A 250 kilowatt methane synthesis plant was constructed by the Center for Solar Energy and Hydrogen Research (ZSW) at Baden-Württemberg and the Fraunhofer Society in Germany and began operating in 2010. It is  being upgraded to 10 megawatts, scheduled for completion in autumn 2012.
The George Olah carbon dioxide recycling plant operated by Carbon Recycling International in Grindavík, Iceland, has been producing 2 million liters of methanol transportation fuel per year from flue exhaust of the Svartsengi Power Station since 2011. It has the capacity to produce 5 million liters per year.
Audi has constructed a carbon-neutral liquefied natural gas (LNG) plant in Werlte, Germany. The plant is intended to produce transportation fuel to offset LNG used in their A3 Sportback g-tron automobiles, and can keep 2,800 metric tons of CO out of the environment per year at its initial capacity.
Zero, a British-based company set up by former F1 engineer Paddy Lowe, has developed a process it terms petrosynthesis to develop synthetic fuels from atmospheric carbon dioxide and water using renewable energy. In 2022 it began work on a demonstration production plant at Bicester Heritage near Oxford.
Commercial developments are taking place in Columbia, South Carolina, Camarillo, California, and Darlington, England. A demonstration project in Berkeley, California, proposes synthesizing both fuels and food oils from recovered flue gases.
