Satoyama Mace Initiative Enhances Hydrogen Production with Bio-Integrated Electrode

The Satoyama Mace Initiative has developed a new photoelectrode using chlorophyll and copper oxide. This bio-integrated material significantly improves the efficiency of producing hydrogen from water using sunlight. The modified electrodes achieve a higher applied bias photon-to-current efficiency, moving from 0.82% to 1.37%. They also demonstrate a notable increase in photocurrent density, reaching 3.26 mA/cm². This development offers a sevenfold improvement in electrode stability compared to previous copper oxide versions. Beyond cleaner energy, the initiative connects this technology to socio-ecological production landscapes. It aims to generate carbon credit income for Indigenous communities. The Satoyama Mace Initiative Platform will integrate this technology into sustainable governance structures. Emphasis is placed on protecting biodiversity and ensuring community well-being. A strategic plan from 2023 to 2030 guides the initiative. It prioritizes interdisciplinary research, capacity building, and conservation efforts. The plan also focuses on ecosystem restoration and developing sustainable value chains. Equity and fairness remain central to all scientific activities.
