Emissions data for Bio Liquefied Natural Gas (Bio-LNG) & Biomethane
Based on the Bioenergy data of UK Government GHG Conversion Factors for Company Reporting documents states that at peak load, a 530kW CHP will consume 109kg of Bio-LNG per hour.
At full load it will produce 1.9kg of emissions per hour (719kg per year).
The Scope 1 conversion factors presented in this listing contain values for N20 and CH4 emissions, (which are not absorbed during growth of the Bio-LNG feedstocks).
Based on the Outside of Scope data, at peak load, the 530kW CHP will consume 109kg of Bio-LNG per hour. It will emit 1 tonne of CO2 per day at full load, equating to 383 tonnes per year.
According to government data, the emissions for a CHP running on biomethane are considered zero.
This is because the amount of CO2 absorbed during the production of the biomethane offsets the emissions. Although the Out of Scope figure needs to be documented to ensure complete accounting for the emissions produced.
As of August 2025, indicative pricing for delivered Bio-LNG is £0.05 per kWh
CHPs running in island mode (operating independently as an isolated power source, with no grid input) generate zero CO2 electricity for 12p/kWh.
