Benefits of Hydrogen

  • Hydrogen is the most abundant of all elements in the universe.
  • Hydrogen can replace gasoline, diesel fuel and natural gas.
  • Hydrogen like electricity is classed as an energy carrier.
  • Hydrogen can be produced and consumed with zero impact on the environment.
  • Hydrogen can be used to fuel internal combustion engines (ICE) and fuel cell vehicles. A fuel cell car can go 2.8 times farther on a kilogram of hydrogen than an ICE car on a gallon of gasoline.
  • Hydrogen can be used to cook and heat with.
  • Hydrogen can be used to store mega watt utility scale energy.
  • Hydrogen will reduce the dependence on imported fuels.
  • Hydrogen is as safe, and in many cases safer, than the use of gasoline, diesel or natural gas.
  • Hydrogen produced by renewable energy can enable sustainable energy independence.
  • Hydrogen working with batteries and renewables can enable Smart Micro Grids to become the status quo.

Hydrogen Conversion Information

MRE uses the following information to make energy conversions to help formulate sizing and energy requirements for various micro grid projects.

  • 423 standard cubic feet (scf) = 1 kilogram (kg) of hydrogen.
  • It takes 2.3 gallons of water to create 1 kg of hydrogen.
  • There are .0791 kilowatt hours of electricity in a scf of hydrogen.
  • 1 kg of hydrogen is equal to 1 gallon of gasoline in btu equivalent.
  • MRE electrolyzers require 48 kilowatt hours (KWH) of electricity to produce 1 kg of hydrogen. More energy is required to compress and purify the hydrogen ranging from 5 to 15 KWH per kg, dependent on size of system.
  • A fuel cell's efficiency, on average, is about 55%.

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.

  • The round trip efficiency from taking electricity and converting it to hydrogen with MRE's electrolysis process, then purifying it and compressing it, and then converting the hydrogen back to electricity in the average fuel cell, is approximately 35%. It is important to consider that in the case of over production from wind and solar, this excess energy produced represents a 35% increase in available energy, versus what some might think is a 65% loss.
