2.5.2019 Stuttgart. Heat and energy from the own house: Porsche has two new CHP plants in Stuttgart-Zuffenhausen connected to the grid, thus expanding its environmentally-friendly energy mix, and closes the remaining gap to a CO2-neutral production of the fully electric Taycan at the traditional site in Zuffenhausen.
The about two megawatts of heat and power generator are operated exclusively with Biogas produced from biowaste and residues.
Unlike conventional power stations, CHP plants are used for the parallel production of heat and electricity. The energy production resulting waste heat is discharged as loss into the environment but used for Heating. Efficiency benefits can CHP play works then fine, if they are operated in the vicinity of a constant heat demand, for example in the vicinity of the paint shop, whose immersion baths and drying areas are in need of a steady process heat. Around 90 percent of the heat generated for the heating and hot water supply for the office and production building, in which on the Porsche site, nearly 12,000 people Zuffenhausen works. “The new CHP plants have an overall efficiency of more than 83 percent,” says Stephan Hartmann from the field of environmental and energy management at Porsche.
The two new cogeneration plants to Supplement the heat and electricity production, used for the Porsche so far, two natural gas-fired plants. So, these systems are converted to Biogas. In addition, Porsche is in Stuttgart, is prepared to use the bioenergy from urban bio-waste system as the city of Stuttgart takes your operational plant in 2021.
The capacity expansion of CHP units on the site of the Porsche plant in Zuffenhausen is associated with the build-up of production for the Taycan, the first fully-electric Porsche. The four-door electric sports car comes to the end of the year 2019 on the market and is produced at the Zuffenhausen plant is CO2-neutral. “Our goal is to not only produce emission-free car that is CO2-neutral, but to leave no ecological footprint. For this, we pursue the Vision of a ‘Zero Impact Factory’. The new block heating power stations are further important steps on this path,“ says Albrecht Reimold, Board member for production and logistics at Porsche.
