EROEI

australia · Guest

Anybody have any idea of the Energy Retrun on Energy Invested for Gas to Liquids conversion process?
I read that currently, Natural gas has an EROEI betwen 5-10.
Although oil had a very high (100) ratio years ago, now it also is about 10.

So what about the conversion process?
Any one seen any data?

.......thanks....AR

I read that 30% of the energy was lost in the process of liquifying / re-gasifying methane for transport via LNG tankers.

I don't remember from where though.

Maybe I wasn't clear......natural gas conversion to oil. Not gas to LNG.

No, but the EROEI of converting tar sands and oil shale to useable product is pathetic. I'd imagine gas-to-oil wouldn't be much better...or they'd be catching all the methane coming out of the thawing Arctic ground and be converting away!

NOTHING replaces oil & gas--and their EROEIs are now in the frightening ratio! Shocked

Gas to liquids conversion is a bit better than tar sands. The efficiency is around 60 - 70% for gas to diesel. If the EROEI of gas drilling is around 5 to 1, then EROEI of gas drilling to diesel should be about 3.5 to 1, significantly better than tar sands and oil shale.
