Electricity From CO2 — New Technique



Here’s an interesting article from sister site Planetsave regarding a long-discussed topic that hasn’t gotten very far — using CO2 to create electricity. Check out the latest research update in this field:

New Technique Generates Electricity From CO2 Pollution (via Planetsave)

A new technique developed by a team of Dutch Engineers generates electrical power from a novel mixing of CO2, air and water — without increasing CO2 emissions. Carbon dioxide (CO2) is a simple molecule that results from either the natural breakdown…

    I’m not sure this is a good idea… if I have understood the idea correctly, it means extracting the very energy that would have to be supplied for pulling down CO2 from the ambient air (as opposed to using power-plant smokestacks) in preparation for underground sequestration. Right?

  • Ronald Brakels

    At 4.5 mW a square meter it would take about half a million square meters of surface area to collect enough wattage to run the heating element in my oven. Think I’ll stick to solar cells.

  • JamesWimberley

    Is the technology helpful? It would make fossil-burning power stations more efficient overall, and reduce the CO2 per kwh of fossil electricity. On the other hand, it will prolong their economic life and slow down the clean energy transition. Development is not a priority.

    • Bob_Wallace

      Exactly, all these schemes to use the concentrated CO2 stream from fossil fuel plants will make it harder to close those plants.

  • Marion Meads

    They have calculated an energy efficiency of 24% to 32%. What is the basis of this efficiency? Clearly we know the output is electricity, and it is 24% of what input energy? What is the input or the main energy source? Has the energy costs for pumping water and bubbling the air also been accounted for?
