The Dresden energy technology corporation sunfire is Audi’s project partner and the plant operator. It operates according to the power‑to‑liquid (PtL) principle and uses green power to produce a liquid fuel. The only raw materials needed are water and carbon dioxide. The CO2 used is currently supplied by a biogas facility. In addition, initially a portion of the CO2 needed is extracted from the ambient air by means of direct air capturing, a technology of Audi’s Zurich‑based partner Climeworks.

    Better living through chemistry? Technology will provide solutions and I am all for them as long as they are practical and the market adopts them without government force. I'm still waiting for my flying car. Why can't we scale up these little multi-prop drones we see everywhere?

    Pretty cool process. The chemistry is pretty basic but to make it an efficient process is the trick. I'm wondering why they are using high temp to separate the O and the H2 but if they need the high temperature to combine the H2 with the CO2 and they are using the same heat then that might make sense. Otherwise, it would seem to me that electrolysis would be a more efficient way to use solar electricity to separate the water.
