Milestones:
Short Term (six months to two years)
• Develop a techno-economic analysis framework
for evaluating the viability of advanced storage
technologies
• Computer-model promising concepts to target for
initial experimentation
• Demonstrate promising bench-scale prototypes
for short-, mid-, and long-duration storage
10-year goal:
• Develop next-generation energy storage
technologies and manufacturing processes
to sustain U.S. leadership in energy storage
science and technology and meet U.S.
market demand in transportation and longduration stationary applications.
The Challenge:
• Enable penetrations >60% of renewable
resources able to store excess generation
for other times or locations, and to shift
power seasonally
• Economically address the need for longduration energy storage to electrify
transportation and provide sustainable,
resilient electricity
Research Summary:
• ETA is exploring technologies that meet the
demand for economical and geographically
flexible storage:
• Electrochemical energy storage – Non-lithium
(Li)-ion electrochemical storage technologies
that meet demand for various applications
and cycle regimes
• Chemical energy storage – Cost reductions in
the synthesis of hydrogen or other energydense carriers and advancements to reduce
component and manufacturing
• Thermal energy storage – New concepts and
technologies for thermal energy storage
and approaches to optimize materials and
designs
8 | ETA Strategic Plan 2021-2030
• Integrate efforts with the national Energy Storage
Grand Challenge (ESGC) to obtain support for
post-bench-scale concepts
• Within two-years, we will identify and develop
prototypes of promising energy storage
technologies that can be integrated into ESGC
efforts.
Medium Term (three to five years)
• Support a research program that establishes ways
in which advanced energy storage systems may
support future electricity supply and demand, and
account for factors such as mixed short- and longduration usage and future scenarios for energy
supply sources
• Investigate battery system charge-discharge
performance, longevity, degradation, safety, and
overall materials lifecycle
• Begin transitioning early energy storage
technologies toward commercialization through
programs such as Cyclotron Road and ARPA-E
• Within five years, we will develop a research
program that identifies how energy storage
technologies enable restructuring of key parts of
the electric grid, and facilitate their widespread
commercialization.
Long Term (five years and beyond)
• Establish a clear methodology and software
implementation that helps stakeholders
understand the energy storage systems’
applications and economic value under specific
scenarios, and their end-of-life characteristics
• Commercialize Berkeley Lab technology
prototypes and initial deployments
• Establish an Energy Storage Hub for technologies
spanning time and length scales
