The Commonwealth Scientific and Industrial Research Organisation (CSIRO) has made significant progress in overcoming the cost barrier to commercial hydrogen production with its tubular solid oxide electrolysis (SOE) technology. Traditional electrolysis methods require large amounts of electricity, making production expensive in markets with high electricity prices. However, the SOE technology, which combines waste heat and electricity, has demonstrated potential in generating hydrogen more efficiently. In a trial with BlueScope Steel, the pilot project achieved a milestone by producing hydrogen with an electrical input of less than 36kWh per kilogram, a notable improvement from the usual 55kWh per kilogram. This breakthrough is crucial for Australia's hydrogen industry, offering a pathway to affordable and renewable hydrogen production at scale to support decarbonisation efforts. CSIRO's senior principal research scientist praised the technology for its performance in hydrogen production, electrical efficiency, and reliability. BlueScope Steel also expressed optimism, viewing hydrogen as a key element in its journey towards net zero emissions. The successful outcomes of the pilot project have been well-received, indicating a bright future for hydrogen production in Australia's heavy industry sector.
