Innovations driving cost reductions in energy storage technologies are crucial for achieving the target of affordable long-duration energy storage. Here are some key innovations across different technology families:
Electrochemical Energy Storage
- Improvements in Electrolytes and Cell Packaging: Enhancements in battery electrolytes and cell packaging can significantly reduce costs for technologies like lithium-ion, sodium, and lead-acid batteries. For instance, incorporating sodium or lithium into active materials can improve efficiency and reduce costs.
- Supercapacitors: Including zinc in the active materials can enhance the performance and cost-effectiveness of supercapacitors.
Chemical Energy Storage
- Hydrogen Storage: Innovations in above-ground and below-ground hydrogen storage can reduce costs. This includes improving electrolysis processes for hydrogen production.
Mechanical Energy Storage
- Compressed Air Energy Storage (CAES): Innovations in CAES involve more efficient compression systems and exploiting underground caverns for air storage.
- Pumped Hydro Storage: Improvements in turbine efficiency and reservoir design can enhance cost-effectiveness.
Thermal Energy Storage
- Molten Salt Systems: Enhancements in molten salt thermodynamics and design improve thermal storage efficiency, reducing costs.
General Innovations
- Scaling and Automation in Manufacturing: Increasing production scale and automating manufacturing processes can significantly reduce costs across all technologies.
- Demonstration Projects: Real-world demonstration projects help validate innovations and attract investment, driving down costs through proven efficiency.
- Innovation Portfolios: Implementing a diverse portfolio of innovations can achieve cost reductions of up to 85%, depending on the technology.
These innovations are essential for meeting the $0.05/kWh target set by initiatives like the Department of Energy’s Long Duration Storage Shot.
