Siemens Energy, a prominent energy company, has traditionally concentrated on Proton Exchange Membrane (PEM) technology for the production of green hydrogen. However, the company is considering diversifying its electrolyzer technologies in the future to enhance its offerings and adapt to changing market demands. The Director of Siemens Energy's Hydrogen Division, Alexey Ustinov, anticipates a potential shift in the company's approach, moving away from solely relying on PEM electrolysis due to the need for extreme precision in its production. Currently, Siemens Energy boasts an annual electrolysis capacity of 1 GW. Ustinov predicts that this capacity could triple within a year if the demand for green hydrogen increases significantly, particularly for approved projects. Despite facing competition from Chinese companies that offer more cost-effective solutions, Ustinov remains confident in Siemens Energy's capabilities and its potential for growth and adaptation. The article also delves into the political landscape surrounding the green energy sector, highlighting concerns about the trend towards isolating China in this industry. While recognizing the challenges posed by cheaper Chinese plants, Siemens Energy is preparing to navigate these complexities and maintain its position as a leading player in the field of green hydrogen production.
