Berlin, 24. October 2014 – no more fuel from the field. For more fuels from renewable energies. The ideal gas station of the year 2020 could look something like this: for the many cars in the fleet, there are mineral oil-based gasoline and diesel fuels. Without the addition of ethanol (e10, e5) or fatty acid methyl ester (b7), the dubious agro-fuel. Next to it, there is a hydrogen tank, which is not reformed from fossil natural gas, but produced on site by electrolysis with green electricity. And, of course, the cables will also supply several fast-charging stations for battery-electric cars of all standards.
An absurd vision? Not from a purely technical point of view. The reality will look much more nuchter, although an ordinance amendment to the federal immission control act (bimschg) passed last week creates the necessary leeway. Put simply, germany is already laying the groundwork for the national implementation of a biofuel quota law that will be changed by the eu at the beginning of 2015.
Review: with the use of so-called biofuels, the eu wanted to a) reduce dependence on imported crude oil and b) lower carbon dioxide emissions. The buck stopped with the mineral oil companies – it was and is up to them to decide how the specified quota was to be met. The unfortunate result is well known. The addition of ethanol to gasoline (up to ten percent by volume for e10, five percent for regular premium fuel) and fatty acid methyl ester ("fame" with a maximum of seven percent by volume, i.E. B7 for diesel fuel) met the standard. And indeed, agriculture got a boost. The debate about whether the competition between the tank and the plate is ethically correct still makes many drivers turn up their noses at biofuel. And whether co2 emissions have actually been reduced is uncertain.
Gruner hydrogen and electricity count toward quota
This is why the eu is changing its policy and is now demanding a verifiable reduction in co2 emissions of six percent by 2020 in addition to ten percent renewable energies in the transport sector.
This is where the revised bimschg comes into play. It allows hydrogen and electricity from renewable energies to be counted towards the eu quota. So there is a clear path for the energy turnaround on the road, because it is an indirect demand if the mineral oil companies no longer have to rely on the agro-fuels e5, e10 and b7, which are also quite unpopular there, in order to fulfill the eu obligation.
