The article discusses the increasing importance of stationary fuel cells, particularly those running on green hydrogen, in addressing global energy security and decarbonisation goals. As the power grid faces challenges from rising demands and digitalisation, fuel cells are being recognized as a viable solution. The market for fuel cells is expected to grow significantly, with projections indicating a value of $8 billion by 2035, growing at a CAGR of 23.7%. Fuel cells are praised for their efficiency and versatility, making them ideal for providing backup and continuous power generation in utilities to ensure grid reliability. They also show promise in sectors such as data centers and telecommunications, where power needs are increasing rapidly. Additionally, fuel cells are being explored in the industrial sector to capture carbon emissions while generating power. Despite challenges in hydrogen infrastructure development, alternatives like direct methanol fuel cells are bridging the gap in the short term. In residential areas, compact and low-noise fuel cells are gaining popularity, particularly in off-grid regions like Japan, aiming for 5.3 million fuel cell units by 2030. When combined with solar power, these fuel cell systems offer energy independence and contribute to carbon reduction. Overall, fuel cells are positioned as a key element in the clean energy transition, driven by commercial demands and the focus on long-term sustainability.
