(343c) End-Use of Hydrogen in Decarbonizing Buildings and Industrial Manufacturing

Industry and buildings sectors together represent 70% of U.S. primary energy consumption. The generation and use of heat is the most significant end use of energy in both sectors, accounting for 23% of direct GHG emissions. Approximately 90% of manufacturing process heat energy is provided by fossil fuels while 50% of buildings consume natural gas for space and water heating. Decarbonization efforts thus require energy efficient heating and drying technologies capable of operating on low/zero carbon fuels such as hydrogen. Globally, businesses, governments, and academics are working to harness the power of hydrogen. Substitution of hydrogen with natural gas has the potential to eliminate 1500 MMT of CO₂, annually. Novel technologies capable of effectively utilizing hydrogen in heating and power generation applications will be discussed. Technological advancements in direct heating equipment for safely and effectively utilizing hydrogen fuel in both industry and buildings will be presented. The overall value proposition of using hydrogen in combined heat and power applications for deployment in both industries and buildings will be presented.
