One specific innovation is altering how technology interacts with nature.
The early global transition focused on clean energy, but the world is now entering a new frontier with clean fuels.
This Cambridge-developed innovation aims to improve the shipping and aviation sectors by “bottling” renewable energy with the smallest possible impact.
By mimicking photosynthesis to produce a useful, clean fuel product, could we be one step closer to a carbon-neutral future?
How a decade-long chase for clean fuels came to a revelation
For too long, the world has been trapped within the shackles of fossil fuels. In desperation to finally break free, the hard-to-abate sectors have been seeking clean fuels.
The pursuit has lasted many years, but in the end it has always come to a choice between two compromises.
Biofuels offer a clear, circular path to freedom from fossil fuels. However, land use and food security always lead to heated debates.
Green ammonia has the potential to power the high seas, yet the risk of extreme toxicity is too great.
Electric transport is conquering the roads, but global trade is far from being powered by current battery technology.
Scientists began to realize that it is impossible to force nature to submit to industrial solutions.
Fortunately, an innovative device shows that there is no need to try to “outperform” nature.
Instead, it can be used to shrink nature’s most complex process.
The need to shrink an invisible crisis
Air pollution may be invisible to the naked eye, but its impact is as clear as day.
Some cities do still face the visible consequences of the fossil fuel era, but many are taking action.
India installed multi-purpose “liquid trees” to clear urban air. However, this solution is merely a drop in the ocean, as emissions from ships and flights are abundant and disruptive.
Carbon dioxide emissions are reaching historic concentrations, inevitably destabilizing the global climate one flight and ship at a time.
The call for clean fuels within these sectors is now greater than ever.
However, instead of reinventing engines and the current infrastructure to benefit from clean fuels, the fuels themselves are being adapted.
Some companies, such as Moeve, are already moving forward with renewable diesel and sustainable aviation fuel complexes.
In an even more pioneering move, scientists from the University of Cambridge have created a device that mimics photosynthesis.
Mimicking photosynthesis: The result is “breathing carbon”
The research team, led by Professor Erwin Reisner, reimagined carbon capture and storage (CCS) by changing how carbon is stored.
The team realized that, instead of storing captured carbon underground, it could be converted into a useful product.
This led to the creation of the photosynthesis-mimicking device called the “solar-powered reactor.”
A 24-hour cycle of clean fuel
The reactor captures carbon dioxide from the atmosphere at night. During the day, mirror-concentrated solar power is used to change the captured carbon into syngas.
The next step for the research team is to develop a method to transform the solar syngas into liquid fuels. These fuels will then be used to power the hard-to-abate sectors.
“Instead of continuing to dig up and burn fossil fuels to produce the products we have come to rely on, we can get all the CO2 we need directly from the air and reuse it.” – Reisner
The Cambridge solar-powered reactor shows the world what can be achieved when technology works with nature instead of against it.
This high-tech engineering not only pushed the boundaries of traditional carbon storage but also created a high-density industrial asset.
Bridging the gap between global transportation and microscoping photosynthesis could finally end the fossil fuel era.
The heart of America has already invested in a true pollution harvester; is the rest of the world next?
