Energy density of coal MrReid

As uranium has an energy density of 79.5 trillion joules per kilogram that means that one kilogram of coal contains 79.5 megajoules of energy as nuclear potential energy. Or in graph format (and remember, this is the best-case scenario for coal and the worst-case scenario for uranium):

Energy density Wikipedia

Energy density is the amount of energy stored in a given system or region of space per unit volume. Colloquially it may also be used for energy per unit mass, though the accurate term for this is specific energy. Often only the useful or extractable energy is measured, which is to say that inaccessible energy (such as rest mass energy) is ignored.

Energy Density of Coal The Physics Factbook

The main use for coal is to produce energy but it can also be used to manufacture steel and is an important source of some of the chemicals used in pharmaceuticals, pesticides and fertilizers. Coal has a relatively high energy density of approximately 24 MJ/kg. Energy density can be defined as the amount of energy per mass.

What Is the Bulk Density of Coal? Reference

The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter.

Power Density Primer: Understanding the Spatial Dimension

gravimetric density of energy converters: when evaluating batteries (whose mass and volume we usually try to minimize) power density refers to the rate of energy release per unit of battery volume or weight (typically W/dm3 or W/kg); similarly, in nuclear engineering power density is the rate of energy release per unit volume of a reactor core.
