Tobias Greitemeier, an employee at Siemens Energy's hydrogen electrolyser production facility in Berlin, shares his excitement about transitioning from turbine manufacturing to the cutting-edge field of hydrogen production. The article emphasizes the role of hydrogen in decarbonizing industrial sectors and complementing renewables in the energy mix. Siemens Energy's facility in Berlin utilizes a combination of manual and automated processes, with robots assisting in coating proton exchange membranes (PEMs) with precious metals like platinum and iridium. The electrolyser stack production at the facility is projected to reach over three gigawatts by 2025 to meet the growing demand for hydrogen. The collaboration between Siemens Energy and Air Liquide aims to further scale up hydrogen production and strengthen this future technology. Training programs like the 'H2 Academy' are highlighted as essential for developing expertise in hydrogen production, bridging the gap as there is currently no specific public training program for this field in Europe. The article showcases Tobias' journey and dedication to shaping the future of energy through his work in hydrogen production, reflecting on the immense support and fascination he finds in his new role. Siemens Energy's commitment to decarbonization and the energy transition is underlined through investments in innovative technologies and workforce development initiatives.
