Henrik Andersen, Consultant, Danish District Heating Association, comments in today´s issue of Børsen:

Is it not really unambitious to focus exclusively on biogas replacing natural gas? When we know that coal is much more pollutive than natural gas? Should we not instead test whether we could use biogas in the large central power plants, which today we are using tons of coal to produce electricity. For would it not be more ambitious to allow biogas to be used, where you get maximum power of this biomass. As it is today, expansion of biogas is non existing, even though the politicians the last few years have suggested that there should be built between 50 and 100 new plants. There are just not built any, because it is apparently not attractive enough to build them. Therefore manure from agriculture still lleads enormous quantities of methane gas straight up into thin air. Methane gas, which could have been used constructively in the energy sector and thus we could have avoided these emissions. Of course there are challenges when using biogas in the large central power plants. But not higher than they can be resolved. We have great experience with digging down natural gas pipelines. And it is simpler to operate  pumping and pipeline facilities than an upgrade installation.
So should we not increase ambitions and go replacing the worst pollution source rather than the second worst?
