Compressed Natural Gas Energy Storage

Download the document.

Compressed natural gas energy storage (CNGES) is a faster and more cost-effective way to store and recover energy. It uses existing natural gas infrastructure to convert electrical energy from renewable sources to potential energy during off-peak periods, then back to electricity during peak demand. Clean energy powers existing compressors with new expander generators installed at pressure reduction stations in the gas transmission network. The operating pressure of the pipeline is managed in between the compressors and expanders using new control algorithms.

ISTC is performing a conceptual (Phase I) study, funded by the U.S. Department of Energy, at the University of Illinois Urbana-Champaign’s (UIUC) Abbott Power Plant and will integrate natural gas-based energy storage into its operations. The goal of the two-stage project is to demonstrate the technical and economic feasibility of integrating CNGES technology with an existing cogeneration fossil asset and establishing the path for its maturation and commercialization.
