Research to measure the gas composition of flue gas from hydrogen boilers under normal, real world operating conditions, with a view to establishing what, if any, greenhouse gases are emitted during combustion.

Conclusions

1. Emission concentrations of N₂O were at the detection limit for all periods except those when the boiler was operating at the high fire mode.

2. The estimated weighted average annual emission of N₂O was 0.272 mg/kWh.

3. The estimated weighted CO₂ equivalent was determined as 0.00007 kg/kWh.

4. The peak values measured during high fire operation were consistent with the other flue gas components measured.
