Additional research and demonstration funding is needed to develop new lower-cost pathways to produce hydrogen from both fossil and renewable sources; to enable the long-term storage of hydrogen at scale; to ensure we leverage existing natural gas infrastructure to deliver hydrogen safely and efficiently; and to safely use hydrogen The Honorable Marcy Kaptur The Honorable Mike Simpson March 15, 20. [...] Comprehensive planning approaches for transitioning segments of the economy (e.g., the power sector) using hydrogen and other low-carbon fuels (e.g., ammonia) should be part of the program, including analysis of the infrastructure required to store and transport these fuels and the conversion of today’s fossil fuel end users, energy-intensive industries, and disadvantaged communities alike, to saf. [...] The Committee encourages the Department to continue to explore research and development that can advance systems and appliances to meet consumer demand for high efficiency and environmentally friendly products in residential and commercial building applications, including dual fuel space heating and water heating systems, thermally-driven heat pumps, increased utilization of renewable fuels and hy. [...] The Committee also supports competitively awarded research and development activities under any remaining funds, The Honorable Marcy Kaptur The Honorable Mike Simpson March 15, 2024 Page 5 coordinated with the Offices of Nuclear Energy and Energy Efficiency and Renewable Energy, to advance the maturity of supercritical CO2 cycles. [...] To assist in technology solutions, particularly around syngas clean-up and lower carbon intensities for RNG and hydrogen produced, the Committee recommends $20,000,000 to perform R&D of technologies to advance the deployment of conversion and purification processes to advance the supply of RNG and clean hydrogen, including the development of gasification and clean up technologies that can successf.
