and H gas in figures 12 and 13.Figure 12: Maximum range of permitted Wobbe index in Europe, L gasFrom the figure above it can be concluded that the permitted Wobbe values for L gas in Europeancountries all lie within the limits stated in EN 437. Only the German L gas may vary outside thelimits set by EN 437. Unpurified biogas with 60% methane has a Wobbe index of 24.6 MJ/m 3 andpurified biogas with 90% methane has a Wobbe index of 44,4 MJ/m 3 . Purified biogas thereforecould be used directly in the L gas grid in the Netherlands, providing other purity demands arefulfilled.page: 63
Figure 13: Maximum range of permitted Wobbe index in Europe, H gasThe allowed H gas compositions vary between different countries, some countries followthe recommendations in DVGW 260 and some the EN 437 (with minor variations).The actual gas compositions in the European countries, compared to EN 437 and DVGW 260 arepresented in figures 14 and 15.Figure 14: Maximum range of delivered Wobbe index in Europe, L gaspage: 64
