This report documents the key results from the DOE Controlled Hydrogen Fleet and Infrastructure Validation and Demonstration project. This project is also referred to as the fuel cell vehicle and infrastructure learning demonstration.

Power system characteristics that mitigate and accommodate variability make it easier to integrate wind into grid operations. Wind-friendly physical characteristics include geographically and electrically large balancing areas, as well as generator characteristics such as fast-ramping, load-following capability. They also include generation and transmission market structures that provide access to conventional generation flexibility and maneuverability;...
