Prime movers: efficiency of power generation over time?

How has the efficiency of prime movers increased across industrial history? This data-file profiles the continued progress in the efficiency of power generation over time, from 1650 to 2050e. As a rule of thumb, the energy system has shifted to become ever more efficient over the past 400-years.

Thermal power plant: loss attribution?

This data-file is a simple loss attribution for a thermal power plant. For example, a typical coal-fired power plant might achieve a primary efficiency of 38%, converting thermal energy in coal into electrical energy. Our loss attribution covers the other 62% using simple physics and industry average data-points.

Adiabatic flame temperature: hydrogen, methane and oil products?

At an idealized, 100% stoichiometric ratio, the adiabatic flame temperature for natural gas is 1,960ºC, hydrogen burns 300ºC hotter at 2,250ºC and oil products burn somewhere in between, at around 2,150ºC. The calculations show why hydrogen cannot always be dropped into an existing turbine or heat engine.
