1. What’s your great idea for capturing carbon emissions from existing power plants today?

Explanation:

The use of NaOH to scrub carbon dioxide;

2NaOH(aq) + CO₂(g) → Na₂CO₃(aq) + H₂O(l)

The Na₂CO₃ would then reacted with CaOH to form limestome;

Na₂CO₃(aq) + Ca(OH)₂(s) → 2NaOH(aq) + CaCO₃(s)

NaOH would then be regenerated and used again to scrub more carbon dioxide.

Carbon dioxide for industrial use can then be obtained by burning the CaCO₃.

CaCO₃(s) → CaO(s) + CO₂(g)
