It sounds too good to be true. And I am somewhat skeptical. Assuming it works (and that is assuming a lot), it obviously requires energy to create the fuel (my guess is it requires a significant amount of energy). For example you can make hydrogen gas fairly easily at home, but while explosive is not very practical as a fuel source (the cost of generating hydrogen outweighs the benefit of creating it). So they have to prove it can work and they have to show at what cost it will work. These types of programs have shown up before and have not yet panned out. But, let's say that is true and the energy requirements are not enormous, this is the sort of process that can make wind and other renewables economical. The biggest draw back of wind is its intermittent nature and the inability to rely on it for grid electric needs. But if you could potentially make gasoline economically when the wind is blowing, you can effectively store that energy.
Does this mean I am all for Barack Obama's green programs. Heck no. Other than maybe some grants or support of that nature, the government is terrible at this sort of investment picking. Which is why Obama's crony capitalist green programs like Solyndra failed miserably. If this process works it will fund itself. What government needs to do is get out of the way. Venture capitalists will be all over it.

The process involves hydrogenating CO2 using H2. Hydrogen can be derived from many sources: electricity + water; fossil fuels. Your intuition is correct: where does the electricity or fossil fuel energy come from in the first place. An "ideal" scenario would be to split water using sunlight, making H2 and O2, then use the hydrogen to "reduce" CO2 to liquid fuels.
ReplyDeleteI spent a great deal of time trying to making liquid fuels from natural gas. We had to achieve what was called "shutdown economics" in the parlance meaning that the technology had to be good enough and cheap enough to replace the current technology.
ReplyDeleteChubama practices shutdown economics, emphasis on "shutdown."
