Unleashing the Flexibility of Gas: Innovating Gas Systems to Meet the Electricity System's Flexibility Requirements

The energy system is a complex network of physical infrastructure and markets interacting closely with one another. Within this network, the gas and electricity systems have become the backbone of modern energy production. Both systems are closely interconnected due to the vast deployment of efficient combined-cycle gas turbines (CCGTs) over the first decade of the 2000s, mainly in Organization for Economic Cooperation and Development countries. This increased interdependence and rapid penetration of variable renewable energy sources (varRE) make the gas-electricity nexus a primary concern and opportunity for energy system flexibility.
