bulletin cover story Refractory issues related to the use of hydrogen as an alternative fuel By James G. Hemrick With the increased interest in using hydrogen as an alterna- tive fuel to reduce carbon dioxide emissions, this article looks at some of the effects on refractory ceramic lining systems when industrial furnaces are fired on hydrogen in place of or in addition to traditional fuels. The United States Department of Energy (DOE) has devoted significant interest and resources to the use of hydrogen as an alternative industrial fuel source because it is known to create only water when combusted and, depending on its production method, generates little or no carbon dioxide. Yet while much attention is being given to the economics and feasibility of the supply and utilization of hydrogen as an alternative fuel, less consideration is currently aimed at the effects such fuel changes may have on industrial processes where they are implemented. Industrial processes are currently based largely on the use of fossil fuels, which are responsible for a major por- tion of industrial emissions. According to a 2019 report by Freidlingstein et al., industrial emissions accounted for 22% of global carbon dioxide emissions, with fuel used for process heating accounting for 42% of industrial emissions globally and 58% in the United States.1 Yet, the industrial sector may be more reticent than other sectors (such as electric power or transportation) to invest in alternative fuels that may reduce emissions due to the high capital investments required and long operating lifetimes of equipment, the inability to pass on price premiums to con- sumers, and the specific technical requirements that limit the options for substituting alternative fuel streams.2 Such aspects of industrial heating that may be relevant include the absolute temperature, heat flux, heat availability, and heat reliability sup- plied by the fuel source. All these aspects can be issues when considering using hydrogen as an alternative energy source. 26 www.ceramics.org | American Ceramic Society Bulletin, Vol. 101, No. 2PDF Image | hydrogen as an alternative fuel
