Battery storage is increasingly recognized as a viable option to reduce emissions from peaking plants compared to other technologies. Here’s a comparison of battery storage with other approaches:
Comparison Overview
| Technology | Emissions Reduction | Key Benefits |
|---|---|---|
| Battery Storage | Up to 60% reduction | Immediate dispatch capability, reduces startup emissions, utilizes existing infrastructure. |
| Hybridization | Significant reduction | Combines fossil fuel plants with battery storage to minimize startup emissions. |
| Replacement | Complete elimination | Replaces peaking plants with battery storage, avoiding emissions entirely. |
Key Points
- Battery Storage: Adding batteries to peaking plants can significantly reduce both carbon emissions and localized pollution. Batteries can dispatch instantly, preventing peakers from idling and emitting pollutants while waiting to be called upon. Lithium-ion batteries, especially those with 2-8 hour durations, can cover about 50% of peaker plant restarts, cutting emissions by up to 60%.
- Hybridization: This approach involves pairing fossil fuel plants with battery storage. It operates similarly to hybrid vehicles, reducing emissions by allowing batteries to handle immediate power needs while the fossil fuel component kicks in when necessary. This strategy is controversial as it may prolong the lifespan of polluting peaker plants.
- Replacement with Battery Storage: Completely replacing fossil-fueled peakers with battery storage offers a cleaner alternative. This approach avoids the environmental and health impacts associated with peaking plants. In places like Maine, new 4-hour battery storage has been shown to be economically viable and environmentally beneficial for replacing aging peakers.
Conclusion
Battery storage emerges as a promising technology for reducing emissions from peaking plants due to its immediate dispatch capabilities and potential for significant emissions reduction. However, the long-term goal should be to replace peaking plants entirely with battery storage to achieve complete decarbonization and eliminate related health risks.
