Reply to comment by Tearakan in Researchers unveil the least costly carbon capture system to date - down to $39 per metric ton. by PNNL

Cycling carbon from the atmosphere into our fuel, burning that fuel, and releasing the same carbon back into the atmosphere is still substantially better than pumping new carbon out of the ground and burning that into the atmosphere. It’s not perfect or ideal, but it’s still so much better than what we’ve got now.

The issue is we literally can't use that fuel to actually bring the carbon back out of the atmosphere. We run in laws of thermodynamics that stop us there.

Burning something that creates co2 and then using said energy to recapture it will end up in a net energy loss.

It’s not a complete solution on its own, you’re correct there. Combined with renewables and nuclear power to help minimize the use of fossil fuels in energy generation, there may be actual possibilities.

We’re decades out from the “perfect” solution to climate issues, so in the meantime, we have to continue investigating and researching solutions and finding ways to combine and utilize existing technologies to the end goal of minimizing carbon output for our existing societal needs, including energy, food production, transportation, etc.

It’s a multifaceted issue.
