Brayton cycle engines compress and heat air with a fuel suitable for an internal combustion engine. For example, burning natural gas or biogas heats compressed air, and then a conventional gas turbine engine or the rear portion of a jet engine expands it to produce work. Compressed air engines can recharge an electric battery. The apparently-defunct
Compressed hydrogen storage method is the physical storage of compressed hydrogen gas in high pressure tanks (up to 10,000 pounds per square in.). This method is beneficial for fuel purposes, because in this form it can be stored in a smaller space while retaining its energy effectiveness [28–30] .
