13. Flywheel storage
Characteristics
 Short-term storage (sec-minutes)
 Large number of full cycles (>100.000)
 Higher capacity than supercaps
Grid power management
 Economically viable business model?
E.g. beacon Power (US)
 16.000 rpm
 160kW over 30min
and Stornetic (GE)
 45.000 rpm
 Modules of 22kW
 Up to 28 modules (5.2MWh/day)

16. Structural batteries
Opportunities:
 Optimise the mechanical structure
 Optimise the battery materials (cathode/electrode/electrolyte)
UGent expertise: composite materials
 Prof Joris Degrieck, Wim Van Paepegem
 FEM tools: structural design (fatigue and impact)
 Material characterisation

17. (Structural) batteries
Opportunities:
 Optimise the mechanical structure
 Optimise the battery materials (cathode/electrode/electrolyte)
UGent expertise batteries:
 Prof Christophe Detavernier, (SBO-SOS-Lion project, coord. IMEC)
 Atomic Layer Deposition (ALD)
– Very thin uniform layers with perfect step coverage
– Deposit anode/electrolyte/cathode stack on 3D subst.
 Battery characterisation
– Argon-filled gloveboxes
– Thin-film Li-ion batteries & powder batteries.
– Potentiostat/galvanostat (cyclic voltammetry,
galvanostatic charge-discharge).
 Unique setup for in-situ XRD during battery testing

18. (microbial) electrochemical cells for P2P
(microbial) electrochemical processes?
Microbial Electrolysis (MES)

19. (microbial) electrochemical cells for P2P
UGent: expertise
 Prof Korneel Rabaeys
 Prof Lieven Van De Velde
Excess electrical energy  products
 E.g. CH4 production
 E.g. on-site NaOH production for cleaning
 Capronic acid production from waste streams
Characteristics and challenges
 Don’t store the electrical energy, but store the end-product
 One-way storage: no back-conversion to electricity
 Membrame technology?
 Tunability?  to allow for max. integration in the grid
