Rooftop Solar Refinery Produces Carbon-Neutral Fuels

Scientists in Switzerland have demonstrated a technology that can produce kerosene and methanol from solar energy and air

Scientists have searched for a sustainable aviation fuel for decades. Now, with emissions from air traffic increasing faster than carbon-offset technologies can mitigate them, environmentalists worry that even with new fuel-efficient technologies and operations, emissions from the aviation sector could double by 2050.

But what if, by 2050, all fossil-derived jet fuel could be replaced by a carbon-neutral one made from sunlight and air?

In June, researchers at the Swiss Federal Institute of Technology (ETH) in Zurich demonstrated a new technology that creates liquid hydrocarbon fuels from thin air—literally. A solar mini-refinery—in this case, installed on the roof of ETH’s Machine Laboratory—concentrates sunlight to create a high-temperature (1,500 degrees C) environment inside the solar thermochemical reactor.
