Tenova, DMV to recover flared hydrogen in pipemaking
Tenova has established a consortium with DMV, along with other companies, to execute a project aimed at reducing the carbon footprint of the bright annealing process in stainless steel seamless and nickel alloy tube production.
DMV was previously known as Mannesmann Stainless Tubes and is now part of Cogne.
The so-called LIFE H2Reuse project, funded by the EU, focuses on decarbonisation via the recovery and reuse of hydrogen. Tenova initiated the project this summer, aiming to improve energy efficiency while also enhancing the efficiency of hydrogen burners, optimising resource utilisation, and decreasing operating expenses.
“This groundbreaking initiative seeks to develop innovative solutions for hydrogen recovery and reuse … In the bright annealing process, 100% hydrogen is used in high-temperature furnaces to produce high-performance tubes with superior surface quality, corrosion resistance, and durability,” Tenova says in note sent to Kallanish.
“Currently, hydrogen is flared after each production cycle, leading to significant waste. The Life H2Reuse project aims to address this issue by developing two innovative technical solutions: recovering the wasted hydrogen from the annealing process and reusing it as fuel in radiant tubes working 100% of hydrogen. This approach represents a market-first innovation, as the recovery of atmospheric gas for reuse in industrial processes is not yet commercially available,” the technology supplier adds.
Tenova will test the project on its roller hearth furnace plants to reduce their carbon footprint.
In July, pipemaker Tenaris started decarbonising its steelmaking process using hydrogen and launched a trial at its Dalmine mill in Bergamo, Italy. This was the result of a six-month partnership with Snam and Tenova. The company’s objective is to use on-site hydrogen production to power a newly developed burner by Tenova, which is fully compatible with 100% hydrogen.

Tata Steel signs contract for new EAF at Port Talbot site
The new EAF, expected to become operational at the end of 2027, will have a capacity for 3 million tonnes per year of steel.
By transitioning to the new EAF technology, the Port Talbot site will be able to produce green steel, Tata Steel said. It will reduce its carbon emissions by 90%, which is equivalent to 5 million tonnes of CO2 per year, the company added.
According to the company, the use of scrap in the new EAF will also reduce the UK’s reliance on imported iron ore.
The new EAF will be funded by a joint investment of Tata Steel and the UK government reaching £1.25 billion ($1.62 billion). Tata Steel will provide £750 million of the whole sum, and the investment of the UK government will be up to £500 million.
The grant from the UK government was approved on September 11.
The new EAF is supposed to replace the two blast furnaces (BFs) at the Port Talbot site, which were operational until recently. The two BFs had a capacity for 5 million tpy, but the company did not use the whole of it and explained that the annual output from the two BFs did not exceed 3 million tpy.
BF5 was closed in July this year, and BF4 was closed in September.
The Port Talbot site produced mainly hot-rolled coil and cold-rolled coil.
According to the contract with Tenova, the Port Talbot site will also receive new ladle metallurgy furnaces, which will allow the production of more complex grades required by manufacturers in the UK and other countries.
“Today marks an important milestone in making low-CO2 steelmaking a reality in Port Talbot, as well as reducing the UK’s carbon emissions and supporting our customers with their own carbon reduction targets,” T V Narendran, chief executive officer of Tata Steel, said during the signing of the contract.
“Technology like the furnaces made by Tenova is critical to decarbonizing the industry, unlocking its potential to provide skilled jobs and creating economic stability for future generations of steelworkers in South Wales,” Jonathan Reynolds, UK Business and Trade Secretary, said.
UK steel sector will face increased demand for scrap
Tata Steel’s new EAF will recycle 2 million-2.5 million tonnes of UK-sourced scrap every year — equivalent to about 2.5 million cars or 250 Eiffel Towers, the company said.
Using predominantly UK-produced scrap means that the company would need to buy high-quality scrap grades with lower impurities that are suitable for flat steel production.
The UK is a net scrap exporter, but with new EAF-based steelmaking capacities coming online, it could become an importer of certain grades, sources suggested.
Another UK steel producer, British Steel also plans to switch to EAF by 2025.
