 The findings show that the supply structure that needs to be built and its efficiency depend greatly on energy-consuming applications' load curves; it turns out that short fluctuations of a few days are less important((Author's note: Unlike what is frequently argued today, short-term storage is not the decisive issue here, since financially feasible technology is already available (pumped storage plants, etc.); it must "only" be expanded, and enough sites need to be found. The problem is, in fact, political, but it should be taken seriously, considering the prevailing attitude. Seasonal storage, which has also turned out to be essential (such storage has no location problems, since there is already sufficient storage used for natural gas), significantly increases costs for the applications that need it (heating, e.g.) because of high losses; this problem can also be solved (with improved efficiency).)), since medium-term grid storage (pumped storage, etc.) can generally balance them out. The situation is different when an application's demand has significant seasonal fluctuations, such as when heating drops to zero for several months at a time. Energy generated from primary power sources (wind turbines, etc.) then has nowhere to go – unless this excess power is sent to the P2G system and turned into methane. The requirement for complete supply is: \\ The findings show that the supply structure that needs to be built and its efficiency depend greatly on energy-consuming applications' load curves; it turns out that short fluctuations of a few days are less important((Author's note: Unlike what is frequently argued today, short-term storage is not the decisive issue here, since financially feasible technology is already available (pumped storage plants, etc.); it must "only" be expanded, and enough sites need to be found.
