Luxembourg's ArcelorMittal has diversified its portfolio by acquiring a 28% stake in the French company Vallourec, known for manufacturing tubes for oil and gas applications. This move positions ArcelorMittal to capitalize on the growing demand for greener energy solutions, including hydrogen, geothermal, and carbon capture technologies. Vallourec's steel tubes, which compete with Tenaris, are particularly popular in the Americas, presenting a lucrative market for ArcelorMittal's expansion. Vallourec is expected to boost its earnings from green-energy infrastructure to 10-15% by the end of the decade, aligning with the global shift towards sustainable practices. ArcelorMittal anticipates significant financial gains from this investment, with expected profits from Vallourec next year and a positive outlook on the company's performance. Moreover, Luxembourg is making strides in the clean-energy sector, with plans to integrate into a European network for clean-hydrogen production. The establishment of a Luxembourg Hydrogen Valley, supported by EU funding, aims to produce industrial quantities of hydrogen by 2026, further promoting the adoption of hydrogen as an alternative energy source. This initiative reinforces Luxembourg's commitment to reducing reliance on traditional hydrocarbons for transportation and industrial purposes, highlighting the country's progressive approach towards sustainability and innovation.
