A comparison between an electric-powered Tesla Model 3 and a diesel Mercedes C220 shows that the emissions from the Tesla will be higher or much higher when you factor in how the electricity is produced in Germany and all indirect emissions that batteritillverkningen causes.
The German energy mix to reduce carbon from Tesla in the best of cases is somewhat higher than from the dieselbilen, in other cases higher or substantially higher particularly if the electricity comes from coal.
the Study from the Ifo Institute in Munich is made by Christoph Buchal, professor of physics at the university of Cologne, Hans-Dieter Karl, energy expert at the Ifo institute Hans-Werner Sinn, the former head of the Ifo institute and professor emeritus at the Ludwig-Maximilians university in Munich.
They believe that a more sustainable way is to bet on natural gas in internal combustion engines and then switch over to biogas and hydrogen.
– No, it is well known that the production of batteries for electric vehicles requires large amounts of energy. You add together the mining, enrichment and processing, there will be significant quantities of indirect emissions of greenhouse gases.
” Yes, but not nearly as much as elbilsbatterier. This means that the electric car as a new in bilhallen have a significant koldioxidskuld in the baggage compared with a petrol or diesel car. How big it becomes depends on a number of factors, not least how the electricity mix look like in the country in which the battery cells are manufactured.
– The German researchers have taken the average values for the batteritillverkningen and then count on the German electricity mix, which currently has a high proportion of brown – and hard coal. Then, emissions will be very high for Tesla and other batteribilar.
– Then, emissions will be near zero if one is only looking at the driving of the car. Electric car wins here, unlike in Germany. Weigh in batteritillverkningen it takes a few years of driving before the electric car will catch up and overtake the dieselbilen.
Even better it becomes, even if the battery cells, which is very energy intensive to produce, being built in Sweden. When will the electric car in a completely different position.
– No, the study applies to the German conditions today. The basis for calculating emissions from batteritillverkningen shows a large spread. New batterifabriker, like the one in Skellefteå, will give completely different values. The share of renewable in power generation is increasing in the world. The batteries are developed. All in all it will give batteribilen better conditions.
– the Electric car also has other advantages such as zero local emissions and less noise. It is up to four times more energy efficient than petrol engines. It is possible to fill up with locally produced energy. It breaks the dependency on oil.
To freeze an image of the current condition liable to cause errors. See eldriften in a long-term perspective, and adds to the recycling of end-of-life batteries and the ability to give the batteries a second life for energy storage, then improved the estimate even more.
– Yes they highlight natural gas as the bridge to a future with green methane and hydrogen. Already with fossil natural gas, emissions will be significantly lower than with diesel, they say.
– Vätgasspåret is very interesting as an alternative, or rather as a complement to battery operation. The electric drive with fuel cells and hydrogen is a technology which including Toyota very much believe in. The advantage is that the car can be refuelled in just 3-4 minutes, and the range is 40 to 50 miles. The drawbacks are that the infrastructure is not developed and the conversion efficiency is lower than with battery power.
the gothenburg-based Powercell, which develops and manufactures bränslecellsstatckar, has just signed a contract with German Bosch on a development and license agreement worth over a half billion crowns. Bosch, which is the world’s largest subcontractor to the automotive industry, see a big market emerging for hydrogen, particularly for heavy transport.
