Optimum use of sustainable gases by expanding the distribution band of gas quality

Compared to the small gas distribution band, to what extent would an expanded range of Wobbe Index for natural gases facilitate the integration of sustainable gases, namely the performance of end-use equipment?

Following the same approach as used in project ‘Effects of sustainable gases on end-use equipment within the current distribution bands’ (A13), this project characterizes the effects of supplying sustainable gases via the natural gas infrastructure on the behavior of the major classes of end-use equipment in the Netherlands: domestic and commercial, large-scale and industrial, and for power generation. The emphasis of this research will be on what can be referred to as critical issues, related mainly to safety, such as flame lift, flashback, carbon oxide (CO) emissions, engine knock, and unwanted ignition and instability in turbines. Nevertheless, important issues regarding changes in the emissions of nitrogen oxides (NOx) and efficiency will also be examined during the natural course of the project. The degree to which widening the range of natural gases also widens the range of acceptable sustainable gas compositions and/or mixtures of sustainable gases with natural gases will be investigated.
