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
