Hydrogen has emerged as a vital component in the quest for decarbonizing industry and transportation, leading to a surge in new hydrogen initiatives worldwide. The International Energy Agency (IEA) emphasizes the need for accelerated action to achieve net zero emissions by 2050 and meet the Paris Agreement goals. Electrolysis stands out as a primary 'clean' method to produce hydrogen, particularly through technologies like alkaline electrolysis and proton exchange membrane (PEM) electrolyzers. However, the spotlight is now on Solid Oxide Electrolysis Cells (SOECs), which operate at high temperatures and offer efficiencies of up to 85%, with a target of 90% by 2030. These SOECs, championed by companies like Mitsubishi Heavy Industries (MHI), are seen as a promising avenue to enhance hydrogen production scalability. While SOECs currently contribute only 1% to green hydrogen production, their commercialization is on the rise. MHI is actively developing large modular SOECs with a remarkable efficiency goal, signaling a potential shift towards widespread adoption. Notably, SOECs eliminate the need for precious metals like platinum and iridium, reducing reliance on rare elements and showcasing a sustainable approach to hydrogen generation. The technology's evolution from solid oxide fuel cells (SOFCs) further strengthens its credibility. As the world seeks to diversify electrolysis technologies, innovations like anion exchange membrane (AEM) electrolyzers are also gaining traction. However, the efficiency and maturity of SOECs position them as frontrunners for large-scale hydrogen plants. The industry's collective emphasis on enhancing energy efficiency and reducing carbon footprint underscores the significance of advancing hydrogen production methods, with SOECs leading the charge towards a greener future.
