*Perhaps this synthetic sequence could remove CO2 from the air at low cost and high throughput. (1) Electrolysis of water (solar or wind energy) -----> hydrogen gas http://en.wikipedia.org/wiki/Electrolysis_of_water (2) Haber process using hydrogen gas from (1) + nitrogen from air ----- > ammonia http://en.wikipedia.org/wiki/Haber_process (3) Carbonic anydrase in water + CO2 from air -----> carbonic acid -----> carbon dioxide gas http://en.wikipedia.org/wiki/Carbonic_anhydrase (4) carbon dioxide from (3) + ammonia from (2) ------> urea http://en.wikipedia.org/wiki/Urea (5) urea -----> cyanuric acid -----> land fill http://en.wikipedia.org/wiki/Cyanuric_acid Step 3) would reduce CO2 levels rather than just avoid increasing them (as with carbon capture), in case of a real emergency in which we must remove CO2 or perish. Step 1) could put wind and solar energy equipment to good use for a change, and less need for cooperation by existing electrical grid operators than renewable energy projects normally entail. As to the energy consumption of the Haber process, it may be reasonable since the hydrogen is not from reformation of methane.
