Content of DVGW Code of Practice G 100 DVGW Code of Practice G 100 serves as a basis for assessing the competence of technical experts for inspecting the technical safety of energy systems for gas and hydrogen supply. It specifies qualification requirements for technical experts for energy systems for the pipeline-bound supply of gas and hydrogen to the general public. In the course of converting the gas infrastructure to hydrogen in accordance with DVGW Code of Practice G 260, technical experts have a special role to play. The qualification requirements described in this DVGW Code of Practice G 100 form the basis for the inspections to be carried out in this context. This includes, in particular,the continuous training of the technical experts in relation to the developing state of the art. G 100 describes the qualification requirements for technical experts who inspect and assess the technical safety of gas supply energy systems on the basis of the Energy Industry Act (Energiewirtschaftsgesetz - EnWG) in accordance with the requirements of GasHDrLtgV and the DVGW Set of Rules. The person commissioning the inspection is responsible for selecting a suitable technical expert for the inspection task in question. When commissioning a certified technical expert, the qualification for the relevant technical field can be verified by a valid certificate from a certification body accredited in accordance with GasHDrLtgV or official recognition in accordance with GasHDrLtgV. When commissioning an inspection body, the inspection body is responsible for selecting technical experts qualified for the respective inspection task. The technical expert is also responsible for checking whether his qualifications are sufficient for the inspection task. This Code of Practice G 100 can serve as a basis for this. DVGW Code of Practice G 100 ensures that the legal and technical framework conditions are mastered, only well-trained persons are recognised as technical experts, the technical experts have a practical connection to their area of specialisation, have sound knowledge and experience in the respective area of expertise, the specialised knowledge can be applied to specific issues in the subject area, the tasks, possibilities and discretionary scope of the technical experts can be recognised, used andfilled. The following amendments have been made compared to DVGW Code of Practice G 100:2015-10: The normative references have been adapted to the current status of the DVGW Set of Rules. The term energy facility was adapted due to the planned expansion of the term “Energy” to includehydrogen in the Energy Industry Act in order to clarify that this Code of Practice also applies to hydrogennetworks. The designation of Area of Expertise VIb has been adapted to the contents of the 2020 edition ofDVGW Code of Practice G 472. Notice has been included in the description of the areas of expertise that the technical experts inaccordance with this Code of Practice fulfil the qualification requirements for a person qualified toperform inspections in accordance with the German Industrial Safety and Health Ordinance(Betriebssicherheitsverordnung - BetrSichV) for testing the explosion safety of systems in their respectivearea of expertise. A corresponding explanation has been included in the foreword. In clauses 6.4.2.2, 6.4.2.3, 6.4.2.5 and 6.4.3.8, the term "explosion protection" has been replaced by"explosion safety" in order to establish the reference to the test object in accordance with IndustrialSafety and Health Ordinance (BetrSichV). For area of expertise IX, the required level of qualification was compared with the requirements of DINEN ISO 15257, which has replaced DIN EN 15257. In clause 6.5.1, references to the explosion safety testing for FG II, III, V and VIII have been added asa prerequisite for initial recognition. In Annex A, the listed Technical Rules have been adapted to the current status of Set of Rules andexpanded to include the technical rules on hydrogen systems.

Content of DVGW Code of Practice G 1030 DVGW Code of Practice G 1030 sets out the requirements for the operators of stations for the production, transport, upgrading, conditioning or injection of biogas, irrespective of the ownership structure and organisational form, with regard to the structural and process organisation. Sufficient qualification and organisation of the operators is a prerequisite for ensuring the planning, construction, operation and maintenance of the respective biogas stations, also in compliance with safety and environmental regulations. G 1030 specifies the requirements of the Energy Industry Act (EnWG) for the qualification and organisation of operators of plants for the production, storage, transmission, upgrading, conditioning or injection of biogas or biomethane. According to the EnWG, this also includes hydrogen from renewable sources. DVGW Code of Practice G 1030 has been extensively revised, restructured and changes have been madein almost every section. Only major new topics are therefore listed below. Compared to DVGW Code ofPractice G 1030:2010-12, the following changes have been made in particular: Inclusion of hydrogen from renewable sources in the scope of application in accordance with theEnWG Inclusion of power-to-gas energy systems in the scope of application in accordance with DVGWCode of Practice G 220 Definition of power-to-gas energy plants, hydrogen feed-in plants, biogas and biomethane, contractualpartners (incl. operators, service providers, cooperation partners) Integration of biogas conditioning system into biogas feed-in plant Table of contents Foreword Authors 1 Scope 2 Normative references 3 Terms, symbols, units and abbreviations 4 Basic requirements 5 Tasks and fields of activity 6 Organisation 7 Personnel 8 Contractual partner 9 Technical equipment Important normative references DVGW Code of Practice G 213DVGW Code of Practice G 260DVGW Code of Practice G 415DVGW Code of Practice G 492DVGW Code of Practice G 495 German version DVGW-Arbeitsblatt G 1030   Buy DVGW Code of Practice G 1030 You can purchase DVGW Code of Practice G 1030 as PDF file for immediate download. 

