I can't conceive of anything that would reasonably replace diesel for outdoor heavy equipment, either.

  >I can't conceive of anything that would reasonably replace diesel for outdoor heavy equipment, either. Believe it. Heavy equipment is a prime candidate for electrification. Mining companies are already using electric dump trucks in production, and they are incredibly more efficient because of regen braking with the mass differential of unloading at the bottom of a hill [0]. Literally anything that isn't dependent on the energy density of hydrocarbons will be electrified in the next few decades. That leaves basically aircraft and spacecraft as consumers outside the petrochemical and energy industry.
