; (F) saline formations in both sedimentary and basaltic geologies; (G) geologic systems that may be used as engineered reservoirs to extract economical quantities of brine from geothermal resources of low permeability or porosity; and (H) geologic systems containing in situ carbon dioxide mineralization formations. (c) Large-Scale carbon sequestration demonstration program (1) In general The Secretary shall establish a demonstration program under which the Secretary shall provide funding for demonstration projects to collect and validate information on the cost and feasibility of commercial deployment of large-scale carbon sequestration technologies. (2) Existing regional carbon sequestration partnerships In carrying out paragraph (1), the Secretary may provide additional funding to regional carbon sequestration partnerships that are carrying out or have completed a large-scale carbon sequestration demonstration project under this section (as in effect on the day before the date of enactment of the Enhancing Fossil Fuel Energy Carbon Technology Act of 2019 ) for additional work on that project. (3) Demonstration components Each demonstration project carried out under this subsection shall include longitudinal tests involving carbon dioxide injection and monitoring, mitigation, and verification operations. (4) Clearinghouse The National Energy Technology Laboratory shall act as a clearinghouse of shared information and resources for— (A) existing or completed demonstration projects receiving additional funding under paragraph (2)
