America’s energy future. U.S. House hearing 2011
[ It’s always good to look back in time to when our representatives were worried about our dependency on oil. Apparently they were desperate, since the proposed H.R. 909 bill included Coal-To-Liquids (CTL), much of it for the military. I … Continue reading

Gas-to-Liquids (GTL) & Coal-to-liquids (CTL) can not compensate for declining oil production
[ Some of the points made include: As a rule-of-thumb, a 50-60% thermal efficiency can be used for hydrocarbon liquefaction in general assessments. This implies that only half of the coal energy invested in liquefaction will come out as energy … Continue reading

Patzek: CTL coal-to-liquids from FT Synthesis is NOT likely to happen
This is a liquid fuel crisis – diesel to be exact – to keep tractors, trucks, trains, and ships moving. There’s not enough coal or water to make even a small percent of the FT-CTL diesel fuel we need from … Continue reading
