Lowe is the founder and CEO of the carbon-neutral synthetic fuel concern, whose early investors include 1996 world champion Damon Hill.
Sauber uses Shell fuel and lubricants but is free to sell sponsorship to other companies in the sector. As previously reported it has concluded a deal with US brand Sunoco for the three American races.
Zero will feature on the Swiss cars at all other events for the next two years, prior to the switch to Audi identity in 2026.
Lowe was last involved in F1 as chief technical officer of Williams, leaving the job in early 2019.
“We're here mainly to just bring the message about synthetic fuel technology, and how exciting it is," Lowe told Autosport. “So of course, we look to 2026, which will be a year of bringing in 100% sustainable fuels, and those can be either second-generation biofuels or synthetic fuels.
“So we're all about synthetics, it's an incredibly exciting element for the future of F1, and the world as a whole.”
Lowe believes that synthetic fuels will have an important role to play globally in the future.
