carbon-neutral method for steel production. The process involves exposing red mud to a lean hydrogen thermal plasma, resulting in the production of liquid iron without the need for prior treatment. This innovative approach not only extracts valuable iron but also renders the residual material into a neutral product suitable for other industries, addressing both the issue of red mud waste and the production of iron without direct CO2 emissions.

"Record-Breaking Funding Secured for World's First Green Hydrogen Steel Plant"

The world's first full-scale green steel plant is being developed in Sweden, with the help of green hydrogen, marking a significant step in decarbonizing the steel industry. Green hydrogen, produced from renewable energy sources, is being used to replace fossil fuels in the steelmaking process, significantly reducing CO2 emissions. H2 Green Steel, the company behind the initiative, has secured funding and aims to start production in 2025, with plans to expand its impact on decarbonizing hard-to-decarbonize industries. The use of green hydrogen in steel production is seen as a promising solution to address the industry's significant carbon footprint.

"Record-Breaking Financing Secured for World's First Green Hydrogen Steel Plant"

H2 Green Steel secures €4.5bn in additional funding for the world’s largest green-hydrogen-based steel project in northern Sweden, aiming to produce near-zero-emission steel by replacing coking coal with green hydrogen and using renewable energy. The project, with close to €6.5bn in financing, is set to take a final investment decision soon and has already begun construction, with production expected to start in 2027. The company has secured contracts with major customers and financing from a group of lenders, including the European Investment Bank, and has also raised equity and received grants from the EU’s Innovation Fund.

"British Steel's Closure Plan Threatens 2,000 Jobs and Polluting Blast Furnaces"

British Steel plans to close its blast furnaces in Scunthorpe, putting up to 2,000 jobs at risk. The company aims to replace them with two electric arc furnaces, one in Scunthorpe and one in Teesside, as part of a £1.25bn proposal to become a "clean, green and sustainable business." The plans are subject to government support. Unions estimate that the shift could lead to the loss of 1,500 to 2,000 jobs. The closure of the blast furnaces would leave the UK without the ability to produce "virgin steel," but the government argues that electric arc furnaces can cover most of the country's steel needs.

"British Steel's Furnace Closure Puts Thousands of Jobs at Risk"

British Steel plans to close its blast furnaces in Scunthorpe, putting up to 2,000 jobs at risk. The company aims to replace them with two electric arc furnaces to make the business more environmentally sustainable. The proposal is subject to government support, and if approved, the new furnaces could be operational by late 2025. Unions express concern over the migration timeline and the potential loss of jobs. The UK government is discussing a support package of around £300m to £500m to transition the steel industry to greener practices.

Revolutionizing Steel Production: The Electrowinning Solution for Green Steel

Steel manufacturers around the world are exploring ways to decarbonize the CO2-intensive steel industry, which generates as much as 9 percent of human-caused CO2 emissions annually. One approach is the use of electric arc furnaces powered by renewable energy sources, which can reduce carbon emissions by up to 75 percent compared to traditional coal-based methods. However, to truly decarbonize the industry, a fundamental shift in primary steelmaking technology is needed, such as using hydrogen to process iron ore. Several projects involving hydrogen are in development worldwide, but significant investment in renewable energy capacity and next-generation technologies will be required. Government policies, collaboration between steel suppliers and customers, and retraining of workers will also be crucial in achieving a sustainable and low-carbon steel industry.

NATO Summit Excludes Ukraine's Invitation to Join Alliance, Stoltenberg Confirms

NATO chief Jens Stoltenberg said there are no ongoing discussions about Ukraine joining NATO in the upcoming July summit in Vilnius, Lithuania, but there will be active discussions on "how to move Ukraine closer to NATO." Meanwhile, Ukraine is seeking $40 billion in funding for the first phase of a "Green Marshall Plan" to repair its economy, which includes developing a coal-free iron and steel industry. The country is also seeking access to the estimated $300 billion of frozen Russian central bank reserves to help with its reconstruction.

Germany aims to fund Thyssenkrupp's green steel plant with $2.1 billion.

Germany plans to provide around €2bn ($2.1bn) to help fund Thyssenkrupp's green steel plant in Duisburg, one of the company's key turnaround projects. The funding commitment includes €700m from the German state of North Rhine-Westphalia. Thyssenkrupp depends on external funds to pay for decarbonising steelmaking, which is one of the most polluting industrial production techniques. The company plans to commission a direct reduction iron plant for the climate-friendly production of 2.5 million tonnes of steel annually, with a production start scheduled for 2026.
