Hydrogen researchers at Graz University of Technology (Austria), together with the Graz-based start-up Rouge H2 Engineering , have developed a cost-effective process for the decentralized production of high-purity hydrogen using chemical looping. Currently, hydrogen is mainly produced centrally from fossil resources and compressed or liquefied in an expensive and energy-intensive process in order to be able to supply it to filling stations. Additionally, expensive infrastructure with high investment costs is needed there to store large quantities of hydrogen. The process is well established and economically efficient due to the moderate costs for production, the feedstock and the existing infrastructure. However, centralized large-scale production implies the major drawback of emitting vast amounts of greenhouse gases during the transport over wide distances to the consumer using trucks. Additionally, large amounts of hydrogen have to be stored in pressurized form on site at the customer to compensate for fluctuations in consumption. Both […]
