Scientists Discover A New Method To Generate Renewable Fuel That Could Change The World. The Technology Uses Solar Energy To Replicate The Photosynthesis Process.
Researchers from the University of Cambridge, located in the United Kingdom, developed technology that can recreate the photosynthesis process to convert carbon dioxide and water into fuel. The highlight of the research is that the renewable fuel can be used as fuel for vehicles already on the market.
With countries around the world seeking a way to move away from fossil fuels, electric forms of transportation are being promoted while discouraging the sale of vehicles with internal combustion engines (ICE).
Renewable Fuel Technology Can Prolong Vehicle Lifespan
Despite the policy having the right intention, a mandatory shift to electric cars will leave millions of combustion vehicles in scrap yards, while also increasing the demand for rare earth minerals needed to produce electric car batteries.

If you look at the sky this Wednesday, you will see the Pink Moon shining at its peak at 10:11 PM, but before you get disappointed, know that the name has nothing to do with the color and instead refers to flowers that bloom at this time in the United States.
A renewable fuel like this, produced with solar energy, that is carbon-neutral could extend the lifespan of ICE vehicles without raising concerns about environmental damage. The technology research being done at Cambridge promises to make this possibility a reality in the near future.
Biofuels, such as ethanol, have been suggested as substitutes for fossil fuels. Countries have already begun to use them as substitutes in smaller proportions. However, the production of biofuels requires the diversion of agricultural land.
With global production continually advancing, many question the need to turn food into renewable fuel. In the U.S. alone, 45% of the corn grown is used for ethanol production.
Erwin Reisner and his team of researchers from Cambridge have been looking for alternatives to generate zero-carbon fuels and found the answer in artificial leaves. Just like their natural counterparts, artificial leaves convert CO2 and water into usable chemicals through solar energy, which can be of great help in the pharmaceutical, fuel, or plastics industries.
Understand How The New Technology Works
The researchers were able to use their solar energy artificial leaf to generate syngas, a combination of hydrogen and carbon monoxide. However, they needed to generate much more complex chemicals in a single step for the technology to have technical applications.
Thus, the researchers then created a catalyst using copper and palladium that made it possible for the artificial leaf to generate complex chemicals such as propanol and ethanol. Both multi-carbon alcohols are also high-density fuels that can be easily stored and transported.
Research from other groups has also led to the synthesis of these alcohol molecules; however, the energy source in this case was electricity. This is the first time that only solar energy has been used to generate renewable fuel.
The technology is still in the proof of concept stage. The research team is now working to optimize light absorbers and the catalyst so that more fuel can be produced, increasing the overall efficiency of the solar energy system. Future work also involves scaling up the size of the leaf so that large volumes of fuel can be generated at once.
Advantages of Solar Energy
Solar energy produces no pollution, is clean, silent, renewable, and can be used in remote areas of the electrical grid, requiring minimal maintenance. Furthermore, the source has a low environmental impact, making it one of the most sustainable in the world.
Its operation, regardless of the project, is quiet and discreet, avoiding the generation of unpleasant noise and contributing to the reduction of noise pollution. Every day, new projects and technologies using this source are emerging around the world.
