Making petrol from air and water
14 Answers
Reported in the Independent Newspaper today is the news that scientists have made petrol from the carbon dioxide in the air and hydrogen in water.
Air Fuel Synthesis, of Stockton-on Trent, have produced 5 litres of petrol in their laboratory.
The Institute of Mechanical Engineers have verified their experiment

It takes energy to produce petrol from its chemical constituent components (H, C and O). What this organisation has done is taken energy from somewhere else (electricity from the Grid, wherever) to do this. If that energy was generated from a renewable source (a solar panel, say), then the petrol is 'free', but in no more way than stuffing a load of solar panels on your roof.
A lot of technical equipment (which initself requires resources to produce) is required to enable the conversion - a bit like soalr panels. But eventually there could be economies of scale in making the necessary equipment.

The main point is that once we generate a significant proportion okf electricity from renewable sources there will be times when a surplus of energy is being generated, and apart from the pumped storage reservoir at Dinorwic, we have no way of storing it. If we could convert that surplus energy into liquid fuel (using carbon dioxide which is in, or would otherwise go into, the atmosphere), we could also begin to decarbonise transport emissions. The attraction of this approach is that the methanol produced can be added to petrol and burned in existing engines without modification (as in Indy car racing or as we used to do during the second world war). The alternatives - charging up electric cars, or using hydrogen - require enormous infrastructure investments, which this doesn't. It does, however, need time and money to develop into a scaled up and commercially viable process.
The Daily Mail has a useful schematic on how the methanol is produced.

This isn't that spectacular an achievement - very promising but just a start.
It's important because petrol or diesel is just about the best way of transporting energy - beats hydrogen into a cocked hat.
This process would seem to be essentailly carbon neutral.
As hinted above it's all about efficiency and scaling
If you lose 99.99% of the energy in making it there's no future
At first penecillin could only be produced in tiny quantities but was made to scale - on the other hand high temperature superconductors have yet to make it out of the lab.
But if it can be made to scale and is modestly efficient dessert coutries with a water supply could be set as the world's petrol suppliers. So I guess Namibia's going to be the place to be!
