[font size=5]Recycling carbon dioxide: U of T researchers efficiently reduce climate-warming CO₂ into building blocks for fuels[/font]

[font size=3]Turning carbon dioxide into stored energy sounds like science fiction: researchers have long tried to find simple ways to convert this greenhouse gas into fuels and other useful chemicals. Now, a group of researchers led by Professor Ted Sargent (ECE) has found a more efficient way, through the wonders of nanoengineering.

Drs. Min Liu and Yuanjie Pang, along with a team of graduate students and post-doctoral fellows in U of T Engineering, have developed a technique powered by renewable energies such as solar or wind. The catalyst takes climate-warming carbon-dioxide (CO₂ ) and converts it to carbon-monoxide (CO), a useful building block for carbon-based chemical fuels, such as methanol, ethanol and diesel.

“CO₂ reduction is an important challenge due to inertness of the molecule,” says Liu. “We were looking for the best way to both address mounting global energy needs and help the environment,” adds Pang. “If we take CO₂ from industrial flue emissions or from the atmosphere, and use it as a reagent for fuels, which provide long-term storage for green energy, we’re killing two birds with one stone.”



When they applied a small electrical bias to the array of nanoneedles, they produced a high electric field at the sharp tips of the needles. This helps attract CO₂, speeding up the reduction to CO, with a rate faster than any catalyst previously reported. This represents a breakthrough in selectivity and efficiency which brings CO₂ reduction closer to the realm of commercial electrolysers. The team is now working on the next step: skipping the CO and producing more conventional fuels directly.

CO2 -> fuel -> CO2. It still ends up in the air, just with an energy-consuming middleman. Binkie The Clown Aug 2016 #5

Effectively, it’s the same as running things on renewable electricity, with one very big difference. Fuels store really well in tanks.

There are so many unrealistic utopian ideas being floated around that I tend to flip into skeptic mode as my automatic default. Maybe there's something to it. I'll retract my objection for now and adopt a wait-and-see.

...capture.

We have a subset of people on this planet, unfortunately many of them in the Democratic Party, our party, who actually believe that electricity comes out of a wall socket connected entirely to wind and solar carbon free plants.

This delusion is nonsense, and in fact dangerous, since this belief is minimizing the reality that fossil fuel use to generate electricity is growing at an alarming rate, and thus, the collapse of the planetary atmosphere is occuring at the highest rate ever observed.

There is no way that this lab scale process could be commercialized - even rapidly - and be "carbon neutral." To claim so is to be fraudulent.

...energy to produce methanol fuel by the electrochemical reduction of carbon dioxide, based on papers by Andrew Bocarsly of Princeton University, recently shut its doors.

They just learned that lab based stuff doesn't mean doodley squat if it can't be commercialized and scaled.

Liquid Light Hype.
