Grants to California private and public entities for research projects to study the use of natural gas blends in industrial and commercial appliances. Funding is intended to study which blends are the most energy-efficient and can be used with minimal modifications to existing appliances.
The purpose of this solicitation is to fund a technical study to identify the impact of the potential use of hydrogen and hydrogen-natural gas blends on existing appliances as a potential decarbonization strategy for large commercial buildings and the industrial sector. The study will identify operating parameters such as the maximum concentration of hydrogen that can be handled by existing equipment with and without modification. This study will inform policymakers and the private sector of the potential for hydrogen and hydrogen-natural gas blends as a decarbonization strategy for industrial and large commercial building applications.This solicitation will result in a techno-economic study that will identify the impact of hydrogen and hydrogen-natural gas blends on existing appliances used in the large commercial building and industrial sectors. It will also identify operating parameters such as the maximum concentration of hydrogen that can be handled by this equipment with and without modification.The use of hydrogen and hydrogen-natural gas blends could change combustion characteristics because of the differences in physical and chemical properties. The addition of hydrogen could also pose safety and performance issues such as embrittlement, flame flashback, flame stability, wet flame gas, gas flow changes, reduced radiative heat transfer, impacts on criteria air pollutant emissions and energy efficiency, system differences in control and safety, and other unforeseen complications in end-use applications which could change the characteristics of the resulting product.The research must address these knowledge gaps and identify key benefits, challenges and potential solutions associated with using hydrogen and hydrogen-natural gas blends in end-use appliances for large commercial buildings and industrial applications. The result will inform policymakers and the private sector of the technical and economic feasibility of this strategy and identify additional research, demonstration, and infrastructure necessary to enable large-scale deployment. The transfer of knowledge gained from this study is the primary goal.grants for minorities
