Economic Competitiveness
A lower LCOS makes LDES technologies more attractive for grid operators and developers. The U.S. Department of Energy’s $0.05/kWh LCOS target aims to enable LDES to compete with fossil fuels and support renewable integration. Current projections show most technologies exceeding this target without innovation, but strategic advancements could bring pumped hydro, compressed air, and flow batteries below $0.05/kWh by 2030. Technologies like sodium-ion and lead-acid batteries may approach $0.10/kWh, narrowing the cost gap.
Technology Prioritization
LCOS metrics drive investment toward innovations with the highest cost-reduction potential. For example:
- Sodium-ion and lead-acid batteries show the greatest LCOS reduction potential (up to -$0.31/kWh) through material optimization and efficiency gains.
- Hydrogen storage faces higher baseline costs but benefits from innovations in compression and containment.
- Lithium-ion batteries, while dominant in short-duration storage, remain less competitive for long-duration applications due to higher LCOS.
Market Adoption Barriers
High LCOS delays LDES deployment by limiting cost recovery in energy markets. The shift from levelized cost of energy (LCOE) to LCOS in DOE assessments reflects a focus on storage-specific costs, including charging expenses and equipment replacement. Without LCOS reductions, utilities may favor cheaper short-duration storage or fossil-fuel peaking plants.
Policy and Innovation Alignment
The Long Duration Storage Shot initiative underscores the need for targeted R&D to address LCOS bottlenecks, such as improving energy density and cycle life. Achieving sub-$0.05/kWh LCOS could unlock LDES for multi-day renewable firming, seasonal storage, and grid resilience.
In summary, LCOS determines the economic viability of LDES technologies, guiding innovation priorities and investment decisions critical for their widespread adoption.
