Where passion meets responsibility
How to successfully combine a passion for driving with caring for the climate? Porsche provides a twofold answer in the Taycan and Taycan Cross Turismo, and has also set up a charging infrastructure specifically for these electric sports cars. Drivers in search of a recharging point can use the “green electricity” filter to display a selection of matching charging stations, which they can then access via the Porsche charging service. This ensures that all their charging activities are carbon-neutral, which means climate-friendly motoring throughout the vehicle’s service life.
Porsche is focused on climate action in production, too: In Stuttgart-Zuffenhausen, the newly built production facility for these models is on its way to achieving almost zero environmental impact – among other things, with an energy supply for the site using renewable energy. Other climate-friendly features include the streamlined aerodynamics at the front of each car, complete with automatically controlled air intakes that cut energy consumption and increase range. Some of the materials in the e-sportsters’ interiors are sourced from secondary raw materials. And as the perfect accessories for a climate-friendly “last mile”, Porsche offers two different e-bikes plus a new, specially designed rear carrier.
Taycan Turbo S Cross Turismo - combined power consumption in kWh/100 km: 29.4; CO₂ emissions in g/km: 0; efficiency class: A+
Taycan 4S Cross Turismo - combined power consumption in kWh/100 km: 28.1; CO₂ emissions in g/km: 0; efficiency class: A+
Fast progress on the road to becoming a zero-impact factory
Speed is in Porsche’s DNA. So it’s no surprise that the sportscar manufacturer’s main plant in Stuttgart-Zuffenhausen, Germany, is racing towards its goal of becoming a zero-impact factory – one that will have no negative effects on the environment. CO₂ emissions from vehicle production at this plant have fallen by over 90 percent since 2014. At the same time, energy consumption has fallen by more than 25 percent. The Zuffenhausen plant has been producing Porsche’s all-electric Taycan sportscar in a net carbon-neutral process since the end of 2019, using only energy from renewable sources. The company is also making it easy for employees to help protect the climate, with an app for setting up carpools and the Porsche JobRad program for leasing company bicycles. Porsche also subsidizes season tickets for local public transit services.
Climate action made in Leipzig
All the electricity required for Porsche’s production operations in Leipzig is generated from renewable energy, some of it from the factory’s own rooftop photovoltaic system. A biomass-fired combined heat and power plant located right next to the factory meets up to 80 % of the energy requirements of both paint shop and assembly line – and does so in a carbon-neutral manner.
The Leipzig plant saves a great deal of energy and conserves resources at many different points in the production process. In the paint shop, for example, a stone dust-based separation process filters the inevitable excess paint particles from the overspray. Compared to water-based systems, this dry process is up to 60 percent more energy-efficient. Opting for low-energy LEDs instead of fluorescent lamps for making visual inspections in the light tunnel has cut the energy required by 50 %. And automated shuttle technology in the small parts store cuts emissions by around 675 metric tonnes of CO₂ a year compared to a conventional warehouse.
Another focal point is the body shop. Here, robots join panels using flow-drilling screws. According to this ingenious, waste-saving method, the screws are inserted with no need to drill holes in advance. The servo-pneumatic processing of many components in the body shop no longer requires any energy-intensive compressed air at all. And in the Macan body shop, an innovative cooling system for robot welding tongs, complete with integral heat recovery, cuts energy consumption by more than 365,000 kWh per year.
The Leipzig plant is currently preparing to produce the next-generation Macan with an all-electric driveline. At the same time, Porsche is investing in the expansion of the charging infrastructure. Since February 2020, twelve 350 kW (DC) fast charging points and four 22 kW (AC) charging points have been available at the Leipzig plant – round the clock, seven days a week, for all makes of vehicle. The total capacity of the charging park, including six fast charging points for company use, amounts to 7 MW. This makes it one of Europe’s most powerful fast charging parks operating entirely on green electricity.
Climate-friendly energy for the Taycan
Porsche generates the energy for a carbon-neutral production of the fully electric Taycan at its plant in Zuffenhausen using systems such as cogeneration plants. Unlike conventional power stations, cogeneration plants simultaneously generate heat and electricity. The heat created by the energy production is not dissipated into the surrounding environment as waste but rather used for heating. The unique aspect is that the approximately 2-megawatt heat and electricity generators our run entirely on biogas made from organic waste and residual materials.
Roughly 55 litres of diesel or petrol per minute flow through the filling nozzle when refuelling. That is why it only takes around one minute to fully refuel a mid-size vehicle. “Refuelling” electric vehicle could soon be almost as fast. The FastCharge research project has presented ultra-fast charging stations with similar capabilities. A Porsche research vehicle with a net battery capacity of around 90 kWh achieved charging times of less than three minutes for the first 100 km of range at a charging power of over 400 kW.
The FastCharge research project investigating the technical prerequisites for vehicles and infrastructure that need to be achieved to enable extremely high charging performance. Depending on the vehicle model, the new and free of charge ultrafast charging station can be used for vehicles with both 400 V and 800 V battery systems. The charging performance provided automatically adjusts to match the vehicle’s maximum permissible charging power.
Elegant climate protection
The Porsche Centre in Berlin-Adlershof has an especially aesthetic approach to generating climate-friendly solar electricity: a 25 m high photovoltaic pylon. The convex façade covering roughly 270 square metres generates up to 30,000 kWh of solar electricity per year using 7,776 solar cells. The electricity generated is not only used for the Porsche Centre itself. Visitors can also recharge their electric vehicles at Porsche free of charge.
