enhanced geothermal systems,
including—
(1)
reservoir stimulation;
(2)
drilled, non-stimulated (e.g. closed-loop) reservoir technologies;
(3)
reservoir characterization, monitoring, and modeling and understanding of the surface area and volume of fractures;
(4)
stress and fracture mapping including real time monitoring and modeling;
(6)
three and four-dimensional seismic imaging and tomography;
(7)
well placement and orientation;
(8)
long-term reservoir management;
(9)
drilling technologies, methods, and tools;
(10)
improved exploration tools;
(11)
zonal isolation; and
(12)
understanding induced seismicity risks from reservoir engineering and stimulation.
(c)
Frontier observatory for research in geothermal energy—
(1)
In general— The
Secretary shall support the establishment and
construction of up to 3 field research sites, which shall each be known as a “Frontier Observatory for Research in
Geothermal Energy” or “FORGE” site to develop, test, and enhance techniques and tools for enhanced
geothermal energy.
(2)
Duties— The
Secretary shall—
(A)
provide financial assistance in support of research and development
projects focused on advanced monitoring technologies, new technologies and approaches for implementing multi-zone stimulations, nonstimulation techniques, and dynamic reservoir modeling that incorporates all available high-fidelity characterization data; and
(B)
seek opportunities to coordinate efforts and share information with domestic and international partners engaged in research and development of
geothermal systems and related technology, including coordination between FORGE sites.
(3)
Site selection— Of the FORGE sites referred to in
paragraph (1), the
Secretary shall—
(A)
consider applications through a competitive, merit-reviewed process, from
National Laboratories, multi-institutional collaborations, institutes of higher education and other appropriate entities best suited to provide national leadership on
geothermal related issues and perform the duties enumerated under this subsection;
(B)
prioritize existing field sites and
facilities with capabilities relevant to the duties enumerated under this subsection;
(C)
determine the mission need for and potential location of subsequent FORGE sites following the completion of
construction and one year of operation of two FORGE sites; and
(D)
ensure geologic diversity among FORGE sites when developing subsequent sites, to the maximum extent practicable.
(4)
Existing forge sites— A FORGE site already in existence on December 27, 2020, may continue to receive support.
(5)
Site operation—
(A)
Initial duration— FORGE sites selected under
paragraph (3) shall operate for an initial term of not more than 7 years after the date on which site operation begins.
(B)
Performance metrics— The
Secretary shall establish performance metrics for each FORGE site supported under this paragraph, which may be used by the
Secretary to determine whether a FORGE site should continue to receive funding.
(6)
Additional terms—
(A)
In general— At the end of an operational term described in
subparagraph (B), a FORGE site
may—
(ii)
subject to appropriations and a merit review by the
Secretary, operate for an additional term of not more than 7 years.
(B)
Operational term described— An operational term referred to in
subparagraph (A)—
(i)
in the case of an existing FORGE site, is the existing operational term; and
(ii)
in the case of new FORGE sites selected under
paragraph (3), is the initial term under
paragraph (5)(A) or an additional term under subparagraph (A)(ii) of this paragraph.
(7)
Funding—
(A)
In general— Out of
funds authorized to be appropriated under
section 17202 of this title, there shall be made available to the
Secretary to carry out the FORGE activities under this
paragraph—
(i)
$45,000,000 for fiscal year 2021;
(ii)
$55,000,000 for fiscal year 2022;
(iii)
$65,000,000 for fiscal year 2023;
(iv)
$70,000,000 for fiscal year 2024; and
(v)
$70,000,000 for fiscal year 2025.
(B)
Considerations— In carrying out this subsection, the
Secretary shall consider the balance between
funds dedicated to
construction and operations and research activities to reflect the
state of site development.
(d)
Enhanced geothermal systems demonstrations—
(2)
Projects—
(B)
(i)
collectively demonstrate—
(I)
different geologic settings, such as hot sedimentary aquifers, layered geologic systems, supercritical systems, and basement rock systems; and
(II)
a variety of development techniques, including open hole and cased hole completions, differing well orientations, and stimulation and nonstimulation mechanisms; and
(ii)
to the extent practicable, use existing sites where subsurface characterization or
geothermal energy integration analysis has been conducted.
(C)
Eastern demonstration— Not fewer than 1 of the
demonstration projects carried out under
subparagraph (A) shall be located an area east of the Mississippi River that is suitable for enhanced
geothermal demonstration for power, heat, or a combination of power and heat.
(3)
Funding— Out of
funds authorized to be appropriated under
section 17202 of this title, there shall be made available to the
Secretary to carry out the demonstration activities under this subsection $21,000,000 for each of fiscal years 2021 through 2025.
