Hydrogen electrolysers: Breathing life into a net zero future
The article Hydrogen Electrolysers: Breathing life into a net zero future by Zeeshan Sami Khan, Senior Hydrogen Analyst at PTR Inc. explains Hydrogen, particularly through electrolysis, is gaining prominence as a key solution for decarbonizing traditionally polluting industries. This transition is evident in sectors like steel-making and transportation, where hydrogen is replacing conventional processes and fossil fuels, aligning with countries’ net-zero emission goals. The article provides a comparative analysis of different hydrogen electrolyser technologies, including Anion Exchange Membrane (AEM), Proton Exchange Membrane (PEM), Alkaline and Solid Oxide Electrolysis Cells (SOEC). The electrolyser manufacturing landscape includes both veteran players such as Siemens Energy and NEL Hydrogen, as well as upstarts like Enapter and Ohmium. Predictions from PTR suggest that the total electrolyser installed capacity could reach 2.5GW by the end of 2023 and 150GW by 2030. Moreover, PTR estimates that global electrolyser production capacity will rise from 1GW/year in 2022 to 85GW/year in 2030. Despite existing challenges, such as high costs and reliance on rare earth metals, the electrolysis sector presents untapped opportunities for innovation, collaboration, and transformative changes. This outlook promises an industry revolution, contributing significantly to the reshaping of the world’s energy landscape and fostering a more sustainable and decarbonized future.
