“The proportion of biogas, gas from the fermentation of organic residues such as liquid manure, sewage sludge, organic waste or leftovers, is currently 26 million cubic meters, i.e. only 0.3 percent. Even if we can reduce gas demand with more energy efficiency and tap additional biogenic sources for generation, biomethane itself will by far not be able to meet the needs of industry for renewable gas, ”explains Pauritsch.
Gas lobbyist Mock disagrees and submits a study (here you can find the study) that considers a biogas potential of four billion cubic meters (50 percent of the current amount) to be feasible. The study authors state that this would only be possible if slaughterhouse waste was also included for fermentation, as well as much more domestic wood and even fertilizer.
Mock envisions a funding model that has been around for a long time with green electricity – gas customers pay for the funding through their gas bills.
The rest, says Mock, could be imported from biogas plants in the east and hydrogen from photovoltaic plants in the Sahara.
“Neo-colonialism” is what Hammer calls it. Austria pays eight billion euros a year for energy imports. Money that, in his opinion, could be better invested in Austria. “In addition, we will have to replace 85,000 oil boilers and gas boilers every year, so we need a lot more plumbers and production companies. This is a great opportunity in times of record unemployment. “
