G 220 (A)
Power-to-Gas Process Plants — Engineering, Manufacturing, Construction, Commissioning and Operation
Power-to-Gas Energieanlagen: Planung, Fertigung, Errichtung, Prüfung, Inbetriebnahme und Betrieb
Brief description
G 220 can be applied to power-to-gas energy systems that feed hydrogen into hydrogen networks. The DVGW Code of Practice also applies mutatis mutandis to power-to-gas energy systems that supply industry and commerce or feed into their own networks or pursue other H2/SNG end applications. This Code of Practice applies to the planning, manufacture, construction, testing, commissioning and operation of power-to-gas energy systems for the generation of gases in accordance with the German Energy Industry Act, which are fed into public gas supply networks with gases and/or gas mixtures in accordance with DVGW Code of Practice G 260 via feed-in systems in accordance with DVGW Code of Practice G 265-3. It can be applied mutatis mutandis to power-to-gas energy plants that feed hydrogen into hydrogen networks. It also applies mutatis mutandis to power-to-gas energy plants that supply industry and commerce or feed into their own networks or pursue other H2/SNG end applications. Synthetically produced methane (SNG) in accordance with this Code of Practice, which meets the material requirements of DVGW Code of Practice G 260, can also be fed in via systems in accordance with DVGW Code of Practice G 265-1. The limit of the scope of application of this worksheet can mark the transition to a feed-in plant, to H2/SNG end applications, to media supply or further utilization paths (e.g. oxygen or heat extraction). This limit can be synonymous with the application of further technical regulations, operator and ownership limits. It is therefore recommended that the transition or the limits of the area of application for gases and liquids be marked by shut-off valves, whereby the respective limit should be in the direction of flow downstream of the shut-off device.
