Researchers have developed a system that can transform plastic waste and greenhouse gases into sustainable fuels and other valuable products – using just the energy from the Sun.

The researchers, from the University of Cambridge, developed the system, which can convert two waste streams into two chemical products at the same time – the first time this has been achieved in a solar-powered reactor.

The reactor converts the carbon dioxide (CO2) and plastics into different products that are useful in a range of industries...

As the world’s energy demands increase, so does our consumption of fossil fuels. The result is a massive rise in greenhouse gases emissions with severely adverse environmental effects. To address this, scientists have been searching for alternative, renewable sources of energy.

A main candidate is hydrogen produced from organic waste, or biomass, of plants and animals. Biomass also absorbs, removes and stores CO2 from the atmosphere, while biomass decomposition can lead to negative emissions or greenhouse gas removal. But even though biomass heralds a way forward, there is still the question of the best way to maximize its conversion into energy.

Biomass gasification

There are currently two main methods for converting biomass into energy: gasification and pyrolysis...

Scientists at ETH Zurich have built a plant that can produce carbon-neutral liquid fuels from sunlight and air. The next goal will be to take this technology to industrial scale and achieve competitiveness. In a paper published in the journal Nature, researchers from Zurich and Potsdam describe how this novel solar reactor functions and outline a policy framework that would provide incentives to expand the production of “solar kerosene.”

Carbon-neutral fuels are crucial for making aviation and maritime transport sustainable...

1,000-fold improved chemistry leads to ‘artificial leaf’ that makes Syngas. A provisional patent application has been filed by the by University of Illinois researchers. Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device essentially does the work of plants, converting atmospheric carbon dioxide into fuel, solving 2 crucial problems at once. A solar farm of such “artificial leaves” could remove significant amounts of carbon from the atmosphere and produce energy-dense fuel efficiently.

“The new solar cell is not photovoltaic – it’s photosynthetic,” says Amin ...
