This Material Could Turn Greenhouse Gas Into Fuel

Illustration for article titled This Material Could Turn Greenhouse Gas Into Fuel

In the energy world, carbon capture technology is often seen as the Holy Grail: Imagine if we could just suck all pesky climate-changing CO2 out of the atmosphere. Scientists at the DOE are hot on the problem. They’ve just identified a new material that not only captures CO2, it helps convert the greenhouse gas into fuel.


It’s called a copper tetramer, and it consists of small clusters of four copper atoms each, supported by a thin film of aluminum oxide. Copper tetramers bind tightly to CO2 and help catalyze its conversion into methanol, which can be stored or burned again for fuel.

It’s a great example of how new materials might help close the loop on carbon emissions. But the catalyst has a long way to go before it’s ready for prime time. So far, scientists have only manufactured small amounts of the stuff, and the material’s long-term durability is unknown. Concepts like this are exciting, but if we want to avoid the worst effects of climate change, there’s no getting around the fact that we need to wean ourselves off carbon-based fuels in the first place.

i dont like this. sure its cool and new and sciency and stuff, but i would argue that it perpetuates the continual use of fossil fuels. if we converted to an entirely green community of people on the planet, and reduced carbon emissions to close to nil, this material becomes considerably less useful, no? Could I not argue that the widespread use of this gives reason for multi-billion dollar fossil fuel conglomerates to continue pumping crap into the air?

i guess there’s something to be said for the removal of c02, but i feel like my point is still valid.
