At full throttle towards "net zero"
According to the Federal Council, greenhouse gas emissions need to be reduced to zero net by 2050. To achieve this goal, motorized road traffic will have to undergo fundamental changes. Avenir Suisse has investigated which technical, economic and political measures need to be implemented to reduce CO2 emissions as efficiently as possible. The think tank was supported in this effort by Peter Richner, Deputy Director of Empa, and Christian Bach, Head of the Automotive Powertrain Technologies Laboratory.
In their contributions, both of them point out that focusing on a specific drive technology cannot be the solution. Rather, mobility must be viewed in the context of the entire energy system. The expansion of renewable energy sources automatically leads to a strong fluctuation in energy production: renewable electricity is not always generated where and when it is needed. There are peaks that put a strain on the grid, and it needs storage so that the energy is not lost. Mobility can support the overall energy system by converting excess electricity into fuels and thus enabling its use – in the form of hydrogen or so-called synfuels, synthetic substitute fuels for gas, diesel and petrol vehicles. At Empa, this technology-neutral approach is being demonstrated, for example, in the mobility demonstrator "move", where not only electric vehicles but also hydrogen and gas vehicles can fill up with renewable fuels.
