Between 2000-2005 US Oil&Gas Cos spent $75-100 BILLION
on alternative energy!!

As the poster above alluded to, a lot of money was spent (mostly in vain) on GTL. Oil companies have thrown lots of money at alternative energy, though. Shell and BP both have large solar divisions that absorbed a lot of that money. Shell has also spent a lot of money on shale. My former company, ConocoPhillips, has put a lot of money into various technologies - most notably green diesel.

What do they have to show for it? They are up against the same laws of chemistry, physics, and economics as everyone else. They, like many others, have confirmed that there is no silver bullet. It's hard to find any true silver BBs either. I just blogged on how over-blown the hype around Coskata has gotten; I will probably bring that over to TOD in a few days.

Thanks.

I've also noticed that commerical GTL installations are not moving that fast.

Whats interesting is GTL seems to me at least to be the easiest of the synthetic fuel methods.

Also you have excess hydrogen that could be coupled with Ammonia synthesis so selling Ammonia should help a lot with the cost aspect. Other synfuel sources don't have this excess hydrogen.

Given that GTL is in my opinion the best alternative to oil I find it interesting that its not growing like it seems like it could.

Do you have and opinion on whats causing GTL to stumble ?

Having spent a few years on GTL, I know exactly what's causing it to stumble: Capital costs.

You are right, GTL is the easiest. That should put the rest of these gasification schemes into perspective. If GTL is the easiest (and cheapest), then what does that suggest about these CTL and BTL schemes? That they are a long ways off.
