Lower Austria’s first hydrogen storage facility was officially opened in St. Pölten. According to Governor Mikl-Leitner, this HydroSolid hydrogen storage facility is considered a significant step in the country’s energy transformation. Udo Landbauer was represented by Christian Hafenecker, Chairman of the Parliamentary Committee for Research, Innovation and Digitization. “Hydrogen is a contemporary issue, and it is urgently necessary to find innovative solutions. This facility can potentially be a global pioneer,” said Hafenecker. It is particularly pleasing that this innovation comes from Lower Austria. Hydrogen as the drive of the future Hydrogen is the most common element in the universe and…

Due to rising CO2 prices, the economic success of energy-intensive companies in Saarland will depend on the shift to hydrogen as an energy carrier. Jürgen Barke (SPD), the Minister of Economics, expressed this belief, announcing that Saarland’s hydrogen strategy will be revised in close collaboration with local businesses. Hydrogen Expansion Must Succeed by 2027 From 2027 onwards, the steel industry in Saarland aims to gradually transition from CO2-intensive steel production using coke to a more climate-friendly approach utilizing hydrogen. The steel industry in Saarland alone will require 120,000 tons of hydrogen annually. The necessary production facilities (electrolyzers) and the planned…

Morocco has unveiled its ambitious “Green Hydrogen Morocco Offer.” This program, projected to attract significant investments over the next decade, could transform the country’s energy and economic landscape. “We are not talking merely about a new industrial sector, but a true economic growth driver for Morocco,” a Ministry of Energy, Mines, and Environment member told Afrik. Although specific figures have not been disclosed, the Moroccan government aims to create thousands of direct and indirect jobs in the sector by the decade’s end. By 2030, the Kingdom plans to supply 4% of the global green hydrogen demand, a rapidly growing market.…
