Polygeneration, the generation of energy and resources by a number of interrelated systems, offers a series of benefits for local communities. Energy systems are typically mis-matched to energy demand. China, for example, has seen massive growth in its population and economy with rural urban migration receiving significant attention. The combination of population growth and the draw of the city mean that rural communities in the outlying regions near city conurbations are actually at record levels. Supplies of water through watersheds require careful stewarding and management. This project involving Imperial College London and Tsinghua University in collaboration with the Beijing Water Authority has explored the techno-economics, system design and options for implementation of an integrated polygeneration system for watershed communities in rural areas supporting urban conurbations. Polygeneration technologies explored include hybrid solar thermal and voltaic systems, water purification, thermal accumulators and chilling systems. Options for four villages were explored as a result of the collaborative exchanges and design solutions for these developed. The four villages in the Badaling region of Beijing, considered were: Babaotang village; Caijiadian village; Dongcaoying village; Dongsangyuan village.
