1. Differences in calorific value
The calorific value of CO (carbon monoxide) is approximately 283 kJ/mol or 3.0 kWh/m³. This corresponds approximately to the calorific value of hydrogen. Natural gas (methane), on the other hand, has a higher calorific value of around 890 kJ/mol or 11.1 kWh/m³.
In comparison with these two fuels, our fuel has a considerable advantage: it is burnt with the pure oxygen obtained during fission.
2. Combustion of CO with pure oxygen
Because we burn the carbon monoxide (CO) with pure oxygen (O₂), there is no nitrogen as a ‘co-runner’ in the reaction. All the energy from the combustion can be converted directly into usable heat.
This leads to a higher thermal efficiency, as there are practically no losses due to the heating of inactive gases.
3. No energy losses
Natural gas is burnt with ambient air. This only contains approx. 20% oxygen and 78% nitrogen, which has to be heated, although it does not contribute to the combustion reaction itself.
A considerable proportion of the energy is therefore lost, as the nitrogen absorbs the heat from the combustion and releases it unused into the environment.
Conclusion
- The combustion of CO with O₂ is particularly effective because it takes place with pure oxygen and is therefore practically loss-free.
- Almost 100% of the resulting thermal energy can be invested in the process.
- CO₂ is only released once at the start of the heat cycle.
- The purchase of fossil fuels accounts for this proportion.
- The need for CO₂ certificates is significantly reduced.
