Technology description

HyTIME starts with a fermentation by specialist, natural bacteria which are selected because their efficient H2 production. Hydrogen and CO2 are the gaseous products from this fermentation whereas the organic acids remain dissolved in the fermentation liquid. Hydrogen is separated from CO2 by a novel process for gas upgrading. The liquid fraction with the organic acids, mainly acetic acid, is sent to a second vessel for AD. In this second step, biogas with methane and CO2 is the gaseous end-product. In HyTIME, biomass is converted to pure H2 and methane and CO2.

Organizative processes to support closing the loops

The efficient extraction of hydrogen from food waste HyTIME chose bacteria of the genus Caldicellulosiruptor because they performed well in earlier experiments on H2 production. The researchers also developed a number of methods to monitor the bioprocess and to collect the H2 gas. Project partners investigated a laboratory-scale bioreactor that performed well in testing. Researchers studied and optimised the processes taking place within this bioreactor prototype. This research will help create new ways to extract value from biological waste, and contribute to answering the growing global demand for H2.
