LNG–Air Mixture as a Supplementary Energy Injection into a Biogas Distribution Network

Biogas production efficiency fluctuates with climate variations and agricultural arrangements, which pose a limiting factor upon its single supply to end users via a regional exclusive network, especially in peak demand. In this paper, an appropriate methodology to address the contradiction between...
