Nitrous Oxide emissions associated with 100% hydrogen boilers: research

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.


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.
