Hydrogen production zero energy

Natural gas is converted in a fuel cell to a mixture of hydrogen and carbon monoxide (syngas). The syngas is reacted with steam to produce more hydrogen plus carbon dioxide.

The fuel cell generates electricity. This is used to power water electrolysis, to produce even more hydrogen.

The CO2 from this reaction is mixed with natural gas and air in Omnagen's SPOCC Reactor, which converts it into a carbon-rich syngas for use in the chemical industry. No external energy is required for this reaction.

This method extracts the maximum useful energy out of the natural gas. It also avoids the release of CO2, as the carbon-rich syngas produced by the SPOCC Reactor can used to make a huge range of chemicals.

Hydrogen Production Reactions

Solid Oxide Fuel Cell

Anode reaction:- CH4 + O2- = CO + 2H2+ 2e-
Cathode reaction:- ½O2 + 2e- = O2-
Overall:- CH4 + ½O2 = CO + 2H2 + electricity

PEM Electrolyser or Solid Oxide Electrolyser

electricity + H2O = ½O2 + H2

Water-Gas Shift Reaction

CO + H2O = CO2 + H2


SPOCC Reactor

Overall:- 2CH4 + CO2 + ½O2 = 3CO + 4H2

 


SPOCC Reactor reusing CO2

Omnagen’s innovative self-powered CO2 converter; a device which converts carbon dioxide, methane and air into useful chemicals, without the need for external energy. This is how the device works.

Carbon dioxide is a very stable molecule, it will react with some minerals to form stable carbonates, but other reactions require energy. Photosynthesis, for example, uses energy from the sun to convert CO2 and water into glucose and oxygen.


Carbon dioxide storage

CO2 is only a problem if it is in the earth’s atmosphere. The greenhouse effect is explained here.

Carbon Capture and Storage (CCS) involves capturing CO2 from the air, or exhaust gases, liquifying it, and then burying it. This is expensive, but it will allow fossil fuels to be used without releasing carbon dioxide into the atmosphere. More details about CCS.
