H.R. 5638 would authorize the appropriation of $150 million annually over the 2017-2020 period for the Department of Energy to perform basic research to develop experimental systems to convert solar energy into chemical energy. Assuming appropriation of the authorized amounts, CBO estimates that implementing H.R. 5638 would cost $579 million over the 2017-2021 period.
Pay-as-you-go procedures do not apply to this legislation because enacting it would not affect direct spending or revenues. CBO estimates that enacting H.R. 5638 would not increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2027.
H.R. 5638 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would impose no costs on state, local, or tribal governments.
