Grant funding opportunity for applied research projects supporting California's transition away from fossil gas. The solicitation funds research meeting two initiatives: (1) Location-Specific Analysis of Decommissioning to Support Long-Term Gas Planning (Gas R&D Budget Plan FY 2021-2022), and (2) Scaled-Up Gas Decommissioning Pilots and Integrated Planning Tools (Gas R&D Budget Plan FY 2022-2023). The focus is on understanding and supporting both the prerequisites to and impacts of conversion from gas end uses in the residential and commercial sectors, considered in the context of a transition from fossil gas use overall. The State of California aims to greatly decrease reliance on fossil gas through electrification of current gas end uses, decommissioning gas system infrastructure, reducing gas-fired power generation, and potentially by integrating lower-carbon gases into the utility gas system or deploying other alternatives to fossil gas.
