The MoCEGS project has successfully performed research in various parts of energy circularity. On the macro-scale, the MoCEGS project has provided a large-scale data reconciliation algorithm, domain adaptation zero-shot learning in sequence (DAZLS) to allow high resolution energy data for energy planning. On the meso-scale, various retrofit algorithms were developed such as graph theory based retrofit algorithm, automation of P-graph framework, multi-period multi-objective graph theory planning, Shapley-Shubik based superstructure modelling etc. These fundamental development allows for advanced planning for the circular economy. Furthermore, a digital twin based on such fundamental understanding and the combination of graph theory development and high resolution energy data within EU27 (considering neighbouring countries was developed). This digital twin may assist policy making in high time resolution for energy and circularity in Europe. Furthermore, the MoCEGS project also explores some promising technologies at the micro-scale, this is a part of wider collaborative research efforts which includes co-pyrolysis technologies, waste oil technologies, single atom catalysts, etc.
