The energy formula: ERoEI

Energy Return on  Energy Invested - Costs (production::distribution) > 0 or bust!
since Lavoisier (Nothing is created, nothing is lost. evurithing is transformed), every transformation of one energy into another draws a loss. The loss is at the efficiency level of the process involved.

What also needs to be taken into account in the ERoEI formula is the environmental impact: if you produce energy, but also have waste as byproduct, the treatment of that waste has to be taken into account. Sooner or later.

Oil Note: oil has to be transported. One index to keep in mind is the Baltic Dry Index. Link on Slate.

  Natural gas

GTL

Basically, natural gas molecules are broken then re-assembled in longer molecules by a catalytic process.
Resulting in the transformation of gas into a liquid at normal temperature and pression, distributable as any liquid at a classic gas station pump. Can be used for diesel engine without transformation along bio-diesel or classic diesel.

Coal  
  Hydrogen


using methane (from oil, coal, gas, livestock,...) to produce hydrogen has a carbon dioxyde by-product (CH4 = H2 + CO2). Not taking into account the losses of the process,  the costs to stock and distribute hydrogen, an hydrogen engine would effectively be clean (exhaustin pure water: 2H2 + O2 = 2H2O), but the dioxyde already has been released earlier in the production.
Plain stupid. Just KISS, power the engine with methane!