Content of DVGW Information GAS No. 29 This DVGW Information GAS No. 29 provides an overview of the requirements that must be met for the use of hydrogen in systems for the pipeline-bound supply of the general public and the connected gas applications so that these can be labelled "H2-ready".  In this DVGW Information GAS No. 29, a model is proposed to visualise the different levels of assessment in order to classify statements on the readiness of infrastructures for the grid-based supply of hydrogen. The term "H2-ready" is used to describe this readiness for hydrogen use, which is explained in the respective context in this DVGW Information GAS No. 29.  The proposed model can also be applied analogously to new or existing plants for operational self-supply in which hydrogen is to be used, taking into account the specific legal requirements.  Safe operation with the hazardous substance natural gas is already guaranteed for gas supply networks and gas applications. If a natural gas network is converted into a hydrogen network, the same level of safety can be guaranteed if the DVGW Codes of Practice applicable to hydrogen are taken into account - without prejudice to other legal requirements.

This DVGW-Information GAS No. 17 provides information on how to implement the lightning protection requirements in accordance with IEC 62305 for systems of gas and hydrogen transport and distribution systemas well as for systems supplying commercial, industrial or comparable facilities. Lightning protection measures are used to protect people, structures and technical equipment against the effects of lightning.

This standard G 493-2 encompasses personal and professional requirements for companies providing maintenance for gas plants and installations that fall within the scope of DVGW G 495 (A), as well as biogas injection and refeeding plants as specified by DVGW G 265-2 or hydrogen injection plants as specified by DVGW G 265-4 (M).Companies which, within the context of comprehensive plant management, either as original operators or as contractors, are responsible for the maintenance of energy plants, and possess the required personal qualification and organization according to DVGW G 1000 (A), may conduct the maintenance of gas plants without certification as defined by this standard within the network which they have the abovementioned responsibility for. The prerequisite for the maintenance without certification as mentioned above is that the expert and tech-nical conditions detailed in this standard are met by the company’s own workforce or by service providers with a TSM certification or other corresponding certifications. The company shall appoint the experts re-sponsible for maintenance in writing. The fulfilment of these conditions can be verified e.g. during a TSM review according to DVGW G 1000 (A).

This Technical Rule G 260 specifies the requirements for the quality of fuel gases used in the supply of the general public with gas and sets the parameters for gas delivery, gas transportation, gas distribution, gas storage, operation of gas plants/systems and gas appliances for commercial and industrial gas applications as well as for development, standardization, and testing. Gases transported in separate pipelines which are not used in the supply of the general public, or are used as energy carrier or resource, and/or are used in special gas appliances are not subject to the scope of this Technical Rule.

The regulations in this Guideline G 451 shall be observed when planning and constructing gas transmission pipelines in conjunction with statutory procedures such as regional planning procedures und planning permission hearings.

This Standard shall also apply, mutatis mutandis, to gas mixing plants that supply process gas to trade and industry and to industrial gas mixing plants for in‑house mixed‑gas supply.Gas mixing plants are frequently integrated into gas measurement and pressure reduction stations, which latter shall meet the specifications of DVGW Standards G 491 and G 492. In other words, most of the requirements specified in these Standards will also apply to gas mixing plants. All other requirements that go beyond the scope of G 491 and G 492 are described in this Technical Rule at hand, which first and foremost complements DVGW Standard G 491.

This DVGW Standard can be used as a guideline as it summarises the minimum requirements specified in the DVGW Sets of Rules that shall be observed by design firms, specialist contractors, operators and the involved authorities during the design, construction and operation of gas pipework for the transmission of untreated or partially treated biogas. The clause on Design also draws attention to the fact that the pertinent approvals and / or permissions shall be obtained prior to the start of construction of pipework planned to cross e. g. water bodies, roads and railways.Gases produced by fermentation processes such as e. g. biogases obtained from agriculture that are generally used to meet internal requirements and / or to power decentralised systems such as e. g. combined heat and power plants, are untreated or partially treated biogases that are not considered gases in accordance with DVGW Standard G 260.Nonetheless, the documents that form part of the DVGW Set of Rules that are referred to in this Standard shall also be applied to pipelines that transmit untreated or partially treated biogas.
