Table 4 Technical biomethane potentials for 2030/2050 in relation to projected total EU gas demand (based on [5, 6, 12, 47, 83, 86,87,88])

From: How and to which extent can the gas sector contribute to a climate-neutral European energy system? A qualitative approach

Baldino et al. [6] 170 2803 6% 290 2752 11% Only sustainable feedstock considered
European Commission [83] 360 13% n.a n.a. Technological focus on digestion process, gasification out of scope
Mathiasson. (only digestion) [47] 300 11% n.a n.a. Technological focus on digestion process, gasification out of scope
Mathiasson (digestion and gasification) [47] 500 18% n.a n.a. Consideration of both digestion process and gasification technology
Scarlat et al. [5] 300 11% 510 19% Only residues and sewage sludge are considered; 2050 value represents full technical potential
Searle et al. [86] n.a. n.a 360 13% Only residues are considered
van Melle et al. [12] n.a. n.a 980 36% Incl. cover crops based on sequential cropping strategies
Kovacs et al. (without energy crops) [87] 340 12% 1030 37% Only residues are considered
Kovacs et al. (incl. limited energy crops) [87] 500 18% 1510 55% Additional scenario including most conservative energy crops potential
