Given the urgent need to tackle climate change and the depletion of natural resources, it is now vital to find renewable energy sources. Hydrogen stands out as a solution for decarbonisation. IRD scientists Pierre-Pol Liebgott and Yannick Combet-Blanc (MIO) - from the BIOTEC H2 International Joint Laboratory - are developing a biological hydrogen production process using food waste and marine micro-organisms. This project, supported by the IRD's South-East regional delegation, is just a few clicks away.
