Energy is transported over land primarily by electric power transmission lines and by pipelines carrying gas or liquid fuel. Pipelines today carry fossil fuels, but in future will carry renewable fuels. The fuel power density is F=ρhh, where ρ is the density and h the specific enthalpy of combustion. It is a figure of merit by which candidate renewable
