MRE uses the following information to make energy conversions to help formulate sizing and energy requirements for various micro grid projects.
An example of using the information above in a formula to find out how many kilowatt hours are in a kg of hydrogen:
423 scf x .0791 KWH per scf = 33.45 KWH of electricity in a kilogram of hydrogen.
In order to utilize this hydrogen in a fuel cell, you must multiply the 33.45 KWH by .55 (or the efficiency of an average fuel cell). You will arrive at 18.40 KWH of usable electricity available after running it through the fuel cell.
