Scientists have developed a process using sunlight and air to create carbon-neutral jet fuel.
The process could sustainably fuel planes, ships and road haulage.
Sustainable aviation fuels are a key part of the industry’s plans to decarbonize.
Scientists have developed a way to make carbon-neutral jet fuel for hard-to-electrify heavy transport using sunlight and air.
The fuels release as much carbon dioxide (CO2) when combusted as they absorb from the atmosphere when produced, so no additional CO2 emissions are generated.
The new process could further efforts to combat climate change by decarbonizing transport sectors like aviation, which is responsible for almost 3% of all human-made carbon dioxide emmissions, shipping and road haulage.
Researchers, led by Aldo Steinfeld, Professor of Renewable Energy Sources at ETH Zurich, have developed an industrial plant that extracts carbon dioxide (CO2) and water from the air. Solar energy is then used to split these compounds and produce syngas - a mixture of hydrogen and carbon monoxide. This is then further processed to create kerosene and methanol which can be used as a substitute for traditional fuels.
