What if we found a system to transform one of our big "enemies" into a fuel again, and then, when produced, re-transformed again? This is the aim of a project made at University of Nottingham's Centre for Innovation in Carbon Capture and Storage (CICCS), in the UK, directed by Mercedes Maroto-Valer. They have successfully completed a cycle of transforming CO2 into natural gas (CH4). This could lead to making most carbon capturing processes obsolete while also powering cars we already have. According to Ms. Maroto-Valer, the CICCS group tacked the problem by studying what plants do - capturing CO2, water and solar light and transforming it into carbohydrates - and then replicated the process to create methane instead of carbs. However, it's still unknown what the energy balance the system is - we can't defeat the laws of Thermodynamics, after all.
