6、the natural gas grid” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was DIN-Normenausschuss Gastechnik (DIN Standards Committee Gas Technology). This European Standard covers requirements and test methods for biomethane for injection in the natural gas grid. I

7、n Germany, the technical rule DVGW G 262 “The feed-in of gases from regenerative sources into the networks of public gas supply” governs the quality of biogases, including biomethane. DVGW G 262 will be revised upon publication of this European Standard to prevent any conflicts between the two docum

8、ents. However, DVGW G 262 will not be withdrawn because it covers other gases than biomethane, and through reference to DVGW G 260 “Gas quality” also includes calorimetric parameters which have not been dealt with in the present first edition of this European Standard due to a lack of agreement with

9、in Europe on this subject. In particular, there are no concrete details laid down in this standard regarding the Wobbe index range, which means that DVGW G 260 and DVGW G 262 continue to apply in Germany as regards natural gas and biomethane for injection in the natural gas grid until the next editi

10、on of this European Standard is published. It is intended to include this standard in the body of technical rules and standards for gas issued by the DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (German Technical and Scientific Association for Gas and Water). This is the first edition of thi

11、s standard.

28、opean Standard was prepared by CEN/TC 408 in response to the European Commission standardization mandate M/475. The Mandate asks for the development of a set of quality specifications for biomethane to be used as a fuel for vehicle engines and to be injected in natural gas pipelines (network). Howev

29、er, the scope of the standard was widened according to BT decision C109/2012 that redefined the scope of CEN/TC 408: “Standardization of specifications for natural gas and biomethane as vehicle fuel and of biomethane for injection in the natural gas grid, including any necessary related methods of a

30、nalysis and testing. Production process, source and the origin of the source are excluded”. NOTE The CEN Technical Board (CEN/BT) is responsible to coordinate the work between technical bodies in order to achieve a coherent set of standards and to avoid overlaps. One of the aims of European policy i

31、n the field of energy is to increase the security of energy supply in the EU as well as to contribute to reduce the emission of greenhouse gases accepted by the EU at Kyoto. In this context, a special focus is given to the development and use of energy from renewable sources. Directive 2009/28/EC on

32、 the promotion of the use of energy from renewable sources and amending and subsequently repealing Directives 2001/77/EC and 2003/30/EC stipulates clear aims regarding the percentage of renewables in EU energy consumption and states the related need to support the integration of energy from renewabl

33、e sources into the energy networks including the establishment of appropriate technical rules in line with Directive 2003/55/EC (Article 6) replaced by 2009/73/EC (Article 8) for the realization of the competitive single European Gas Market and the technical interoperability of gas networks, (networ

34、k connection, gas quality, gas odorization and gas pressure requirements). Supporting the EU policy and therefore the maximization of the production and use of biomethane and considering the absence of standards the European Commission DG ENER has included the injection of biomethane in natural gas

35、pipelines in Mandate M/475. Biomethane in this context can be produced from biological (fermentation, digestion ) and thermochemical processing of biomass and is appropriate to be used as a blending component to natural gas. A special focus is given to the development and use of energy from renewabl

36、e sources of biological and non-biological origin. Other gases complying with this standard can be injected. Figure 1 provides a visual representation of some applications of biomethane. Mandate M/475 indicates that the requirements for natural gas quality for injection in the natural gas network ar

37、e developed by CEN/TC 234 in answer to Mandate M/400 on natural gas quality. CEN/TC 408 should consider the work of the pending mandate M/400 on gas quality, and should refer to the parameters as defined and specified in EN 16726. This standard should exclude the definition of any parameters or subs

38、tances that are addressed in EN 16726. However, it may specify more strict limits for parameters or substances unique to biomethane if deemed technically necessary. If needed, additional parameters or substances should be defined. EN 16723-1:2016 (E) DIN EN 16723-1:2017-01 5 Key 1 biogas from digest
