Crowd oil—fuels from air-conditioning systems

Researchers at the Karlsruhe Institute of Technology (KIT) and the University of Toronto have proposed a method enabling air conditioning and ventilation systems to produce synthetic fuels from carbon dioxide (CO2) and water from the ambient air. Compact plants are to separate CO2 from the ambient air directly in buildings and produce synthetic hydrocarbons which can then be used as renewable synthetic oil. The team now presents this “crowd oil” concept in Nature Communications.

To prevent the disastrous effects of global climate change, man-made greenhouse gas emissions must be reduced to zero over the next three decades. This is clear from the current special report of the Intergovernmental Panel on Climate Change (IPCC). The necessary transformation poses a huge challenge to the global community: Entire sectors such as power generation, mobility and building management must be redesigned. In any future climate-friendly energy system, synthetic energy sources could represent an essential building block. “If we use renewable wind and solar power as well as carbon dioxide directly from the ambient air to produce fuels, large amounts of greenhouse gas emissions can be avoided,” says Professor Roland Dittmeyer from the Institute for Micro Process Engineering (IMVT) at KIT.
