SubsidieMeestersDual circuit flow battery for hydrogen and value added chemical production
DualFlow combines water electrolysis, battery storage, and decarbonized chemical production into a flexible hybrid system for efficient energy conversion and storage.
Projectdetails
Introduction
DualFlow develops a radically new energy conversion and storage concept that combines water electrolysis, battery storage, and co-production of decarbonized chemicals into one single hybrid technology using water-soluble redox mediators as energy transfer vectors.
System Operation
The system can be operated for:
- Electricity storage
- Energy conversion to hydrogen and value-added chemicals
Energy Storage Operation
During energy storage operation, the system works as a conventional stationary flow battery.
Energy Conversion Process
The energy conversion starts when the battery is full but there is abundant inexpensive green electricity available. At this point, the battery is chemically discharged in a mediated electrolysis to produce hydrogen and value-added chemicals.
Mechanism of Energy Conversion
The energy conversion is realized by pumping charged battery electrolytes through reactors.
- For hydrogen production, the reactor is filled with catalytic particles to catalyze electron transfer and hydrogen evolution.
- For value-added chemical production, the reactor consists of a biphasic system where charged electrolyte oxidizes chemicals in an organic phase. The reaction products are then extracted into the organic phase.
Cost Efficiency
The energy conversion operation requires only reactors and catalysts for hydrogen evolution, indicating that the additive costs of the dual circuit are minimal.
Conclusion
The concept results in a flexible system capable of both energy storage and energy conversion to hydrogen. We strongly believe that this concept offers possibilities to produce inexpensive hydrogen in a flexible manner without utilizing any critical raw materials.
