What happens with the gasoline after it’s made? Does it get burnt again? I’m guessing the energy released from burning that gasoline must necessarily be less than the energy used in creating it. Then the net is going back to square one with regards to CO2, but with a net loss of renewable energy?
I may well be off the mark here, so would appreciate it if someone could tell me what I’m missing.
- rmcginnis 7y agoThe energy content of the gasoline is less than the energy used to make it (only 50-60% efficiency), but the CO2 released is the same as the CO2 used. So the energy efficiency is low, but the net CO2 emission is still zero.
- Zenbit_UX 7y agoIs your device small enough that it could be placed to filter the exhaust emissions from a fuel burning car and reinsert the newly created gasoline into its fuel tank?
- shawabawa3 7y agopowered by what? It would only make sense if there was a carbon free cheap power source you could use to charge it - if you just take it from the car battery you're wasting fuel as it's only ~50% efficient
- po 7y agoI think the idea is that you're powering traditional combustion engines with a fuel generated with green power. It may be more wasteful of that green electricity than a new EV charging from the grid would be but you didn't have to build and buy a new thing and it's kind of fine to waste renewable energy if the economics works out because it's renewable. So it's effectively a way to convert your ICE car into a zero-emission EV by using that fuel.
