Ovako Adds 20MW Alkaline Water Electrolyzer for Hydrogen Production

HTD Size-PR LogoOvako, a European manufacturer of engineering steel with a North American presence, will receive a 20MW alkaline water electrolyzer by the end of 2022. The electrolyzer will be used at their plant in Hofors, Sweden for hydrogen heating of steel prior to rolling and hot forming.

Ovako Hofors

"In June," says Rickard Qvarfort, president of the business unit at Ovako Hofors, "we announced our collaboration with the Volvo Group, Hitachi Energy, H2 Green Steel and Nel Hydrogen with the purpose to invest in fossil-free hydrogen in Hofors[. . .] We are now very pleased to have reached this important milestone of the project. The electrolyzer technology will enable us to eliminate CO2 for heating steel before rolling."

Nel Hydrogen

Nel Hydrogen Electrolyser AS, a division of Nel ASA, is scheduled to deliver the electrolyzer in 2022 for first hydrogen production in 2023. The electrolyzer will produce oxygen and hydrogen for Ovako's steel-heating processes and will decrease CO2 emissions by 50%.

"We are very excited to announce the delivery of electrolyzer equipment to Ovako, and this groundbreaking project," Jon André Løkke, CEO at Nel Hydrogen explains. "There is huge potential in reducing CO2-emissions from steel-heating processes through the use of green hydrogen, there are numerous similar sites with equally large potential for decarbonization across Europe and the rest of the world."

Ovako’s Transformational Heat Treat Benefits with Electric Retrofit

HTD Size-PR LogoFor Ovako, a centuries old manufacturer of engineering steel, innovative approaches to producing their product has taken the form of electrifying their roller hearth furnaces over the course of the past decade.

The process of converting to electric heating began in 2014, each furnace installed with up to 86 Tubothal® metallic heating elements from Kanthal. Now, 14 roller hearth furnaces are electrified. The estimated CO2 savings is around 1,400 to 2,000 tons per year per furnace.

“[In] our heat treatment shop in Hofors,” shares Anders Lugnet, a furnace technology specialist at Ovako (pictured above), “we originally had around 450 gas burners, and there was always a problem somewhere in one of them. Since replacing them with 300-odd Tubothal® elements, the daily maintenance is simply not there. Occasionally, an element needs to be replaced, but it is nothing compared to the way it was.”

He continues that, previously, NOx and CO2 emissions were problematic. But with green electricity, emissions are zero, and with no flue-gas losses, total efficiency has improved significantly.

Innovations to Test the Limits of Hard Metals

Head of Group R&D
Ovako

An international technology service provider and materials science startup located in Cambridge, UK has formed a new technical collaboration with Ovako, a manufacturer of engineering steel with locations in North America. The collaboration is focused on extending the startup's new metal testing technology to be able to test very hard metals, including novel grades.

Testing the steel manufacturer's Hybrid Steel® is a particular focus of the collaborative efforts with Plastometrex. The novel grade results from the first successful combination of two well-established precipitation strengthening mechanisms – i.e. simultaneous hardening by both carbides and intermetallic precipitations. It is designed to meet the demands of high-stress, elevated-temperature applications where mechanical strength is critical.

Plastometrex

Patrik Olund, vice president and Head of Group R&D of Ovako, comments on the technology, "Their platform methodology and innovative product provide a much-needed tool for both metallurgy R&D and production activities. By extending the capability of the technology to test the hardest metals, we will be able to use the technology to rapidly characterize and optimize our products as well as the novel Hybrid Steels."

From the Ovako collaboration, Plastometrex will release a product update that will enable the device to test the vast majority of very hard engineering metals. Professor Bill Clyne, Chief Scientific Officer and leader of Plastometrex's research and development activities, commented, "[OVAKO] are a company with excellent scientific capabilities and a forward-thinking approach. Our collaborative work has been highly fruitful and directly resulted in capability improvements to our flagship product, which will soon be able to test very hard metals."
