In reading a text about $\ce{CO2}$ recycling and sequestration of various kinds, I came to think about storing atmospheric $\ce{CO2}$ as asphalt. Given cheap energy as in the case of Iceland, and improved atmospheric carbon capture technologies, could this be feasible? Is there a name for the reverse cracking process?

    $\begingroup$ Organic revers process to cracking is called Photosynthesis. $\endgroup$ – Jaroslav Kotowski Aug 20 '15 at 14:50
  • $\begingroup$ Well, I was thinking of building very long carbon chains, that's not photosynthesis, is it? Photosynthesis would just be the first step, right? $\endgroup$ – nordmarj Aug 20 '15 at 14:53
  • $\begingroup$ An alternative to photosynthesis will be great breakthrough. $\endgroup$ – Jaroslav Kotowski Aug 20 '15 at 15:01
  • $\begingroup$ Reducing CO2 back to alkanes (not neseserily using light energy) isn't viable as we're burning fuel to get energy - so what one country would be producing energy and the other losing it to reverse it? $\endgroup$ – Mithoron Aug 20 '15 at 21:41

    $\begingroup$ See this article sciencedaily.com/releases/2015/08/150819083117.htm They have an aike idea. $\endgroup$ – Jaroslav Kotowski Aug 21 '15 at 7:37
