Dr. Jwa Eunjin and her team at the Korea Institute of Energy Research (KIER) achieved a breakthrough in clean energy technology by enhancing a bio-electrochemical cell for more efficient hydrogen production from microorganisms in waste. Conventional hydrogen production methods face challenges like carbon emissions and high energy demand. The newly developed Zero-Gap technology minimizes electrical resistance, enabling faster electron transfer and increased hydrogen productivity. This innovation addresses power loss issues, leading to 1.2 times higher hydrogen productivity and 1.8 times higher electron production compared to existing processes. The design ensures complete adhesion between electrodes and separators, improving efficiency even in large-scale implementations. The successful pilot-scale experiments confirm the technology's viability, offering a significant step towards large-scale commercialization. Dr. Jwa Eunjin highlighted the environmental and economic benefits of this advancement in clean hydrogen energy production, emphasizing its role in achieving carbon neutrality and transitioning to a hydrogen-based society.
