Qnergy provides remote power solutions to help companies improve operational efficiency and reduce emissions. One of the leading applications is instrument air solutions to displace methane emissions from pneumatic devices.

Deployment case study

Challenge

Across many of the world’s natural gas production fields, gas pneumatic devices used for process control and chemical injection vent methane directly into the air. TotalEnergies lowered the methane emissions intensity of its operated gas facilities to below 0.1% in 2020, but to achieve a further objective of 20% reduction of absolute methane emissions from operated oil and gas assets in 2025 compared to 2020, it targeted venting at its Barnett gas field in Texas.

Solution

In March 2021, TotalEnergies began a 30-day trial of Qnergy’s CAP3 compressed air pneumatics technology. The pilot study sought to quantify and characterize the pneumatic gas and electric power requirements of a typical 4-5 well pad on the Barnett field. It tested the feasibility of converting from natural gas to compressed air powered instrumentation, thus eliminating methane release during the process.
