Additional Applications for E-Flux Fossil Fuel Traps

In addition to tracking LNAPL degradation rates, the innovative E-Flux Fossil Fuel Traps can be used for a broad range of other monitoring scenarios, including:

Carbon capture and sequestration. Carbon capture and sequestration (storage) involves capturing waste carbon at large industrial sources and depositing it at a storage site (typically a deep geologic formation) to prevent it from entering the atmosphere and to help mitigate fossil fuel contributions to climate change. E-Flux Fossil Fuel Traps can estimate the rate of leakage from storage formations into the atmosphere. Carbon isotope dating can then reveal whether the leak is coming from stored fossil fuel or from modern sources of carbon. Background measurements taken before storage can help establish a baseline of carbon leakage from natural sources.

Natural gas extraction. As regulatory agencies increasingly require the use of technologies that ensure leak-free wells and transfer processes, E-Flux Fossil Fuel Traps can provide natural gas providers with a cost-effective tool for monitoring stray gas leakage from wells. Because methane undergoes constant change in the ground (becoming CO2 due to microbial activity), E-Flux Fossil Fuel Traps can enable monitoring of CO2 fluxes at grade, using isotopic techniques to determine whether the sources are modern or of fossil fuel origin.

Contaminant emissions. Emissions from ground contaminants such as gasoline (also known as semi-volatile compounds) exit the ground as soil gas flux. Through a process known as soil vapor intrusion (SVI), these emissions sometimes impact indoor air quality above a contaminated site. The E-Flux Fossil Fuel Trap's proprietary design can be applied to these semi-volatile contaminants to measure their soil gas flux. Appropriate sorbents and measurement methods required for this application are already developed and approved for gas sampling.

E-Flux Fossil Fuel Traps are the ideal solution for:

  • Identification of zones where LNAPL natural attenuation is active
  • Long-term monitoring
  • Remote or limited access sites
  • Cost-controlled budgets
  • Minimizing environmental footprint of monitoring activities
  • Documenting natural source zone depletion (NSZD)
