Biogenic CO2 Sampling
The Environment Agency now requests plant operators to report Pollution Inventory (PI) emissions to include biogenic CO2 sources.
Who Does This Affect?
There is a requirement to monitor biogenic CO2 in any applications in which emissions are reported for regulatory and GHG inventory:
- Energy from Waste
- Electricity generation (biomass or mixed fuels)
- Coal co-firing (mixed fuels)
- Cement and lime production
The Most Accurate Sampling Method
By using the ratio obtained from the continuous C14 sampling method, and the total CO2 emitted by the plant, the amount of CO2 from biogenic sources can be calculated.
As a result, this method will return the most accurate figures for reporting biogenic CO2 emissions.
The automated sampler extracts CO2 samples from exhaust gas in the flue via a heated sampling probe. An absorber cartridge filled with sodium hydroxide or soda lime determines the biogenic fraction of CO2 emissions.
- Enables sites to claim ROCs for reporting biogenic fractions
- The sampling principle fulfils the requirements of EN ISO 13833
- It is continuous and therefore fully representative of the feedstock
- Fully automated and requires no intervention
How Does it Work?
The AMESA-B, a continuous and automated sampler extracts CO2 samples from exhaust gas in the flue via a heated sampling probe. The sample is transported to the enclosure.
An adsorber cartridge filled with sodium hydroxide or soda lime, used to determine the biogenic fraction of CO2.
Typically, at the end of each month, samples from each test rig are collected, processed, and sent to an authorised analytical laboratory.
The laboratory undertakes 14C spectrometry and provides the operators with the results in a report.
