Green Hydrogen and Platform Chemicals from Agricultural Residues

The efficient utilisation of bio-based resources is essential for achieving a sustainable, carbon-neutral society. AGRI-WASTE2H2 will focus on straw-derived cellulose – an abundant but underexploited agricultural side-product – as feedstock in an advanced electrochemical process, tailored for enhanced efficiency in the production of green hydrogen with significantly reduced energy consumption compared to standard water electrolysis. At the same time, the process will concurrently produce valuable platform chemicals and materials. AGRI-WASTE2H2 relies on the combined expertise of researchers in three Nordic-Baltic countries – Finland, Sweden and Estonia. The Synthetic Flow Chemistry group at Tallinn University of Technology, Estonia, will focus on transferring the electrochemical oxidation of cellulose into the flow regime, aiming to achieve high efficiency and productivity of the developed transformation. The scaling-up process in flow is a key step for a successful industrial application. AGRI-WASTE2H2 capitalises on the abundance of renewable electricity and agricultural side-streams in the Nordic-Baltic area to produce fuel and chemicals, thereby alleviating the region’s dependence on import of fossil feedstocks. As such, the project will result in tools for reduced CO2 emissions and increased regional resilience, while spurring the growth of new green industries of particular benefit for rural areas. The collaboration between researchers three Nordic-Baltic countries will enable results beyond what the individual partner can achieve alone and promote regional mobility and new collaborations. By leveraging our specialised know-how, we aim to drive innovation tailored to our regional needs and strengths.
