Abstract: Comparison and analysis are carried out on current gas peak shaving techniques at home and abroad. The paper describes technical advantages of NGH and summarizes structural characteristic of NGH, gas storage performance and processes in its manufacture, storage and gasification.Analysis method is adopted to research the usable pressure energy of gas networks and recovery and utilization technological process for the pressure energy are presented.It is considered that combining process cold energy produced during high—pressure gas peaking with NGH manufacture process can promote effective generation of NGH, simplify manufacture equipments of NGH and multiply utilization manners of cold energy.
