Methods and systems of operating a blockchain mining device using natural gas produced at a hydrocarbon production, storage, or processing site/facility. A generator may be retrofitted to an existing prime mover used to pump the well, and the generator may be used to power the blockchain mining device. Portable mining devices may be hooked up to a casinghead gas supply at a remote, isolated oil facility. Power loading levels may be modulated by adjusting mining transaction levels to correspond with combustible gas production levels.

The present invention relates, in general, to systems and methods for generating hydrogen from ammonia on-board vehicles, where the produced hydrogen is used as fuel source for an internal combustion engine. The present invention utilizes an electric catalyst unit operating in series with a plate-type heat exchange catalyst unit. The electric catalyst unit is used to initiate an ammonia cracking process on-board during a cold start or low load operating condition of the internal combustion engine, where the ammonia cracking process occurs in the heat exchange catalyst unit once exhaust gas from the internal combustion engine has been heated to a threshold temperature suitable to perform the ammonia cracking process.
