The research will create a hybrid anaerobic digestion process in which hydrogen made from renewable energy sources (e.g. wind and photovoltaics) is used to produce biomethane at more than 95% purity. The process therefore provides an efficient in situ biogas upgrading technique which will maximise the conversion of the available carbon in waste biomass into a fuel product that has a wide range of applications, including short-term storage for grid balancing and use as a vehicle fuel. The process is likely to be more environmentally friendly and sustainable than current methods for biogas upgrading as there is reduced process loss of methane. The target is to develop the system for use in the water industry where there is a large potential to integrate it into existing infrastructure and to maximise the use of process heat and other by-products. A second targeted application is at a smaller scale on farms, where there is an abundant supply of waste biomass and a lack of suitable biogas upgrading plant.

该研究将创建一个混合厌氧消化过程，其中由可再生能源（例如风能和光能）制成的氢气用于生产纯度超过95%的生物甲烷。因此，该方法提供了一种有效的原位生物气升级技术，其将最大限度地将废弃生物质中的可用碳转化为具有广泛应用的燃料产品，包括用于电网平衡的短期储存和用作车辆燃料。这一过程可能比目前的沼气升级方法更环保和可持续，因为甲烷的过程损失减少。目标是开发用于水行业的系统，其中有很大的潜力将其集成到现有的基础设施中，并最大限度地利用过程热量和其他副产品。第二个有针对性的应用是规模较小的农场，那里有大量的废弃生物质供应，缺乏合适的沼气提质工厂。
