Fugitive gas emission mapping & quantification

In collaboration with MIRICO Ltd and Shell SGSI, the group has developed a novel laser sensor for long open path sensing and demonstrated, during a controlled release test, that the measurement system could accurately map and quantify mass emission rates of methane seeping from the ground. The field deployment was organized at the Chilbolton Observatory, Hampshire, where large areas could be monitored (150×100 m2) with a single fixed instrument. Owing to the novel dispersion laser spectrometer technology pioneered in the group, scintillation or bad weather were found not to impede the open path measurement quality.

This great demonstration has led the group to be involved in the Science for Clean Energy (S4CE) H2020 project led by UCL to develop and deploy further the instrument  for geo-energy applications.
