ReZilient aims to develop a novel Zn-air flow battery for long-duration energy storage, enhancing grid reliability and reducing costs with a focus on improved efficiency and sustainability.
Projectdetails
Introduction
The penetration of renewable energies into the electric grid increases the demand for energy storage to ensure reliable power supply, grid resiliency, and cost reductions. Long-duration and long-term energy storage (LDES and LTES) can bridge the intermittency of renewable sources and reduce the risks incurred by diminished fossil-fuel baseload generation.
Energy Storage Options
Electrochemical energy storage (EES), or Li-ion batteries (LIBs), are considered for short-duration energy storage (4-6 hours). When discussing seasonal storage, hydrogen storage is usually the preferable option.
Project Goal
The goal of ReZilient is to fill the gap between short-term EES and long-term hydrogen storage by developing and demonstrating at lab-scale (0.5-1.5kW/6kWh) a completely new Zn-air flow battery technology.
Cost Estimates
The estimated capital cost for large-scale deployment is approximately 80 €/kWh, with a levelized cost of storage <0.5 €/kWh/cycle (based on a 100 kW/1000 kWh system, 1 week discharge duration).
Innovative Strategy
A disruptive redox-mediated strategy for enhanced charge transfer processes is employed with the goal of:
- Confining the Zn/Zn2+ redox reaction in the negative reservoir (filled with a semi-solid zinc solution).
- Eliminating the electroplating process inside the cell (no dendrites) to improve battery lifetime.
This will allow discharge times beyond days, contrary to conventional zinc-based batteries where long discharge is hampered by the formation of a cm-thick zinc anode.
Potential Impact
If successful, the technology has disruptive potential in terms of:
- Extremely low levelized cost of storage
- Extended storage time
- Recyclability
- Use of non-critical raw materials
Future Development
A pilot concept design of the cell will be conceived after the demonstration of the technology. The output of this design will lead to an update of the business case for the distribution network operators and potential customers.
