Sandia National Labs created a prototype that could “reverse-combust” CO2 back into fuel. CO2 can be produced by a variety of sources, but combustion of carbon containing fuels (methane, petroleum, coal, wood, etc) is the largest producer. An example of a chemical reaction could be what occurs between methane and oxygen: CH4 + 2O2 -> CO2 + 2H20 (2). Basically when CO2 is produced, the chemical reaction usually results in CO2 and water. Scientists at Sandia National Labs have discovered that they can produce carbon monoxide using solar energy, water, and CO2. The process can also create raw hydrogen. While it’s only a prototype, and the reverse-engineered syngas procedure isn’t anywhere near being economical, it gives a glimmer of hope to those anxious for renewable energy solutions.
