Scientists develop carbon-neutral aviation fuel: Researchers in Switzerland have created sustainable, carbon-neutral versions of diesel and aviation fuel using just three inputs: carbon dioxide, water, and sunshine. This is the first time fuel has create outside a laboratory, in a power generator.
In 2017, the team began scaling up their idea and constructed a solar fuel manufacturing facility at the IMDEA Energy Institute in Spain.
According to studies, according to Newsweek, solar-produced kerosene, or jet fuel, is entirely compatible with how energy store, distributed, and utilized in an airplane’s engine. According to scientists, it may also mix with kerosene from fossil sources.
The manufacturing facility in Madrid, they said, is made up of 169 sun-tracking reflecting panels that focus and redirect solar energy into a solar reactor atop a tower.

Then, in the solar reactor, which has a porous structure constructed of the heavy white or yellow powder ceria, the concentrated solar energy drives oxidation-reduction (redox) reaction cycles.
The ceria then produces syngas, composed of hydrogen and carbon monoxide. From the water and carbon dioxide that was first pumped into the reactor. After passing through a gas-to-liquid converter, the syngas convert into liquid hydrocarbon fuels like kerosene and diesel.
According to the source, research co-author Professor Aldo Steinfeld remarked, “We are the first to show the whole thermochemical process chain from water and CO2 to kerosene in a fully-integrated solar tower system.”
He said that we’ve shown using solar technology that synthetic kerosene can make from CO2 and water rather than from fossil fuels.
According to reports, around 5% of today’s emissions come from aircraft. This is because kerosene or jet fuel, both liquid hydrocarbon fuels derived from crude oil, use in their engines.
There isn’t a safe or efficient method to fly an aircraft today. So creating carbon-free aviation fuels is now a primary worldwide energy concern.
