... efficiently accommodate temporal imbalances via their linepack. However, there is a downside to using linepack this way. Highly volatile production volumes of green hydrogen, caused by volatile wind and solar profiles, will result in frequent significant pressure fluctuations in the pipelines...

... pressure for each pipeline, and is known as linefill. Linepack is a quantity of gas in excess of linefill, which is necessary in order to make deliveries as requested and to provide operating tolerances, not least to cope with shutdowns upstream of the pipelines. A high linepack means higher pressure...
